Study of Transient Heat Transfer of Components in Internal Combustion Chamber

The high cycle fatigue (thermal fatigue) is common in engines with high specific power output. In order to get the accurate temperature and heat flux distribution of the components with steep temperature gradients in the combustion chamber, an analytical solution in the case of a semi-infinite solid of constant properties is investigated by employing measured instantaneous heat flux as the boundary conditions. The new method is applied to an engine.
