Magnetohydrodynamics and Aerodynamic Heating

Parallel Computation in Hypersonic Aerodynamic Heating Problem

A parallel computational fluid dynamics code has been developed for the study of aerodynamic heating problem in hypersonic flows. The code employs the 3D Navier-Stokes equations as the basic governing equations to simulate the laminar hypersonic flow. The cell centered finite volume method based on structured grid is applied for spatial discretization. The AUSMPW+ scheme is used for the invisci...

!calculating Aerodynamic Heating on Sounding Rocket Tangent Ogive Noses

A method is presented for calculating the aerodynamic heating and shear stresses at the wall for tangent ogive' noses that are slender enough to maintain an attached nose shock through that. portion of flight duringwhich heat transfer from' the botundary layer to the wall is significant. The lower entropy of the attached nose shock combined with the inclusion of the streamwise pressure gradient...

Dual strings and magnetohydrodynamics

We investigate whether dual strings could be solutions of the magnetohydrodynamics equations in the limit of infinite conductivity. We find that the induction equation is satisfied, and we discuss the Navier-Stokes equation (without viscosity) with the Lorentz force included. We argue that the dual string equations (with a non-universal maximum velocity) should describe the large scale motion o...

Thermo-viscopiastic Analysis of Hypersonic Structures Subjected to Severe Aerodynamic Heating

An Approximate Engineering Method for Aerodynamic Heating Solution around Blunt Body Nose

This paper is devoted to predict laminar and turbulent heating rates around blunt re-entry spacecraft at hypersonic conditions. Heating calculation of a hypersonic body is normally performed during the critical part of its flight trajectory. The procedure is of an inverse method, where a shock wave is assumed, and the body shape that supports this shock, as well as the flowfield between the sho...
