Abstract
A numerical model of two-dimensional surface boundary-layer flow based on a non orthogonal coordinate mapping is developed. Results show good agreement with previous computations using conformal mapping techniques for flow over a periodic wavy surface and over an isolated hill. Results are presented for flow over Gaussian hills and valleys and over smooth sloping escarpments. For a 1 in 4 Sine ramp, good agreement is obtained with Freeston's (1974) wind-tunnel measurements.
