Abstract In the present study, flow over aerodynamics models is analysed in water channel to understand physics at affordable cost. The visualization setup constructed analyse analogy between Froude number and Mach various observed. order conduct shallow speed varied from 0.4 m/s 0.6 test section of which will corresponds number, Fr= 2. results be finally validated wind tunnel M=2. velocity can...

In this paper, we investigate steady inviscid compressible flows with radial symmetry in an annulus. The major concerns are transonic or without shocks. One of the main motivations is to elucidate role played by angular velocity structure flows. We give a complete classification flow patterns terms boundary conditions at inner and outer circle. Due nonzero velocity, many new will appear. There ...
