FREE-SURFACE MIXING WITH HEAT-TRANSFER

This study investigates the thermal miring phenomenon as external rock ing excitations are applied to a container partially filled with a the rmally nonhomogeneous fluid. The aim of this work is to determine the effects of the rocking frequency on thermal mixing in free surface flo ws. Numerical results show that optimum miring is achieved while rocki ng at the wave natural frequency of the tank where the free surface di splacements are greatest. At this optimal frequency the strong mixing is observed to be highly concentrated in the area near the free surfac e.
