Experimental and Simulation Study on Gas Explosion in Confined Pipe

Experimental tests on hydrogen-enriched methane were simulated using numerical CFD tool FLACs. In this work, hydrogen concentration ranges between 4 to 8 % v/v was mixed with methane/air to observe the characteristic of flame speed and maximum pressure profile during the gas explosion. Experimenta...
