A Simplified Design Approach for High-Speed Wind Tunnels. Part-I.I: Optimized Design of Settling Chamber and Inlet Nozzle

Abstract

This study was carried out after the initial divergent nozzle contours of the high-speed wind tunnel inlet nozzle were designed in [1]. The goal of the study is to design a suitable and simplified inlet section (settling chamber, C-D nozzle, and test section) of the supersonic wind tunnel prototype. At first, an optimized design for the settling chamber was created after which the settling chamber could be used for any planned Mach configuration (1.5≤M≤3). In the next step, three different designs for the inlet section of the wind tunnel were created and a suitable design for the future manufacturing of the inlet section was selected with the help of the numerical simulations.
