Abstract

Cooking oil that is used repeatedly is very harmful to health. The use of cooking oil repeatedly and continuously in the frying process will result in a degradation reaction, thereby reducing the quality of the cooking oil. Therefore, the purification of used cooking oil needs to be done with the aim of making use of consumable oil and to reduce the risks that can endanger health if using used oil repeatedly. The purpose of this research is to find out the heat energy produced by the band heater during the refining process of used cooking oil with activated charcoal. Knowing the effect of band heater power on the heating time of used cooking oil in the refining process. Changing the ratio of oil composition to activated charcoal to visual purification results. This research method uses a comparison between testing with numerical simulations using Ansys. Based on research, it is known that the greater the heating power used, the less time it takes to heat the oil up to 100oC, the time needed for the process of refining used cooking oil is the fastest, namely for 2 hours 30 minutes with a composition of 80%: 20% with the heat flux used 5500 W/m2, and which required a longer time of 4 hours 45 minutes with a composition of 60% : 40% with the heat flux used 3500W/m2. Visually, the best purification results were obtained, namely with a composition of 70% used cooking oil and 30% activated charcoal with a yellow-orange color, while visually the poorer results were obtained with a composition of 80% used cooking oil and 20% activated charcoal with a reddish yellow color. Thus the composition ratio between used cooking oil and activated charcoal affects the results of the refining process, where visually the best composition ratio is 70% used cooking oil and 30% activated charcoal with a stirring speed of 120 rpm. The highest percentage of free fatty acid (BA) reduction in this study was 73.05% and the highest percentage of peroxide value (PV) reduction was 56.88%.

Abstract

In recent years, research is directed towards enhancing the thermo-physical properties of single-component nanofluids. Hence, a hybrid or composite nanofluid is developed to improve heat transfer performance. The thermophysical properties of the Al2O3-TiO2-SiO2 nanoparticles suspended in the base of water (W) and ethylene glycol (EG) blends with vol 60:40 or Ternary Nanofluids for various volume concentrations are investigated. The experiments were undertaken for the concentration volume of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0% of Al2O3-TiO2-SiO2 nanofluids with 30, 40, 50, 60 and 70 °C. Thermal conductivity measurements and dynamic viscosity are carried out at temperatures ranging from 30-70 °C.  The highest thermal conductivity of Ternary nanofluids was obtained at a concentration of 3.0%, and the maximum increase was up to 27.1% higher than the base fluid (EG/W). Ternary nanofluids at a concentration of 0.5% give the lowest effective thermal conductivity of 14.4% at 70°C. Meanwhile, the evidence from the dynamic viscosity of the Ternary nanofluids is influenced by concentration and temperature. Furthermore, Ternary nanofluids behaviour as Newtonian fluid in volume concentration from 0.5-3.0%. The development of a new correlation for thermal conductivity and dynamic viscosity of Ternary nanofluids are precise. In conclusion, the combination of enhancement in thermal conductivity and a dynamic viscosity at a concentration of 3.0% has optimum conditions, which have more advantages for heat transfer than at other concentrations.

Abstract

The use of increased heat transfer techniques, can improve the thermal performance of the tubes. Computational fluid dynamics studies have been carried out to study the heat transfer characteristics and friction factor of the Al2O3-TiO2-SiO2 nanofluids-ethylene glycol (EG)/water (W) (40:60) flowing in the plain tube. The three-dimensional turbulent k-ε model that can be realized with enhanced use of heat treatment on the wall is used for turbulent flow regime. The overall evaluation of tubular performance-tested is based on thermo-hydrodynamic performance index. The results showed that behavioural differences depend on the selected parameters to compare tri-hybrid nanofluids with the base fluid. In addition, the heat transfer coefficient increases with the increase in volume concentration of nanoparticles at the same Reynolds number. The friction factor of Al2O3-TiO2-SiO2 nanofluids decreased exponentially with an increase of Reynolds number. The conventional correlations that have been used in turbulent flow regimes to predict heat transfer rates and friction factors are Dittus-Boelter and Blasius correlations, for tubes also apply to tri-hybrid nanofluids tested which assume that tri-hybrid nanofluids have a homogeneous fluid behaviour.

