Gas-kinetic schemes based on the BGK model are proposed as an alternative evolution model which can cure some of the limitations of current Riemann solvers. To analyse the schemes, simple advection eq...

Starting from the gas-kinetic model, a new class of relaxation schemes for the Euler equations are presented. Instead of linerizing the Euler equa-tions into a few simple waves, the new flow solvers a...

St,arting from the BGI< model [I], anew gas-kinetic scheme is developed for computing st,ea.tly st,at,e so-lutions to the Eiiler eqitations. T11c discret.iaat,ioii has been implemented in a well devol...
Gas-kinetic schemes developed from the BGK model have been successfully applied to 1-D and 2-D flows [1,2]. One of the advantages of the gas-kinetic approach over more conventional methods is realized...
