INFLUENCE ON CONVECTION HEAT TRANSFER WITH MONOTONOUSLY TIMEINCREASING AND TIME-DECREASING MASS FLUX IN A TUBE

摘要：

Turbulent convection heat transfer with monotonously timeincreasing and time-decreasing mass flux in a tube with consideration of variable thermophysical properties was investigated numerically. The turbulent heat transfer model was based on the equation of eddy shear stress and for unsteady process. The numerical calculations were compared with experimental data. It is shown that turbulent heat transfer model is fitting with the experimental results, and can be used for the unsteady flow in a tube.
