The laminar three-dimensional boundary layer on a body of revolution at incidence is investigated using two methods. In the first, the standard equations are solved numerically using the Keller box scheme. The second method solves a set of equations, which contain the standard equations, derived from the assumption that crossflow gradients may be important. Since these equations are elliptic in the crossflow plane, an ADI procedure is used for their solution. In regions where there is no crossflow reversal, both methods yield the same results. However, differences appear in regions where the crossflow is not unidirectional. Reasons for this discrepancy are discussed and the relative merits of each procedure identified. Author
