Abstract : The viscous decay of solid body rotation in a circular two-dimensional container is studied using a vorticity-stream-function finite-difference scheme. A comparison is made with the well known analytic solution to determine the accuracy of several finite difference expressions for the wall vorticity. The most accurate results are obtained with a first order scheme that conserves the net integrated vorticity. (Author)
