Hi,

I am working on cryogenic combustion of hydrogen for CUS rocket engines.
I have been trying this simulation since last 3 months but either i am not getting proper pressure rise in the chamber which should be around 60 bar or the velocity get too high.
Typical massflowrates for single element injector is
LOX : 200 g/s
GH2 : 34 g/s.
For H2-O2 engines minimum length required is
L* : 0.85 m.(it is characteristic length not length)

For signle element the following dimensions can be used
Throat Dia : 13mm
Contraction ratio : 2.5 t ....etc

Hydrogen use in internal combustion Engines



OBJECTIVES
At the completion of this module, the technician will understand:
the combustive properties of hydrogen that relate to its use as a combustive fuel
the air/fuel ratio of hydrogen fuel mixtures and how it compares to other fuels
the types of pre-ignition problems encountered in a hydrogen internal combustion engine and their solutions
the type of ignition systems that may be used with hydrogen internal combustion engine ....etc

ABSTRACT
Since two-three decades, hydrogen has been identified as a versatile potential fuel competent to the conventional fuel such as gasoline. In order to implement it fully and to develop the combustion based power devices which may supply much higher energy density than others, the understanding of hydrogen air combustion mechanism is very essential. In this seminars, Computational Fluid Dynamics (CFD) based numerical simulations have been performed to study the combustion of non-premixed hydrogen-a ....etc

hydrogen fuel in internal combustion engine seminar pdf

Abstract

A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine.Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles (which use electrochemical conversion of hydrogen rather than combustion); the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered internal combustion engine. ....etc
