Study on the Method for CFX Numerical Simulation of Flow Field in Screw Conveyer of Sand Fracturing Blender

Screw conveyer is an important component of sand fracturing blender.seamless Link of Pro/e and CFX through ANSYS Workbench. Numerical simulation of water flow over the screw conveyer using Realizable k-epsilon turbulence model. From the stress nephogram, velocity nephogram, Velocity vector pofile and micro swirl field pattern, it is seems that the test results can work well under the actual operation condition of field application. This paper also focuses on exploring the method of CFX software simulation when it is used to calculate the internal flow field of the screw type sand transporter. Hence, it is an important guiding significance to the structural optimization design of screw conveyer.
