Aerodynamic Design Of Diagonal Impeller And The Blade Design

The main object of this paper is to design a diagonal impeller, which requiressmall size and high rotating speed The first step of design is to solve the radial distribution of parameters at the inlet and outlet of the blade, such as pressure, temperature and velocity. And then, according to the radial distribution, we can design the diagonal impeller blade. Blade elements are defined on a cone, which pass through the blade edge streamline location. At last we test the diagonal impeller, modify the aerodynamic parameter to meet the design requirement.
