Abstract:   (1644 Views)
In this study, the conduction and convection modes in heat transfer have been investigated using Moiré deflectometry method. The method is based on the displacement of Moiré fringes due to a refractive index gradient, induced by a temperature gradient. For this, were evaluated Moiré fringe displacements under a temperature gradient on the fluid from up to down by COMSOL Multiphysics software. In this case, just heat conduction mode may be participating in the heat transfer of the fluid. Then, Moiré fringe displacements were determined under a temperature gradient on the fluid from a horizontal side to another horizontal side. In this case, heat transfer in the fluid may be happen through both mods of conduction and convection. The results show that when the heat transfer is directed only through the conduction, the Moré fringe displacements happen on a one direction at any time, but in the case in which both thermal modes are excited, some fluctuation may be observed in the Moiré fringe displacements. In addition, medium thermal response has been study under a temporal periodic condition on the boundaries.
