Abstract
In the present research, highly unsteady flow in curved pipes is numerically studied while significantly varying the Wormersley Number and high Dean Number. The major new method introduced in the paper is the prediction of the flow pressure gradient based on fluid acceleration and on errors in the local mean flow velocity. This improved algorithm increases the efficiency of our calculations by more than an order of magnitude.
