The algebraic eddy viscosity model of Cebeci and Smith has been modified to account for wall roughness by incorporating a suggestion of Rotta. The boundary-layer equations are solved, with this model, by the accurate and efficient Keller Box scheme for a wide variety of experimental configurations. These include adverse, zero and favorable pressure gradients, and roughness elements that approach the upper limits of Rotta's model. Comparison of calculated and measured values of skin friction and integral thickness confirms the applicability of the procedure for all cases presented.
