Two Methods to Improve the Efficiency of Supersonic Flow Simulation on Unstructured Grids
Fluids, 2022 The paper presents two methods to improve the efficiency of supersonic flow simulation using arbitrarily shaped unstructured grids. The first method promotes increasing the numerical solution convergence rate and is based on the geometric multigrid ...

Journal of Physics: Conference Series, 2021 Abstract This paper presents numerical modelling of a thermally stratified energy source’s effect on the supersonic flow past a body “double-wedge - plate”. A multiple generation of the Richtmyer-Meshkov instabilities was obtained. These instabilities cause almost complete destruction of the bow shock front inside the source area and ...

Aerodynamic Layout Designs Using of Microflaps for Flow Control of a Supersonic Finned Projectile
Xibei Gongye Daxue Xuebao, 2019 In this paper, the flow control system consists of some small microflaps located between the rear fins of the projectile. These microflaps can alter the flow field in the finned region of the projectile resulting in asymmetric pressure distribution and ...

IOP Conference Series: Materials Science and Engineering, 2017 This paper presents a numerical investigation on the three-dimensional interaction between two bow shock waves in two environments, i.e. ground high-enthalpy wind tunnel test and real space flight, using Fluent 15.0. The first bow shock wave, also called induced shock wave, which is generated by the leading edge of a hypersonic vehicle.

Aerodynamic Interference on Finned Slender Body [PDF]
, 2016 Aerodynamic interference can occur between high-speed slender bodies when in close proximity. A complex flowfield develops where shock and expansion waves from a generator body impinge upon the adjacent receiver body and modify its aerodynamic ...

Computational Hypersonic Aerodynamics with Emphasis on Earth Reentry Capsules
INCAS Bulletin, 2016 The temperature in the front region of a hypersonic vehicle nose can be extremely high, for example, reaching approximately 11 000 K at a Mach number of 36 (Apollo reentry) due to the bow shock wave.