Abstract

The TRIGA reactor is equipped with a primary cooling system that transfers heat from the reactor tank water to the secondary cooling system. Heat transfer in this system occurs mainly in plate-type heat exchangers located in the reactor building, using forced convection with the help of primary and secondary pumps. This research aims to evaluate the effectiveness, efficiency, heat transfer rate, and temperature difference. The analysis was carried out through CFD (Computational Fluid Dynamics) modeling using ANSYS Spaceclaim for geometric design and ANSYS FLUENT for simulation. Simulations using ZrO2-Water Nanofluid with volume concentrations of 0.2%, 0.6%, and 1% and variations in mass flow rates of 15 kg/s, 20 kg/s, and 25 kg/s. The simulation results show the distribution of temperature, pressure and fluid velocity. The theoretical analysis of the plate type heat exchanger shows that the use of ZrO2 with a concentration of 1% has the highest efficiency, which is 3.39% at a mass flow rate of 25 kg/s, and an efficiency of 64.82% at a mass flow rate. as much as 15 kg/s.

Abstract

Tribological properties are crucial for air-conditioning system performance. The properties can be improved using nanolubricant. However, the effect of the binary ratio of hybrid nanolubricants on the tribological performance of automotive systems is limited in the literature. Therefore, the present study investigates the tribology performance of TiO2-SiO2 nanolubricants for application in automotive air-conditioning (AAC) systems. The dispersion of TiO2 and SiO2 into PVE lubricant was carried out using a two-step method. Subsequently, the dispersion stability was assessed qualitatively and quantitatively. The samples were characterised by a volume concentration of 0.010%, with variations in the mixture ratio of 20:80, 40:60, 50:50, 60:40, and 80:20. Coefficient of friction (COF) and wear scar diameter (WSD) values were determined using the Koehler Four-ball Tribo Tester and Light Compound Microscopy. The investigation revealed that each sample experienced a reduction in COF, with the 40:60 ratio demonstrating the best ratio with the most significant decrease of 37.09%. At the same time, the COF decreased by 8.34%, 2.12%, 7.37%, and 15.11% for the nanolubricant samples at 20:80, 50:50, 60:40, and 80:20, respectively. The WSD evaluation showed that the 40:60 ratio has the lowest scar diameter of 0.0344 mm and a 37.09% wear rate decrease compared to pure lubricant. Each sample exhibits superior performance when evaluated for tribological characteristics and performance, particularly in the case of nanolubricants with the 40:60 ratio. The TiO2-SiO2/PVE, characterised by a volume concentration of 0.010%, has remarkable efficacy across different binary ratios, making it highly recommended with a 40:60 ratio for lubricating AAC compressor systems.

Therefore, hybrid or composite nanofluids are developed to improve heat transfer performance. The thermophysical properties of ZrO2-SiO2 nanoparticles suspended in a mixture of water (W) and ethylene glycol (EG) with vol 60:40 or Green Nanofluids for various volume concentrations were investigated. Experiments were performed for volume concentrations of 0.1, 0.2, and 0.3% of green nanofluids at 50, 60, 70, and 80°C. Measurements of thermal conductivity and dynamic viscosity are performed at temperatures ranging from 50-80°C. The highest thermal conductivity of the green nanofluids is obtained at a concentration of 0.3%, and the maximum increase is up to 37.5% higher than the base fluid (EG/W). Meanwhile, evidence from the dynamic viscosity of green nanofluids is affected by concentration and temperature. Furthermore, the green nanofluids behave as a Newtonian fluid in a volume concentration of 0.1-0.3%. In conclusion, the combination of increased thermal conductivity and dynamic viscosity at a concentration of 0.3% has optimal conditions, which has more advantages for heat transfer than at other concentrations.

Abstract

Three problems are being faced simultaneously by Earth today: water (wastewater), energy, and food. However, considering the finite amount of land and the depletion of fossil fuels, this expansion is incompatible with the replenishment of natural resources in terms of both quantity and quality. Furthermore, another sustainable energy source that has gained international attention is biodiesel. However, research on the relative flash durations of Maggot BSFL oil has not been conducted. Consequently, this article will compare the flame times of many other types of oil with Maggot BSFL oil. This study uses a variety of oils as experimental subjects, including BSF maggot oil, used cooking oil, Pertamina Dex, and a combination of Pertamina Dex and BSF maggot oil. Analysis of the variations in flame time for each type of oil is done using statistical analysis. According to this analysis, the mixture of Maggot BSF oil and Pertamina Dex had the maximum flame, lasting between 16.31 and 16.44 minutes. Additionally, this study offers data on the notable variations in flame length for each type of oil, including used cooking oil, Pertamina Dex, Maggot BSF oil, and a combination of both. When creating biodiesel from Maggot BSF oil, the experiment's findings can serve as a starting point. in order for biodiesel made from Maggot BSF oil to provide Indonesia with a fresh option for the development of sustainable energy.
