This study establishes methods to overcome choked-flow and flow-hysteresis problems of Busemann biplane at off-design conditions. Two-dimensional (2-D) analyses of three Busemann-type biplanes have been addressed, using the application of Computational Fluid Dynamics (CFD) code in inviscid flow (Euler) mode. shoes digital printing machine
