Abstract
Homogenization is important in modern chemical, pharmaceutical and food industry. The design and optimization for homogenizing units are usually difficult because of lacking enough information about the flow field within the valve. Numerical investigations on flow and pressure fields within a kind of new type homogenizing valve have been conducted using computational fluid dynamics (CFD) software. The study indicates that the new type homogenizing valve can be modeled by CFD and detailed information on high speed flow is available. During the process on numerical simulation, finite-volume technique and RNG k-ε turbulence model are present. Through numerical results, mechanical stresses, high shear rates in small valve region and those phenomena that could not be easily determined experimentally can be reached.
