Abstract

To maintain ideal working conditions by removing heat, a particular technique must be applied. This research examines how nanofluids affect computer cooling microchannel heating devices. The experiment's working fluids are 25% Therminol-55 and 75% sprinkling water. The mixture contains silicon carbide (SiC), titanium oxide (TiO2), and zinc oxide (ZnO) nanoparticles. It includes 0.25% to 1.5% nanoparticles and flows at 0.025 to 0.080 kg/s at 25°C to 40°C. Central processing unit temperature, heat transfer rate, pressure losses, and pumping power have been examined. SiC-THERMINOL/SPRINKLING WATER at 1.5% concentration and 0.080 kg/s had a 9% lower temperature and 31% larger heat transfer coefficient than the base fluid. SiC-TL/SW has the highest pressure decrease and pumping force power compared to TiO2-TL/SW. Because nanofluid beats basic fluid in computer cooling, a little increase in pumping force power and pressure reduction may be tolerated. [ABSTRACT FROM AUTHOR]

Abstract

Due to the high prospective of rice bran oil, it can be used as a resource for biodiesel production. This study aims to produce high-quality rice bran biodiesel through enzymatic transesterification using lipase enzyme. The fuel properties are tested with standard protocols. Three explicit blends B20, B40, and B40 on v/v basis are prepared for the test purpose. With the CI engine test, the performance characteristics brake thermal efficiency and brake specific fuel consumption are arrived and compared with pure diesel. The emissions of CO, NOx, and HC are also analyzed. Test outcomes uncovered that the blend with lower biodiesel content performed well in the engine with brought down CO, HC and NOx outflows. In any case, with the higher biodiesel concentrations, there was a significant increment in the emission range. By and large, b20 and b40 blend brought about improved performance with limited emissions and can be used in an unmodified diesel engine. [ABSTRACT FROM AUTHOR]

Abstract

Major research is focused on fuel consumption and emission reduction in the past few years. There is growing interest on alternative fuels due to volatile fossil fuel price and depletion. In many applications like Transportation, Power generation, Marine applications etc., diesel Engines are being used as a major source. During last century, the uses of fossil resources are increasing due to significant growth of population and change in life style. This causes crises of fossil fuel depletion For the diesel engines there is an urgent need for suitable alternative fuels. In this work we will examine the use of diesel-wheat germ oil in diesel four stroke engine. With diesel and different blends of wheat germ biodiesel, additionally the efforts to reduce NOx emission by developing Catalytic converter device for a diesel engine fuelled with diesel and wheat germ biodiesel fuel are discussed. Catalytic converter is vital after treatment technology attempted in this work to simultaneous control of NOx, HC, and PM emissions. The experiment was conducted on a 1500rpm, four stroke, diesel engine with single cylinder which is water cooled. an attempt will be made to analyze the performance and emission characteristics of a diesel engine.
