This work presents a computational model of gas flow and hydrogen combustion in a diffusion flame We validate the model using a simple miniature diffusion flame hydride atomizer, in which the H radical distribution was both simulated and determined by two-photon absorption laser-induced fluorescence. A good agreement of the simulations with experi-ments was found. Since the performance of a hydride atomizer can be linked directly to the H radical distribution in the atomizer the presented model is a reliable predictive tool for atomizer optimization as well as for design of new atomizer geometries. The model is based on the open source laminarSMOKE framework and is itself opensource, it can be there-fore leveraged by the scientific community for further theoretical studies on various hydride atomizer.
