Simulation of the flow in a differentially heated rotating fluid annulus

A controlled-volume approach is used to simulate the incompressible flow in a differentially heated uniformly rotating fluid annulus. Pressure and velocities are calculated iteratively at each time-level, yielding a semi-implicit scheme. Buoyancy effects are included by using the Boussinesq approximation. The model is tested against observations of the flow in an annulus with a radial barrier. Differential heating is provided by maintaining the side-walls of the annulus at separate temperatures.
