In this study, the kinetic inviscid flux (KIF) is improved and an implicitstrategy is coupled. The recently proposed KIF is a kind of inviscid flux,whose microscopic mechanism makes it good at solving shock waves, withadvantages against the shock instability phenomenon. When developing theimplicit KIF, a phenomenon is noticed that the kinetic flux vector splitting(KFVS) part in boundary layers not only reduces the accuracy, but seriouslyreduces the Courant-Friedrichs-Lewy (CFL) number as well. As a result, in thispaper, a new weight is proposed about how to combine the KFVS method well withthe totally thermalized transport (TTT) method. Besides admitting the using oflarger CFL numbers, this new weight brings about more accurate numericalresults like pressure, friction coefficient and heat flux when solving shockwaves, boundary layers and complex supersonic/hypersonic flows. In order toexamine the validity, accuracy and efficiency of the present method, sixnumerical test cases, covering the whole speed regime, are conducted, includingthe hypersonic viscous flow past a cylinder, the hypersonic double-cone flow,the hypersonic double-ellipsoid flow, the laminar shock boundary layerinteraction, the supersonic flow around a ramp segment and the lid-drivencavity flow. The advantages of this scheme and corresponding mechanisms are tobe discussed in detail.
