The optimize design of inlet pipe of hydroclone's structural parameter and dimension

We use Fluent software to analyze the tangential velocity, radial velocity, total pressure, and trajectory of flow of traditional unilateralism column inlet pipe and bidirectional symmetrical radial rectangular inlet pipe. And we use the unidimensional ratio of middle to outside law based on TD Hatty mathematical model to optimize the inlet pipe dimension of cyclone. The research results have provided the powerful theory support for the predecessor experiment. At the same time the research technique proposed in this paper can also be profited by researchers.
