Abstract
The research of gas-fuelled combustion engines using hydrogen or methane require accordingly equipped
test benches which take respect to the higher dangerous of self ignition accidents. This article deals with numerical
calculations of flow in laboratory during simulated leakage of gas-fuel from fuel system of tested engine. The
influences of local suction and influences of roof exhausters on the flow in the laboratory and on the gas propagation
are discussed. Results obtained for hydrogen and for methane are compared. Conclusions for design and
performance of suction devices and test benches are deduced from these results.
