Dynamic Wall Heat Exchanger
Application ID: 47371
The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave shaped deformation induces a pumping effect similar to the peristaltic pumping that compensates the pressure losses. This model combines the Conjugate Heat Transfer multiphysics coupling for the heat transfer in the solid and the fluid with the Moving Mesh interface to handle the wall and channel deformation. A first stationary study models the static configuration and the second time-dependent study computes the dynamic behavior.
