The random choice method has now been shown to be successfully extendible from the original one‐dimensional unsteady formulation to inert high‐speed flow fields which are steady and two‐dimensional using Cartesian, axisymmetric and Lagrangian formulations. This paper deals with the description of a new implementation of the random choice method formulated for natural co‐ordinates based on streamlines and normals. Comparisons between theoretical and computed results for several different physical configurations are presented.
