Equations to describe heat transfer from burning gas to a combustion chamber have been empirically derived from hydrocarbon combustion engines. Previous research has analyzed the applicability of the equations to hydrogen combustion and showed that they calculate a lower cooling loss than experimental values. By focusing on the gas velocity term in the heat transfer equation and investigating replacement terms to better fit to hydrogen combustion, a new equation including rate of heat release in the gas velocity term is proposed. It is shown that the new equation is more applicable to hydrogen combustion than the widely used Woschni’s equation.
