Numerical Solution of Compressible Steady Flows around the RAE 2822 Airfoil
EPJ Web of Conferences, 2014 The article presents results of a numerical solution of subsonic, transonic and supersonic flows described by the system of Navier-Stokes equations in 2D laminar compressible flows around the RAE 2822 airfoil.

Труды Института системного программирования РАН, 2018 The hybrid method for approximation of advective terms is proposed in order to resolve flows in the wide Mach numbers region. This hybrid method is based on the Kurganov-Tadmor (KT) scheme and projection method PISO (Pressure Implicit with Splitting ...

An experimental study of the influence of spike in supersonic and transonic flows past a hemispheric body [PDF]
FME Transactions, 2022 A strong shock wave during a supersonic flight of a blunt-nosed projectile increases the drag and aerodynamic heating considerably. A spike can be mounted on the nose of the projectile to reduce these effects. Apart from its very existence and its length,

A Unified Asymptotic Theory of Supersonic, Transonic, and Hypersonic Far Fields
Axioms, 2022 The problems of steady, inviscid, isentropic, irrotational supersonic plane flow passing a body with a small thickness ratio was solved by the linearized theory, which is a first approximation at and near the surface but fails at far fields from the body.

A face-based immersed boundary method for compressible flows using a uniform interpolation stencil
Frontiers in Mechanical Engineering, 2022 In this study, an immersed boundary method developed for compressible viscous flows (Ramakrishnan, R., Girdhar, A., & Ghosh, S. (2016). Immersed Boundary Methods for Compressible Laminar Flows) is modified to improve their stability and robustness ...

Entropy Minimization Design Approach of Supersonic Internal Passages
Entropy, 2015 Fluid machinery operating in the supersonic regime unveil avenues towards more compact technology. However, internal supersonic flows are associated with high aerodynamic and thermal penalties, which usually prevent their practical implementation. Indeed,

Engineering Applications of Computational Fluid Mechanics, 2018 The widely used improved delayed detached eddy simulation (IDDES) method is supposed to accurately predict the mean skin friction when it acts as wall-modeled large eddy simulation (WMLES), as claimed by the original authors.

Annular Supersonic Ejector Design and Optimization [PDF]
, 2012 An ejector is a device that entrains a secondary flow into a high speed stream that is generated by expansion of high pressure motive gas [1]. These ejectors can be broadly classified into central ejectors and annular ejectors.

Effects of Inflow Mach Number and Step Height on Supersonic Flows over a Backward-Facing Step
Advances in Mechanical Engineering, 2013 The backward-facing step is practically implicated in many devices, encountering the massive separation flows. In the present study, simulations of supersonic flow over a backward-facing step have been carried out employing both RANS and LES.

A: Universality in Vortex Formation. B: Evaluation of Mach Wave Radiation Mechanisms in a Supersonic Jet [PDF]
, 2000 In this thesis two distinct features of coherent structures are investigated. In Part I a model for the pinch-off process in vortex ring formation is developed.
