Temperature measurement experiments with an intake port model and analysis of heat transfer phenomena were carried out to obtain the fundamental information on constructing physical model that expressed heat transfer phenomena in an engine intake system. Temperature measurement experiments on steady air flow were done, and shape inside the intake port model, heating temperature of the intake port model, mass flow rate of air, and the development conditions of the velocity boundary layer and the thermal boundary layer were changed as experiment parameters. As the results, it was clear that the change of inside shape and heating temperature had little influence to the change of Nusselt number but the development condition of the velocity and thermal boundary layer had great influence. And the equations that expressed the Nusselt number with Reynolds number and Graetz number in each case that the velocity and thermal boundary layer were developed simultaneously and individually were obtained.
