Thermo-fluid-structural Analysis of a Globe Valve

Abstract

This work presents a multiphysics thermo-fluid-structural analysis of a globe valve, aiming to evaluate the behavior of its components subjected to thermal and pressure loading under different flow conditions. Initially, a fluid dynamics (CFD) analysis was performed in Fluent to obtain the velocity and pressure fields of the flow. Subsequently, a steady-state thermal analysis was performed to obtain the temperature fields. The pressure and temperature fields obtained were used as boundary conditions for a structural analysis. This work allowed us to obtain the stresses and displacements in the valve components and establish a correlation between the operating conditions and the structural behavior of the valve.
