Oxy-hydrogen gas is a mixture of hydrogen and oxygen gas in 2:1 molar proportion. Oxy-hydrogen gas can be easily and economically produced from electrolysis of water by using dry cell electrolysers. Oxy-hydrogen gas is one of the alternative fuel options which can replace conventional fossil fuels like gasoline, diesel, etc., because of its high-octane number (>130) and moderate calorific value (21.4 MJ/kg). Current research work consists of both experimental and simulation parts. Experiments focussed on studying the performance and emission characteristics of spark ignition engine fuelled with gasoline (petrol) and dual fuel (gasoline + Oxy-hydrogen) mixture at variable load and constant speed condition with three different oxy-hydrogen flow rates. Comparative findings suggest that NOx emission and brake thermal efficiency increased by 1.75% and 800 PPM, respectively, at full load and at a flow rate of 1.54 lit/min. Carbon monoxide emission dropped by 0.25% at full load and at a flow rate of 1.54 lit/min. A two-zonequasi dimensional modelling of spark ignition engine was carried out in order to understand the combustion process efficiently. The predicted values accord well with the experimental data, with just a small variance. Commercially available software MATLAB R2021a is used to develop code for the engine simulation.

Regenerative cooling technology is the most widely used cooling technology in liquid rocket engines, and flow distribution is very important for regenerative cooling heat transfer. In this work, the flow distribution characteristics of Z -type parallel channels were studied through numerical simulation, and the effects of flow area ratio, inlet header shape, and inlet aspect ratio were analyzed. Results showed that changing the inlet cooling header can improve the uniform distribution of flow rate effectively. The nonuniformity coefficient and fuel temperature varied with change in the flow area ratio, inlet header shape, and inlet aspect ratio. The maximum temperature of the wall decreased from 1334.52 K to 1220.61 K when the flow area ratio was changed from 1 to 0.25. An appropriate decrement in the inlet header shape was beneficial to the uniform flow distribution. The inlet aspect ratio should be reduced properly to ensure that each channel experiences similar pressure drop. This research has a certain reference value for the structural design of regenerative cooling channels.
