Аннотация: Based on supercavitation effect, a novel device named Rotational Supercavitating Evaporator (RSCE) has been designed for desalination. In order to improve the performance of RSCE, the optimal design of three-dimensional blade shape is performed by utilizing the empirical formulae which have been validated before. Numerical simulation is then conducted on the supercavitating flow in RSCE with the optimized blade, and the supercavity dimension generated by rotational cavitator is obtained, which is further compared with the above-mentioned empirical formulae obtained by two-dimensional calculations. The results show that the supercavity length obtained by numerical simulation on the optimized blade increases with the increase of radius at first, and then decreases at larger radii, which is much smaller than the result of empirical formula at each radius.
