齿边浮阀塔内气相流场的数值模拟和分析

         

摘要

A three-dimensional computational fluid dynamics (CFD) model for gas flow through a seffated valve tray was presented.The flow field.as well as the dry-pressure drop of the valve under the full-opening condition was simulated based on the proposed model by using FLUENT 6.0 software.Compared with t11e values of dry-pressure drop in difierent tUrbulent models.the simulated results using RNG κ-ε model are in reasonable agreement with experimental data.indicating that RNG κ-ε modeliS suitable in simulating gas flow through the serrated valve tray.Then the CFD model combining RNG κ-εmodel was used to study the three-dimensional gas flow through the considered serfated valve trav.The simulated results showed that various eddies existed on the serrated valve tray,and both the eddy and the non-eddy areas were nearly equal.The existence of addendum Can decrease the eddy area caused by gas passing through the lateral outlet slots.The size of eddies Call be reduced by optimizing the distance between valyes.
