Experimental Investigations on a Diesel Engine Fueled with Biodiesel Blends and Diethyl Ether as an Additive
Abstract: Blends of bio-diesel (or diesel) are fueled for engines (diesel) though direct injection by a single cylinder at various (or multiple) propagations. The determination of the emissive power and the performance of the engine is done. The emission of the NOx is considerably high when compared to the diesel fuel operation (considering all the blends). Blends are added with the diethyl-ether at various proportions. Reduction of NOx emission at the …

Kalina Cycle Thermal Analysis Using Heat Recovery Process
Abstract: It is not possible to measure very high temperature with help of physical temperature measuring probes, so in order to get temperature of flue gases, inverse heat transfer theory is applied. Measuring the temperature on outside wall of pipe from which flue gases are going out, it is possible to get calculated values of flue gases (which is not possible to get with physical probe) using inverse heat transfer analysis. …
