| Abstract: | The vapor compression distillation device is the key device to the regeneration and closed-circuit circulation of water in the space station. The lobed rotor compressor as the core equipment in the vapor compression distillation device plays a vital role in the performance of the vapor compression distillation device. Reviewing the relevant literatures,the rotor profiles of the lobed rotor compressor were improved,and 2D finite element modal was established. And a transient CFD numerical simulation was performed for a lobed rotor compressor in this work by means of dynamic mesh technique. The varying tendencies of mass flow rate,the velocity vector and static pressure distribution of the lobed rotor compressor were obtained and analyzed. |
