Numerical Study on a Conducting Wavy Fin in a Rectangular Cavity

The transition of the steady fluid flow in a differently heated cavity with an adiabatic wavy fin installed on its hot wall to the unsteady one under the action of this fin was simulated numerically depending on the geometry of the fin. It was established that the thermal behavior of the fluid in the cavity is greatly dependent on the relative undulation of the fin, and the heat transfer in the cavity increases with increase in the fin-developed heat exchange surface of the cavity.
