Abstract

Hydrogen release from a high pressure vessel is simulated using a computational fluid dynamic (CFD) code. An existing compressible Euler CFD solver is extended to solve the mixture of fluids together with extra transport equation for hydrogen species concentration. The modifications to the governing equations are presented as well as the discretization with the same techniques as the core solver. The core solver uses an implicit conservative scheme which is based on a finite volume technique for spatial discretization. The mixture of fluids is assumed to obey the ideal gas law and hence pressure, temperature, and density are coupled using the perfect gas equation of state. The code is used to simulate and study an inviscid hydrogen jet exiting a reservoir with initial pressures of 100 and 800 bars. The results obtained for the 100 bars test case are compared with the available data from another numerical simulation. Excellent agreement is observed
