چکیده

Direct methods for solving the generalized Boltzmann equation are advanced by simulating flow past threedimensional immersed bodies in diatomic nitrogen in rotational-translational non-equilibrium. The simulations are performed by solving the entire domain with the generalized Boltzmann equation using a solver based upon the conservative discrete ordinates method of Tcheremissine. Coarse and refined grid solutions are generated for three axisymmetric three-dimensional bodies – blunt body, bicone, and hollow flared cylinder. The solutions are compared and a parallel implementation is developed to enable further levels of grid refinement.

Numerical Solution of Non-equilibrium Hypersonic Flows of Diatomic Gases Using the Generalized Boltzmann Equation

The paper describes the methodology for computing hypersonic non-equilibrium shock wave flows of diatomic gases using the Generalized Boltzmann Equation (GBE) including both the vibrational translational (VT) and rotational translational (RT) relaxations. For the VT relaxation, GBE is always solved. For the RT relaxation, two approaches are employed. In the first approach, for the RT relaxation...

Approximate Viscous Shock-Layer Analysis of Axisymmetric Bodies in Perfect Gas Hypersonic Flow

In this paper, an approximate axisymmetric method is developed which can reliably calculate fully viscous hypersonic flow over blunt-nosed bodies. In this method, a Maslen’s second-order pressure expression is used instead of the normal momentum equation. The combination of Maslen’s second-order pressure expression and viscous shock layer equations is developed to accurately and efficiently com...

Laminar and Turbulent Aero Heating Predictions over Blunt Body in Hypersonic Flow

In the present work, an engineering method is developed to predict laminar and turbulent heating-rate solutions for blunt reentry spacecraft at hypersonic conditions. The calculation of aerodynamic heating around blunt bodies requires alternative solution of inviscid flow field around the hypersonic bodies. In this paper, the procedure is of an inverse nature, that is, a shock wave is assumed a...

Multiple temperature kinetic model and gas-kinetic method for hypersonic non-equilibrium flow computations

It is well known that for increasingly rarefied flowfields, the predictions from continuum formulation, such as the Navier–Stokes equations lose accuracy. For the high speed diatomic molecular flow in the transitional regime, the inaccuracies are partially attributed to the single temperature approximations in the Navier–Stokes equations. Here, we propose a continuum multiple temperature model ...

Low Rem 3D MHD Hypersonic Equilibrium Flow Using High Order WENO Schemes

We present work on 3D hypersonic laminar flows of air around blunt bodies with applied magnetic fields of various strengths. The air is heated by a shock that can change its thermodynamic properties. We treat the air both as a calorically perfect gas (chemically frozen) and as a real gas in thermodynamic equilibrium. Due to the high temperature the thermodynamic properties of the air are affect...
