Abstract: An intensive literature review is carried for the analysis the high pressure hydrogen jet exiting into the air through different structured orifices. An extensive research has been carried out by various researchers to study the effect of orifice geometry on the structure, development and dispersion of highly under expanded hydrogen jet. The numerical work has been reported in the literature for different shapes of orifices including constant area holes i.e. circular and elliptical openings and enlarging apertures (circular orifice). In the present report numerical compressible jet simulation was carried out using large eddy simulation (LES). The gas was considered as ideal, which was compressed and stored at 100 atm. For treating the convective fluxes Advection Upstream Splitting Method (AUSM) was used. A non variable nozzle opening area was considered and investigated by varying the aspect ratio and alignment of the nozzle and an extensive literature was carried out to understand the characteristics of the jet in relation with the nozzle shape and size and detailed parametric study in terms of mach number, average velocity, RMS velocity, density, pressure, temperature and velocity magnitude which were changing along the centre plane or centre line was conducted and the results have been compared with results available in the literature.
