Transient Convective Heat Transfer to Turbulent Flow from a Flat Plate with Constant Heat Capacity (Numerical Analysis)

Abstract

This paper presents a numerical analysis of transient turbulent heat transfer from a flat plate with a constant heat capacity. A flat plate which was set parallel to a uniform flow was initially at the same temperature as the flow, and the plate was heated stepwise with time. The responses of turbulent heat transfer on the plate were calculated by the Laplace transform and the numerical inversion of the Laplace transform. The variations of a dimensionless wall temperature and a Spalding function were obtained. The relation between the numerical results and the one dimensional heat conduction solution or the quasi-static solution was also obtained
