WebAug 4, 2024 · Airfoil Analyzer. This Airfoil Analyzer tool is mainly intended to be useful in analyzing and comparing the airfoils' geometrical features and in quick plotting of airfoils . Airfoil Analyzer will be useful in the following the ways, Upto 3 airfoils can be ploted together in the plot area to compare the geometrical features and the similarities ... WebWhen supersonic flow goes over a diamond shaped aerofoil it creates 2 different types of shockwaves, Oblique shock waves and Expansions waves. Oblique shock waves are created when supersonic flow hits sharp pointed object, like a diamond shaped aerofoil. Expansion waves are waves that expand the medium through which they are transmitted.
Supersonic flow over a diamond-shaped airfoil is one of the classic canonical cases for demonstrating the application of shock-expansion theory. As the supersonic flow moves over the airfoil, it encounters both oblique shock waves and expansion waves. Though the flow-field is quite complicated, the shock … See more In this homework, you will learn how to set up and solve a supersonic flow over a diamond-shaped airfoil using the density-based solver in Ansys Fluent.
