Mathematical modeling of gas-liquid flow in microchannels of various geometry under chemical reactions, friction and heat exchange

The authors offer a mathematical description of gas-liquid flow in micro channels of various geometry with the account of chemical reactions, friction and heat exchange and make a comparison of results of calculation of fluid flow in micro channels with the data which were already published. Gas-liquid flows in micro channels of complex geometry with chemical reactions and heat exchange are shown on an example of flow in micro channels of liquid monopropellant micro thruster. Results of calculations of processes of catalytic and thermal decomposition of a hydrazine, hydro- and gas flow in the distributive block, the catalytic reactor and a nozzle, heat exchange processes in the engine chamber, are presented.
