Minimal thrust of the order of few Newton is produced using micro thrusters, which are used for controlling the orientation and trajectory of the satellite or spacecraft. Controlled thrust production of the order of milli Newton is still a challenging task. Green propellants like Hydrogen peroxide are utilized in such applications. The products of this green fuel after decomposition are water in the form of steam and oxygen. The present work involves the simulation of hydrogen peroxide decomposition on silver catalyst which can be used in space propulsion. The simulations are done for flow of 30% hydrogen peroxide concentration when flowing inside a mini channel of size 3.4mm. Helical shaped silver catalyst is positioned inside the tube to enhance the decomposition. The model involves the concentration measurement of the reactants and products and after passing over the catalyst surface. The results will help in choosing the geometry and position of the catalyst to have effective decomposition of the monopropellant.
