This paper presents a review of the accuracy of the Simplified Bernoulli Trial (SBT) algorithm and its invariants, i.e., SBT-TAS (transient adaptive subcells) and ISBT (intelligence SBT) in the simulation of a wide spectrum of rarefied flow problems, ranging from collision frequency ratio evaluation in the equilibrium condition, comparison of the Sonine-polynomial coefficients prediction in the Couette flow with the theoretical prediction of the Chapman-Enskog expansion, accurate wall heat flux solution for the Fourier flow in the slip regime, rarefied flow over NACA0012 airfoil, flow inside micro/nano nozzles and divergent channels, and hypersonic flows over cylinder and biconic geometries [1-6]. We summarize advantages and requirements that utilization of the SBT collision algorithm brings to a typical DSMC solver.
