Abstract

The decline of the world oil reserves is a global crisis for decades to come. The search for renewable energy alternatives is an urgent topic of current research trends. Indonesia has an abundance of energy availability in the form of potential microhydro development. This research is a research of development of new innovative technology in microhydro technology in the form of conversion technique of water flow energy into electric energy using hydro flutter technology. In this research, the development of new tool to convert energy from water flow into electrical energy was developed. A prototype was built that can extract energy from the water stream at times into mechanical energy ready for conversion into electrical energy using the hydro flutter principle of a flexibly mounted free leading edge cantilevered rigid plate. The advantages of the new concept are the simplicity of the design and the ability to clean the system by itself, thereby reducing the maintenance costs.

Abstract

Experimental studies on Fan Coil Unit (FCU) were conducted to investigate heat transfer characteristics due to the addition of Al2O3 nanoparticles. The aims of this study was to reveal the phenomenon of nanofluid particle influences on heat transfer performance indicators. This investigation used tube and fin FCU type with cold fluid is water-Al2O3 nanofluid and hot fluid is ambient air. The cold fluid volume flow rate is 15 lpm and the hot fluid mass flow rate is 0.48 kg/s. The concentration of nanoparticles was 0.1%. The ambient air temperature inlet of FCU is 28 ± 0,50C while the cold fluid temperature entering the FCU is 19 ± 0,50C. In this study the performance parameters on cold fluid with nanoparticles were compared with no nanoparticles. The results showed that the small addition of nanoparticles in cold fluid increased heat transfer in FCU by 9.2%.

Abstract

In this study observed the role of molecular clustering on engine performance produced by hydrous ethanol fuel (95.5% v). The test was performed using variation load for four-cylinder motor. Engine performance is measured using Brake Power Engine load cell type indicator TD 800PM. The engine performance produced by anhydrous ethanol was also tested. The resulting engine performance of both fuels is compared. The results showed that the power produced by hydrous ethanol was slightly higher than that of anhydrous ethanol. The charging effisiency generated by hydrous ethanol is upper than that of anhydrous ethanol.
