Numerical Simulation on Flow Patterns in Reversed Z Annular Homogenizing Valve
Homogenization plays an important role in modern chemical, pharmaceutical and food industry. The design and optimization for homogenizing units are often restrained because of lacking enough information about the flow field within the valve. Numerical investigations on flow and pressure fields within a reversed z annular homogenizing valve have been conducted using computational fluid dynamics (CFD) software. The research indicates that reversed z annular homogenizing valve can be modeled by CFD and detailed information on high speed flow is available. During the process of numerical simulation, finite-volume technique and RNG k-e turbulence model are used. 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.
