A fully implicit solution technique is applied to study the unsteady flow characteristics including surface heating and cooling effects of an infinite circular cylinder at a Reynolds number of 100. The fluid flow problem is governed by the Boussinesq approximation of the Navier-Stokes equations. The equations in the finite-difference form are linearized using Newton’s method and the resulting system of equations including the boundary conditions are solved simultaneously using a direct solution technique. In a previous paper, the solution technique was presented and results (coarse grid) were discussed. Here, results are presented for higher grid densities, different boundary conditions, and various angles between the freestream velocity vector and the gravitational acceleration vector.
