TURBULENT BUDGETS IN ROTATING PIPES BY DNS

The budgets for the Reynolds stresses are given for a non-rotating and a rotating pipe at high rotation rates. The data have been obtained by fields generated by direct numerical simulations at Re = 4900. Particular emphasis has been devoted to the near wall region since background rotation modifies the wall structures. These budgets are useful to whom is interested to develop new one-point closure turbulence models for rotating flows.
