Design and analysis of single and multi-layer pressure vessel

Abstract

This article presents a comprehensive investigation on the design and evaluation of monoblock pressure vessels using computer-aided design (CAD) and computer-aided engineering (CAE) software. Pressure vessels, commonly known as sealed cylindrical shells, are engineered to withstand high internal pressure and enhance structural robustness. The vessels feature a multi-layered structure that incorporates inherent safety mechanisms. They find widespread applications in diverse industrial sectors, including automotive, aeronautics, nuclear power, and biotechnology. This study utilizes established materials such as Steel-s515-gr70, Aluminium Alloy (6061-t6), and Grey Cast Iron to design a pressure vessel configuration comprising multiple layers, which aims to reduce stress and improve the security and longevity of the vessel. The CREO (8.0) software is employed for accurate modeling and optimization of the vessel's geometry, while the ANSYS (2022 R1) software enables static structural analysis to assess its performance under various loading scenarios. By utilizing CAD and CAE tools, this research aims to advance the techniques for designing and analyzing pressure vessels. The combination of pre-existing materials and a complex layered design serves to mitigate stress and enhance the safety and efficiency of the pressure vessel. The findings of this study contribute to the overall understanding of pressure vessel design and analysis, with the ultimate goal of developing pressure vessels that are safer and more efficient in diverse industries.
