Abstract

•A two-dimensional implementation of the ellipsoidal statistical Fokker–Planck (ES-FP) model is presented.•Analytical solution for the initial-value problem of the spatial homogeneous ES-FP equation is obtained.•Supersonic flat-plate flows at different Knudsen numbers ranging from 0.001 to 0.1 are simulated with the ES-FP solver.•The ES-FP simulation shows better numerical efficiency than DSMC at low Knudsen numbers.•Numerical simulations verify the correct Prandtl number underlying the ES-FP model.
