Abstract

Water and cooking oil are fluids that we often encounter in our daily lives and are often needed. Water is polar while cooking oil is non-polar, so in uniting the two fluids an emulsifier (Tween 20) is used to mix them. The aim of this research is to combine polar and non-polar fluids. Emulsifier (Tween 20) is used as a polysorbate surfactant (mixing agent) for the two fluids and can mix perfectly. The combined water and oil are mixed using a mixing stirrer with a speed of 100-200 rpm, a temperature of 70⁰C, within 1 hour. To obtain a fluid density value by providing heating from 30⁰C-90⁰C, then inserting it into a 25 ml volumetric flask and weighing it. After mixing, a white hybrid fluid will be produced, and it will separate again when the fluid is at room temperature.

Abstract

This research focuses on developing deflectors to improve the performance of Darrieus turbines, a type of vertical wind turbine known for its efficiency in the conversion of wind energy into mechanical energy. The main objective of this research is to test different deflector shapes to optimize the airflow entering the turbine blades and improve the efficiency and power output of the turbine. In this study, various deflector designs including semicircular, triangular, rectangular, hexagonal, and pentagonal shapes were examined to determine their effectiveness in directing and accelerating airflow to the turbine blades. The research method involved aerodynamic simulations using CFD software. The results showed that the semicircular-shaped deflector provided significant performance improvement compared to the other shapes. These deflectors successfully reduced turbulence and drag, and accelerated the airflow entering the turbine blades, thereby increasing the overall power output of the Darrieus turbine. In addition, the analysis shows that at 17.5, 10.5, and 8.5 m/s calculations, at 8.5 m/s wind speed calculation, the air speed can reach 30.1% with a force of 7.30344 N, and 10.5 m/s speed can reach 24.33% with a force of 11.361 N, and 17.8 m/s wind speed can reach 20.67% with 25.638 N force.

Abstract

The most important parts of a gas power system are the compressor and gas turbine. Compressor performance will naturally decrease due to high ambient temperatures and dirt in the incoming air and make the compressor inefficient. To restore compressor efficiency, it is recommended to clean the compressor using the compressor blade washing method. The purpose of this study was to determine the compressor blade washing procedure used in the PLTG system and determine the parameters tested and analyses their effect on the thermal efficiency of the PLTG. This study was conducted on a PLTG unit operating at a load of 120 MW or 50% of the installed capacity, with research stages including data collection, calculation of the gas turbine heat rate, calculation of the thermal efficiency of the PLTG cycle and calculation of compressor efficiency. From the implementation of the compressor blade washing carried out, there was an increase in compressor efficiency of 2.62% and after the compressor blade washing caused a decrease in the heat rate of 853 kJ / kWh, so that there was an increase in the thermal efficiency of the PLTG of 1.74%.
