Abstract:

Transition of free convection flow of air over a heated surface is investigated numerically by using a Large Eddy Simulation method. Particularly, we focus on how the transition is affected by the inclination angle of the heated plate facing upward. Special attention is paid to the development of the thermal boundary layer and its process of transition from the laminar to turbulent stages. The results show that the transition occurs early when the plate is moved from its vertical position due to the rapid growth of both the velocity and thermal boundary layers. As a consequence, the critical Grashof number drops and the predicted results have very good agreement with various experimental data available in the literature. Shown below preliminary simulation results of the velocity and temperature fields at an inclination angle of 45.
