Abstract
A new kinetic scheme for the compressible Navier-Stokes equations is introduced. While the conventional approach, such as KFVS scheme, employs the splitting algorithm and computes the numerical flux on the basis of the collisionless equation, the present approach takes account of the collision effect. This scheme is constructed as a fortified Lax-Wendroff with an armament of a kinetic smooth reconstruction created by a discontinuous one and is robust and accurate; it yields satisfactory results in both shock and boundary-layer flows.
