Abstract

In the internal cooling ducts of the gas turbine blades, the rib structure is widely used to enhance convective heat transfer with the flow of coolant passing through the rib surface. This research concentrates on the perforated V-rib with grooved in the cooling channel with a rectangular cross-section. This research analyzes the heat transfer and pressure drop in the rectangular channel with a perforated groove v-rib to provide the cooling blade gas turbine solution. This research was conducted by numerical analysis. Several models were created and analyzed using Solidworks Flow Simulation, a commercial computational fluid dynamics (CFD) based on the finite volume method. Solidworks Flow Simulation Solver to analyze laminar and turbulent flow using the Reynolds averaged Navier-Stokes equation. Using the same transport equations for laminar and turbulent flows provides flexibility. Turbulence in the flow is treated using turbulent kinetic energy (k) and turbulence dissipation rate (ꞷ) using the standard k-ꞷ turbulence model. The Reynolds numbers 2000, 4000, 6000, 8000, 10000,12000,14000. By giving 1000 Watts of heat at the bottom of the channel, the air condition at the inlet temperature is 30 oC and a pressure of 1 atm. In the flow regime of 2000 < Re < 20,000, perforated rib construction significantly increases the Nusselt number compared to no rib. The coefficient of friction for the solid rib configuration is higher than for the rib with holes.

Abstract

Occupational safety and health are the most important factors in work because they can encourage productivity, which leads to the welfare of all parties, both employers and workers. One way to avoid work accidents and health problems for workers is to use personal protective equipment and production equipment that supports the processing of food and beverage ingredients (coffee beans). Coffee is an agricultural commodity that is used as a raw material for the food and beverage industry. In Kuta Rayat Village, Namanteran District, Karo Regency, there are household businesses and MSMEs roasting coffee beans, consisting of 2 to 3 Small and Medium Enterprises (MSMEs). The process of roasting coffee beans is done manually, so businesses still produce it on a small scale. The roasting process is carried out by roasting tubes that are rotated manually by Mr. Muhammad Iksan Ginting, which can cause harm to the health of business actors as well as roasting results that are not optimal. The roasting process is the process of forming the taste and aroma of coffee beans. If the coffee beans have a uniform size, specific gravity, texture, moisture content, and chemical structure, then the roasting process will be relatively easier to control. The reality is that coffee beans are so different that the roasting process is an art and requires as much skill and experience as consumer demands. Therefore, based on the problems encountered, it is necessary to design tools that can support the product production process. Coffee Roasting Machine With Smart Phone Control System 2kg Capacity.

Abstract

Fatigue cracks can occur because the material is unable to withstand the load applied repeatedly. A nonlinear vibroacoustic method was introduced to overcome this problem. This is because this method is one of the best solutions because it is suitable for detecting fatigue cracks which is sensitive enough to detect small cracks. The aim of the research is to determine the effect of laser distance measurements on fatigue crack detection using the vibroacoustic method. Therefore, there are steps or procedures that include test object preparation, tensile testing, dynamic tensile testing, and modal analysis. Three different vibration modes are selected to excite the low frequency modes. The vibroacoustic method is a method based on the propagation of high frequency sound waves in solid structures with low frequency excitation. The trained output signal will be converted from the time domain to the frequency domain supported by the use of MATLAB software. The analysis results show that there is a significant influence on the detection of fatigue cracks in aluminum using the vibration acoustic method. The analyzed data shows that measuring the laser distance will influence the crack detection process. Fatigue cracks can occur because the material is unable to withstand the load applied repeatedly.

Abstract

This study aims to determine the results of the hardness values of castings using silica sand molds on market products and the microstructure contained in the results of various mold castings. Aluminum is often used as a material for making automotive components, machinery, art objects, and household appliances. Aluminum is a lightweight metal that is corrosion resistant. The foundry industry has now developed a lot from metal casting to non-metal casting. One of the metal casting technologies known today is metal casting technology with sand casting, the casting carried out in this study uses sand molds. The materials used in this study include silica sand, bentonite, water, aluminum waste, and the tools used include patterns, melting furnaces, scales, sand paper. In this research, testing, hardness test and microstructure test were carried out. The results of the hardness test on the standard specimen have an average value of 76.33 BHN, the first mold variation specimen has an average value of 63.69 BHN, and the second mold variation specimen has an average value of 63.84 BHN. In the microstructure test, the first variation of the castings had good aluminum dispersion, a high level of porosity, and for the second variation specimen the castings had good aluminum dispersion and low porosity. After seeing the results of the hardness and microstructure tests, it can be explained that the market product has a better value for the test results, this is because the results of the castings use permanent molds, and it can also be seen that the results of the microstructure affect a hardness value of the two results of the bentonite-binding silica sand mold castings.

Abstract

Synthetic lubricants have environment problems because they are difficult to decompose and be-come pollutant materials when disposed into the environment. Therefore, there is an increasing demand for biodegradable lubricants. One of the methods to achieve biodegradability of a lubricant is by using eco-friendly base material and nanoparticles from organic materials as additives, such as nanofibers, cellulose and graphene nanoplatelets. In previous studies, it has been confirmed that applying bacterial cellulose at various volume percentages into polyester (POE) oil has reduced friction and wear of the material up 49%. Other studies also mentioned that the addition of several layers of graphene as an additive to Polyalphaolefin (PAO) oil have decreased the value of the fric-tion coefficient from 0.15 to 0.08. In this study, due to their desirable properties, the bacterial cellu-lose (BC) and graphene nanopartcles were used as additives in polyester (POE) oil. Four types of lubricant specimens with different additive content were prepared for the study. The friction tests were carried out using a reciprocating pin on disk type tribometer at temperatures of 65°±3°C and 27°C. The results indicated improvements in the tribological properties; 60% friction reduction at temperature of 65°±3°C and 66.7% at a temperature of 27°C, with the presence of both BC and graphene in POE compared to those without the additives. In addition, the wear analysis from the results of micro-surface observation of the specimen indicates the reduction of the specific wear rate values as the effect of additives. It is found that the specific wear rate decreased from 6.09×10-6 mm3/N.m to 4.82×10-7 mm3/N.m at 65°±3°C and from 1.57×10-6 mm3/N.m to 2.38×10-7 mm3/N.m at 27°C with the presence of both BC and graphene in POE compared to those without the addi-tives.

Abstract

The turning Machining Process is one of the most commonly used machining processes in the industrial world, both in large-scale industries and small industries (home industries). The turning machining process is a process of changing the shape of the material by removing some of the material in the form of swells. During the machining process, there is an interaction between the tool and the workpiece specimen being cut which results in a change in the cutting force. The value of the cutting force is important information in research, this study aims to see the cutting force during the turning machining process using 2 different types. The research data collection method uses sensor tools, there are three sensors, namely the load cell sensor for cutting force, the photoelectric counter module for rotation (rpm), and the thermocouple for feeding temperature. The research variable used is the rotational speed of rpm starting from 90, 110, 150, and 190 rpm, the depth of cut is 0.3 mm. The cutting force generated on the DCGT insert chisel is 5.94N at 90 rpm, 4.13N at 110 rpm, 2.38N at 150 rpm, and at 190 rpm the DCGT chisel gets a force of 2.03N. Furthermore, the cutting force that occurs on the DCMT insert chisel is 2.94N at 90 rpm, 2.67N at 110 rpm, 2.61N at 150 rpm, and at 190 rpm the DCMT insert chisel gets a force of 2.51N. It can be concluded that the decrease in cutting force is influenced by the amount of rpm used, and the magnitude of the cutting force is due to vibrations that occur in the specimen caused by low rpm.
