Abstract

Renewable energy is renewable and non-polluting energy. One of the new renewable energies is wind, Indonesia itself has an average wind speed of around 3-6 m/s. Wind turbines are tools used to convert wind energy into electrical energy, small-scale wind turbines are wind turbines that have a maximum output power of no more than 500 watts. There are several components in a wind turbine such as generators, fins, controllers, data loggers, batteries and blades. One of the important components in a wind turbine is the blade because the blade is the component that is directly facing the wind. If what is designed is an inverse taper type blade which has a widening shape towards the end by applying the cross sectional shape of the NACA 6412 airfoil. The performance test of the blade is carried out for 3 days with the highest wind speed data acquisition of 8.12 m/s at 13:00 noon and electric power the highest obtained was 136.53 watts at 13:00 noon

Abstract

Wind power plant is a new renewable energy, power plant that utilizes wind turbine rotation to convert wind energy into electrical energy. One of the modifications to the wind turbine that is done is to vary the number of blades. The results of variations in the number of blades are expected to increase the efficiency of wind turbines at certain speeds. In this research, we will vary the number of blades 3, 4 and 5 with an AG 12 airfoil assisted by the Q-Blade application for simulation and find out the results of calculations in graphical form. Variations are made at a minimum wind speed of 2 m/s to a maximum wind speed of 12 m/s. With a planned power coating of 500 watts assuming a turbine rotation of 400 rpm, using a horizontal axis wind turbine (TASH). With a minimum wind speed of 2 m/s, the variations in the number of blades 3, 4 and 5 have not been able to generate power because the turbine rotation factor is too fast at low wind speeds, while at a maximum wind speed of 12 m/s the power generated by the three blade variations 3, 4, and 5 are able to meet the planned power capacity of 500 watts. The highest efficiency is obtained in the variation of blade 4 with 0.453 at wind speed 8 with a power of 300.37 watts, then 0.37 in the variation of 3 blades at a speed of 7 m/s with a power of 164.28 watts, in the variation of blade 5 the highest efficiency is in the figure is 0.29 at a wind speed of 10 m/s with a power of 409.14 watts.

Abstract

Reduction of cylinder surface resistance can be accomplished by modifying roughness. The surface roughness structure is one of the important parameters which greatly affects the flow of fluid through the cylinder surface. Fluid flow forms a vortex flow pattern with certain characteristics. Therefore, this study aims to analyze the characteristics and effects of fluid flow through the rough surface of the outer wall of the pipe with visualization using Particle Image Velocity (PIV). This research was conducted experimentally at the Faculty of Engineering, UHAMKA. The pipe surface roughness values varied were 0.648 µm and 1.699 µm. The length of the pipe used is 20 cm with a diameter of 2 inches. Measurements are made from the center of the pipe to a distance of 0.16 m. The results show that the surface roughness of the cylinder pipe affects the fluid flow characteristics where the formation of eddies is caused by the addition of the roughness value. The rougher the pipe surface is, the farther the vortex formation will be. The vortex formation closest to the pipe is a pipe with a roughness value of 0.648 µm at a distance of 0.04 m.

Abstract

Shell and Tube Heat Exchanger (STHX) is very important for its use in the industrial world which can support the continuity and success of the entire network process. Various kinds of research have been carried out to increase the heat transfer coefficient and effectiveness of Shell and Tube Heat Exchangers (STHX) both experimentally and by simulation. This research examines the increase in heat change coefficient and effectiveness of STHX with variations in baffle angles of 0°, 10°, and 20° with fluid mass flow rates of 2, 4, and 6 kg/s. As a result, STHX with a baffle angle of 0° has the largest heat change coefficient value than STHX with a baffle angle of 10° and 20° both during experiment and simulation, values ​​ranging from 4218 W/m²C and 4226 W/m²C at a baffle angle of 0° when the fluid flow rate is increased to 6 kg/s. Keywords: Shell and Tube Heat Exchanger, baffle angle configuration, double segmental baffle, total heat transfer coefficient, effectiveness, CFD (Computational Fluid Dynamics).

Abstract

The growing demand for air conditioning systems has driven research into alternative applications, such as seawater desalination. This study evaluates the performance of a modified window air conditioner (WAC) integrated with a vortex generator for desalination. Experiments were conducted using R410A refrigerant under four conditions: closed container (CC), without vortex (WV), connected vortex (CV), and separated vortex (SV). Seawater was heated via the condenser to 55–60°C, controlled by a thermostat, and data was collected every five minutes over eight hours. The thermodynamic properties of R410A were analyzed using Refprop software to determine refrigeration effect (RE), compression work (CW), and coefficient of performance (COP). Results indicate that the SV configuration achieved the highest evaporation rate (5.01 kg) but led to a lower COP (3.91) due to increased condenser temperature and compressor workload. Conversely, CC yielded the highest COP (5.08) by stabilizing the evaporator air temperature and reducing compressor effort. These findings suggest that vortex generators enhance evaporation rates but reduce system efficiency. Further research is needed to optimize vortex generator configurations to improve desalination efficiency while minimizing COP reduction.

Abstract

The utilization of water resources as renewable energy through waterwheels presents an environmentally friendly alternative, however, its efficiency requires improvement through technological modification. This research investigates two design modifications: a 45° Angle Cap (AC) and a Water-Filled Angle Cap (WFAC), in comparison with a waterwheel without a Cap (WC). Experiments were conducted at discharges from 1 to 10 m³/h with a constant torque load of 0.05 N-m. The highest efficiency of 57.08% was achieved in the AC 45° configuration at 1 m³/h, generating 1.09 watts of power, while the WFAC 45° yielded the highest power output of 2.88 watts at 10 m³/h with an efficiency of 14.50%. Although increasing discharge generally led to higher power input, it was accompanied by a decrease in efficiency across all configurations. Among all three variations, WFAC 45° demonstrated superior performance at higher discharges, indicating its potential for enhancing the power and efficiency of overshot waterwheels.

Abstract

The crisis of clean water availability has become increasingly critical due to rapid population growth and environmental degradation. One strategic approach to address this challenge is to implement seawater desalination, which provides an abundant, sustainable water source. However, conventional methods remain limited in terms of energy efficiency. This study aims to analyze the effect of pressure and temperature variations on the performance of a large-capacity desalination reactor with an 8000-liter tank. Two configurations were experimentally tested: (1) an air-circulation system that relies on static heating assisted by an axial fan to enhance convection, and (2) a sealed system operating under low-pressure conditions to reduce the boiling point of water, equipped with active hot-water circulation. Data collection was carried out over 27 hours of operation, with the observed parameters including water temperature, partial pressure, relative humidity, and evaporation volume. The experimental results showed that the sealed configuration delivered superior performance, with an evaporation rate 16.64% higher than that of the air-circulation variant. The volume of water successfully evaporated in the sealed system reached 20.12 liters, whereas in the air-circulation system it was only 17.25 liters. This increase in efficiency is attributed to the pressure-reduction effect, which enhances the vapor pressure difference while facilitating uniform heat distribution through active water circulation. This study emphasizes that controlling pressure and temperature is key to improving the effectiveness of the desalination process, thereby supporting the Development of more energy-efficient and sustainable clean water supply technologies.
