Question

Why ignition delay is is reducing when fuel quantity increases

Answer 1

Answer:

hy mate!

Explanation:

increase in fuel temperature would reduce both physical and chemical delay period.

Information on the ignition delay times can be attempted to be obtained experimentally or computationally. As far as the experimental data are concerned, although there is a considerable amount of measured data on ignition delay times, the number of experimental investigations on hydrogen and hydrogen-containing fuels under gas turbine combustion–relevant conditions is rather limited. As far as the chemical kinetics calculations are concerned, the GRI-Mech 3.0 detailed mechanism, which is optimized for methane and natural gas, and universally used in kinetic calculations concerning such fuels, is quite often.
