چکیده انگلیسی
The present work contributes to define the domain of validity of two continuum approaches, based on Navier-Stokes (NS) and quasi gas-dynamic (QGD) equations, respectively. Results obtained using each method are compared with those obtained using a direct simulation Monte Carlo (DSMC) method considered as a reference. QGD equations differ from NS ones by the presence of additional dissipative terms. The present paper includes a brief presentation of QGD equations and DSMC procedures used here. The rarefied flow around a perpendicular disk has been considered for a freestream Mach number varying from 2 to 20, a Knudsen number equal to 0.1 and two levels of wall temperature.
