摘要

本文利用Ansys/Fluent学术版软件对高超声速飞行器进气道无粘流动进行了数值模拟。主要目标是应用网格收敛方法，考虑到具有两个入口坡道的通用高超声速飞行器几何形状，能够在35公里高度和马赫数7飞行。通过构建三个网格进行分析。从一个初始的未细化网格开始，元素的数量增加了一个乘法因子，因此，在感兴趣的点上进行某些流动特性的变化分析。收稿日期:2023年5月29日。收稿日期:2023年7月5日

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.

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.
