If. Muzafarov et al., NUMERICAL-SIMULATION OF THE FLOW OVER A BODY FLYING THROUGH A THERMALIN A STRATIFIED ATMOSPHERE, Computers & fluids, 23(2), 1994, pp. 295-304
The three-dimensional supersonic viscous flow over a blunted body flyi
ng horizontally through a cloud of hot gas (a thermal) is studied nume
rically. It is assumed that the cloud was formed as the result of a po
werful explosion in the Earth's atmosphere. Consideration is given to
the late stage of the explosion, corresponding to the vortex ring form
ation time. A complete problem is unstable. However, the air flow near
the body at every point of the flight trajectory can be considered as
a quasi-stationary flow, in view of the fact that the ratio of the ch
aracteristic time scale in the shock layer to the thermal characterist
ic time scale is 10(-5). The aerodynamic and heat transfer characteris
tics of the flying body are studied.
