Development of cost-effective shock tube based on experimental and numerical analysis

Abstract

Purpose The purpose of the study is to design economical shock tube. It is an instrument used for experimental investigations not only related to shock phenomena but also for the behavior of the material when it is subjected to high-speed flow. The material used here in this shock tube is stainless steel ss304 and aluminum. A shock tube consists of two sections, namely, the driver and the driven. The gas in the driven and driver is filled with atmospheric air and nitrogen, respectively, under the predominant condition. Design/methodology/approach The focus of the study is on the design and fabrication of shock tubes. a shock tube is a research tool to make an aerodynamic test in the presence of high pressure and temperature by generating moving normal shock waves under controlled conditions. Findings The main necessity for instrumentation in the shock tube experiment is to know the velocity of the moving shock wave from which the other parameters can be calculated. the pressure transducers are located in the shock tube in various locations to measure aerodynamic parameters in terms of pressure. Originality/value The main objective of this project work is to make an experimental setup to produce supersonic velocity with the readily available material in the market in a highly safe manner.

Flow of visco elastic fluid through a porous medium with chemical reaction

“…Many transportation processes occur in natural and industrial processes where heat and mass are transferred simultaneously as a result of thermal diffusion and chemical species diffusion. The free convective and mass transfer flow of a viscous fluid through a porous medium has been studied by several researchers (Ramesh et al, 2021;Anand et al, 2021). Krishna and Jyothi (2019) and Das et al (2009) have investigated mass transfer through a porous medium problem.…”
