DESIGN AND STATIC THERMAL ANALYSIS OF PRESSURE VESSELS WITH VARIOUS MATERIALS USING FEM

Abstract

Stress assessments are required for a great deal of plant components, including the pressure vessel. A pressure vessel is a container designed to store liquids or gases at pressures much higher than the surrounding air. The finite element analysis of pressure vessels with various types of heads that maintain the same cylindrical volume and thickness is the focus of this project. The intended pressure vessel is made for 8 bar of pressure and 24 lit of volume in accordance with ASME standard section VIII, division I. In order to identify the source of the stress concentration zone in each kind of pressure vessel head at the same volume and reasonable pressure, certain end connections are evaluated under FEA. The project's goal is to use Ansys software to analyse various designs and static and thermal data. It finds that elliptical and flat head pressure vessels have lower distributed stresses than other types of heads, making them the preferred choice for most applications. It displays the fundamental construction and uses finite element modelling to analyse pressure vessels made of various materials, such as Nimonic 80A and SA516 Gr70, and with several types of heads under high stress conditions. In this project, we use the Finite Element tool to compute the estimated stresses that occur in cylindrical pressure vessels supported by two saddles under various end connection types. In order to determine the appropriate design and material, static structural analysis and thermal analysis are performed to compute the stresses in the vessel.
