FLOW AND TRANSIENT TEMPERATURE FIELD ESTIMATION IN A PRESSURE VESSEL

Abstract

In this study numerical analysis of fluid flow in a pressure vessel, having annular flow paths, is presented using fmite volume scheme. The geometrical dimensions of vessel simulate to those of pressurized water reactor (PWR). Typical flow path and geometry is encountered in many applications like in heat exchangers, power plants and pressure vessels. Determinations of flow and temperature field and the change of thermal characteristics with the inlet water are of particular interest for design and safety of the vessel. Present study involves developing computer code for obtaining flow field for two-dimensional flow model of actual problem, where in fluid flow from the bottom of the vessel upwards and gets distributed through different flow paths and fluid after reaching a pre-defined zone .loins with large pool. The present problem has been solved by a finite volume method. The solution methodology involves a semi-implicit iterative algorithm (SIMPLE), along with PVM formulation. The typical computed results for flow and heat transfer characteristics are presented
