【Abstract】 Some analytical solutions of 3-D incompressible potential flow similar to blade channel flow in turbomachines are found. The mathematical expressions of their potential function, velocity vector as well as the S1 and S2 stream surfaces are obtained. More attention is focused on two solutions, which are more similar to the blade channel flow in centrifugal and axial turbomachines. respectively. These solutions can be used to check whether a 3-D numerical method is feasible or not. As an example, the computational results from the Mean Stream Surface Method are compared with one of these analytical solutions, and it is shown that they are of great use for verifying the reliability of 3-D numerical methods.更多还原
