“…Condensation phenomena in high-speed flow have been observed in a shock tube by Wegener and Lundquits (1951), who use air of known humidity in the high-pressure compartment and electronically detected the presence of water drops in the flow following the bursting of the diaphragm by the amount of light scatter from the droplets (Pichaimuthu and Swaminathan, 2021). The aim of this study is to come up with a similar medium of design and enhance it in a much more effective shock tube with the materials available in the market and to cause a supersonic flow in the test section.…”

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.

“…Many researchers were interested in the response of the boundary layer to external unsteady fluctuations of the free stream velocity around a mean value because of its numerous applications in science and technology; megnato hydrodynamics (MHD) flow with heat and mass transfer has captivated the interest of many researchers (Manigandan et al , 2021; Pichaimuthu and Swaminathan, 2021). These phenomena can be seen in buoyancy-induced motions in the atmosphere, water bodies and quasi-solid bodies like the earth, among other places (Gunasekar et al , 2022; Brindhadevi et al , 2021).…”

Purpose Chemical reaction effects are added to the governing equation. This paper aims to get the solution by converting the partial differential equation into an ordinary differential equation and solve using a perturbation scheme and applying the boundary conditions. Design/methodology/approach In this paper, the authors discussed the chemical reaction effects of heat and mass transfer on megnato hydro dynamics free convective rotating flow of a visco-elastic incompressible electrically conducting fluid past a vertical porous plate through a porous medium with suction and heat source. The authors analyze the effect of time dependent fluctuating suction on a visco-elastic fluid flow. Findings Using variable parameters of the fluid, the velocity, temperature and concentration of the fluid are analyzed through graphs. Originality/value The velocity profile reduces by increasing the values of thermal Grashof number (Gr), mass Grashof number (Gc) and the magnetic parameter (M). On the other hand, the velocity profile gets increased by increasing the permeability parameter (K). The temperature profile decreases by raising the value of Prandtl number (Pr) and frequency of oscillation parameter (ω). However, the source parameter (S) has the opposite effect on the temperature profile. The concentration profile reduces in all points by raising the chemical reaction parameter Kl, Schmidt number Sc, frequency of oscillation ω and the time t.

“…The jet that exits the nozzle is usually turbulent jets which form a family of free shear flows has its application in the aerospace sector and combustion system (Rathakrishnan, 2019). The development of jet flow can be affected by the nozzle exit shape, initial turbulence level, Reynolds number and aspect ratio (AR) (Pichaimuthu and Swaminathan, 2021). Non-circular jets emerging from the square, triangular, rectangular or elliptical nozzles has shown improved mixing characteristics, jet noise reduction, increased entrainment and faster mean velocity decay along with the central axis of the jet as compared with the jet flow field from circular nozzles (Gutmark and Grinstein, 1999).…”

Purpose The purpose of this study is to understand experimentally the mixing characteristics of a two-stream exhaust system with a supersonic Mach 1.5 primary jet that exits the rectangular C-D nozzle surrounded by a sonic secondary jet from a convergent rectangular nozzle by varying the aspect ratio (AR = 2 and 3) similar to those that can be available for future high-speed commercial aircraft. Design/methodology/approach This paper focuses on the experimental results of effects of AR at various expansion levels of jets issued/delivered from a central rectangular convergent-divergent nozzle of AR 2 and 3 surrounded by a coflow from a convergent rectangular sonic nozzle. The lip thickness of the primary nozzle is 2.2 mm. various nozzle pressure ratios (NPRs) ranging from 2, 3, 3.69 and 4 were chosen for pressure measurements. Findings For all the NPRs, AR 3 had a shorter core than AR 2. Also, AR 3 was found to decay faster in the transition and fully developed zones. The lateral plots show that the AR has an influence on the jet spread. Originality/value The structure of waves existing in the potential core of the rectangular coflow jet along with the major and minor axis planes was visualized by the shadowgraph technique.
