Choked Jet KW - Subsonic KW - Transonic KW - SST K-??turbulence model DO - N2 - In the following paper, the effects of a choked jet exhausted from the base of a non-lifting body on its total and base drags at sub-sonic and transonic regimes has been numerically investigated. Having surveyed the results of some turbulence models and after comparing with experimental results, an appropriate turbulence model i.e. SST K-?, has been chosen and this model has been used in the subsequent analysis. The analysis have been conducted in the free stream Mach number range of 0.4 UR - https://jast.ias.ir/article_51585.html L1 - https://jast.ias.ir/article_51585_61a0b716cff7a752aed8641eba9932f3.pdf ER -
