Free surface mixing with heat transfer
- Southern Methodist Univ., Dallas, TX (United States). Mechanical Engineering Dept.
This study investigates the thermal mixing phenomenon as external rocking excitations are applied to a container partially filled with a thermally nonhomogeneous fluid. The aim of this work is to determine the effects of the rocking frequency on thermal mixing in free surface flows. Numerical results show that optimum mixing is achieved while rocking at the wave natural frequency of the tank where the free surface displacements are greatest. At this optimal frequency the strong mixing is observed to be highly concentrated in the area near the free surface. The interest is motivated by the desire to understand the fundamental physics as well as by the importance of current engineering applications in fields such as solar energy (collectors), environmental engineering (ponds, estuaries) aerospace (fuel tanks), electronics (thermal management), manufacturing (sand casting), and air conditioning (residential enclosures).
