GRID CONVERGENCE TEST FOR A BI-DIMENSIONAL HYPERSONIC FLOW SIMULATION
This paper presents a computational simulation of the inviscid flow at the inlet of a hypersonic vehicle, using the academic version of Ansys/Fluent. The main objective is to apply a mesh convergence methodology, considering a generic hypersonic vehicle geometry with two inlet ramps and capable of flying at 35km altitude and Mach number 7. The analysis is performed by constructing three meshes. Starting from an initial unrefined mesh, the number of elements is increased by a multiplication factor, and, thus, the analysis of the variation of certain properties of the flow at points of interest is performed. Received: May 29, 2023Accepted: July 5, 2023
期刊介绍：
The JP Journal of Heat and Mass Transfer publishes peer-reviewed articles in heat and mass transfer which enriches basic ideas in this field and provides applicable tools to its users. Articles both theoretical and experimental in nature covering different aspects in the area of heat and mass transfer such as heat transfer in phase change phenomena, machinery and welding operations, porous media and turbulence are considered. Priority is given to those which employ or generate fundamental techniques useful to promote applications in different disciplines of engineering, electronics, communication systems, environmental sciences and climatology. Because a combination of two or more different technologies in a single device may result into a significant development, the journal extends its scope to include papers with the utility value in electronics and communication system. In this spirit, we are devoting certain number of issues to ‘Mechanical Systems and ICT – Convergence’. Survey articles dealing with certain issues in the context of current developments in heat and mass transfer together with their applications in interdisciplinary topics are also entertained.
