    Abstract:

    In order to study the flow field distribution and variation law of the interaction between oil and screw in the chamber of a single screw press, a physical model of the screw press and the fluid field was established. In Fluent software, k-e model and SIMPLEC solver are used to solve the finite element simulation. The distribution of pressure field and velocity field of oil in the main pressing section is obtained. Through fluid-structure coupling analysis, the stress and deformation of the screw under oil extrusion are obtained, and the location where the screw is prone to large deformation and stress concentration during the pressing process.
