Equations to describe heat transfer from burning gas to the combustion chamber wall have been empirically derived from hydrocarbon combustion engines. Previous research by the authors analyzed the applicability of them to hydrogen combustion, and showed that the equations calculate lower cooling loss than experimental values. It was therefore concluded that a new heat transfer equation is necessary to describe cooling loss in hydrogen combustion engines. This research focused on the gas velocity term in the heat transfer equation and investigated new terms to replace it for better fit to hydrogen combustion. A new equation with a gas velocity term including rate of heat release was newly proposed and showed better application to hydrogen combustion compared to the widely used Woschni's equation.
