| 1 | Kinetic comparative study on aerodynamic characteristics of hypersonic reentry vehicle from near-continuous flow to free molecular flow显示文摘A scaled model of the X38-like configuration was simulated under hypersonic conditions for the direct simulation Monte Carlo method and the unified gas kinetic scheme.The inflow conditions considered several flow regimes,from the near-continuum through the slip-transitional to the free molecular regime.Flow fields and surface properties were compared in detail between these two methods.Not only the density and temperature contours distribution but also the surface pressure,heat flux,friction distribution,both kinetic methods give fairly consistent results.Aerodynamics of the model were also achieved and compared.The results provided by both methods agreed with each other very well.The effects of the Knudsen number and angle of attack were assessed.It is meaningful to carry out comparative studies and accelerate both methods to further progress. | Jin Li Dingwu Jiang Xiangren Geng Jianqiang Chen | 2021 | Advances in Aerodynamics2021，3，1： | 4 |
| 2 | An implicit parallel UGKS solver for flows covering various regimes显示文摘This paper presents an engineering-oriented UGKS solver package developed in China Aerodynamics Research and Development Center(CARDC).The solver is programmed in Fortran language and uses structured body-fitted mesh,aiming for predicting aerodynamic and aerothermodynamics characteristics in flows covering various regimes on complex three-dimensional configurations.The conservative discrete ordinate method and implicit implementation are incorporated.Meanwhile,a local mesh refinement technique in the velocity space is developed.The parallel strategies include MPI and OpenMP.Test cases include a wedge,a cylinder,a 2D blunt cone,a sphere,and a X38-like vehicle.Good agreements with experimental or DSMC results have been achieved. | Dingwu Jiang Meiliang Mao Jin Li Xiaogang Deng | 2019 | Advances in Aerodynamics2019，1，1： | 1 |
