Electromagnetic Reduction of Plasma Density During Atmospheric Reentry and Hypersonic Flights

Atmospheric Reentry Modeling and Simulation

The analysis, being overpredictivebut simple and fast, was then applied to six other sabot models, as given in Figs. 9 and 10, to examine their relative lifting capability. These sabot models and dimensions were generated by the PRODAS code. These sabots are for both the 120and 105-mm calibers, as provided in Table 2. Note that sabotmodel 3 has four petals insteadof the more common three-petal ...

Numerical Simulation of Weakly Ionized Hypersonic Flow for Reentry Configurations

Numerical simulations of axisymmetric flows over reentry configurations at hypersonic conditions using a Navier-Stokes solver are presented. The Navier-Stokes equations are modified using Park’s two-temperature model to account for thermochemical nonequilibrium and weak ionization effects. The finite-volume method is used to solve the set of differential equations. The code has the capability t...

Hypersonic-Flow Governing Equations with Electromagnetic Fields

The paper deals with the formulation of a consistent set of governing equations apt to describe the physical phenomenology comprising the hypersonic flow field of an ionized gas mixture and the electromagnetic field. The governing equations of the flow field and those of the electromagnetic field are revisited in sequence and differences or similarities with past treatments are pointed out and ...
