This paper presents a class of high resolution KFVS (kinetic flux vector splitting) finite volume methodsfor solving three-dimensional compressibleEuler equations with γ-gas law.The schemes are obtained based on the important connectionbetween the Boltzmann equation and the Euler equations.According to the sign of the normal molecular velocitycomponent at the surface of any control volumes,one gives a splitting of the macroscopic flux vector, I.e.writes the macroscopic flux vector into the sum form ofa positive flux and a negative flux.The initial reconstruction is applied to improveresolution of the schemes. Several numerical resultsare also presented to show the performance of our schemes.
