Ansys CFX: Buoyant Flow in a Partitioned Cavity (tutorial)

The goal of this tutorial is to model a buoyancy-driven flow which require the inclusion of gravitational effects.

The model is a 2D partitioned cavity containing air with properties defined at 25°C. The bottom of the cavity is kept at a constant temperature of 75°C, while the top is held constant at 5°C. The cavity is also tilted at an angle of 30 degrees to the horizontal.

The overall approach for solving this problem is to set up a transient simulation to see how the flow develops starting from stationary conditions. Since you are starting from stationary conditions, there is no need to solve a steady-state simulation for use as the initial guess. You will then model the buoyant flow and create a report outlining the results in CFD-Post. You will also create an animation to see changes in temperature with time.
