Numerical aspects of finite-element calculations of flow past a sphere
Abstract
The steady axisymmetric isothermal incompressible flow past a sphere in unbounded fluid is investigated for Reynolds numbers in the range 1 to 100. A stream function - vorticity formulation of the flow equations in spherical polar coordinates is used and solved by a Galerkin finite-element method. The drag coefficient is calculated and compared with the results of previous investigations. Plots of the perturbation stream function are given and are used to examine the effect of different boundary conditions far from the sphere.
