TRANSIENT MIXED CONVECTION IN A VERTICAL PIPE FLOW WITH INLET TEMPERATURE STEP
Аннотация
A numerical study is described for the transient laminar combined free and forced convection in a vertical downward pipe flow. The situations investigated in this paper involve the case of a fixed flow rate with constant temperature at the entrance of the duct, then a sudden change of the fluid temperature is imposed in the upflow. The cases of positive and negative steps are studied. The comparison of these two situations shows a strong difference on the streamwise velocity profile and the wall temperature.
