A simplified method has been devised for the solution of two-dimensional compressible flows through well-defined passages. This method makes use of plastic cams which automatically set the length-to-width ratio of rectangles formed by streamlines and equipotential lines represented by spring-steel wires. Pressure distributions around four cascades of turbine blades and along the surface of a choked nozzle determined by this method are shown to compare well with experimental results.
