Mixed Convection in a Lid-Driven Cavity
Problem description:

The 2D model consists of a 10cm × 10cm square cavity filled with air.

Properties of air:
Density dependence on temperature is defined using Boussinesq approximation: 𝜌=𝜌0[1−𝛽(𝑇−𝑇0)] 𝜌0=1.1405 𝑘𝑔𝑚3⁄,𝛽=0.00344827𝐾−1,𝑇0=290𝐾 𝜇=1.7894×10−5𝑘𝑔𝑚𝑠⁄

Boundary conditions:
Hot wall = 305K and no-slip
Cold wall = 290K and no-slip
Bottom wall = insulated and no-slip
Top wall = insulated and velocity of top wall (U)= 0.01m/s (you may change this velocity as per your wish)

Task:

Perform steady-state simulation in Ansys Fluent.

Plot the following:
1. Horizontal and vertical centerline velocities,
2. Velocity contours,
3. Temperature contours,
4. Temperature variation at the top wall
5. Show the changes that you observe when the termination criterion for all is changed to 10-6.
6. Show the changes in temperature plot at the top wall when the mesh size is increased from 100×100 to 300×300.
