Abstract
The flight of the Stardust descent capsule is examined. The possibility of simplified calculation of the capsule flow is studied using the perfect gas model when varying the specific heat ratio in the NERAT-2D software. This assumption makes it possible to quickly obtain the accurate flow pattern over a certain altitude range, but often it underestimates the heat flux to the capsule surface.
期刊介绍:
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
