Abstract
Forced convection transient heat transfer for helium gas at various periods of exponential increase of heat input to a horizontal plate (ribbon) was theoretically studied. In the theoretical study, transient heat transfer was numerically solved based on a turbulent flow model. The values of numerical solution for surface temperature and heat flux were compared and discussed with authors' previous experimental data. It was clarified that the values of numerical solutions for surface temperature and heat flux at the velocity of 6m/s agree well with the experimental data, though they show some differences at other velocities.
