Abstract The flow of an active thermal protection system exploiting subsonic counter-flow jets for wing leading edges of hypersonic vehicles is numerically studied on the basis of the three dimensional Navier-Stokes equations. The coolant air issuing

Developed is a high-order accurate shock-capturing scheme for the compressible Euler/Navier–Stokes equations; the formal accuracy is 5th order in space and 4th order in time. The performance and efficiency of the scheme are validated in various num

The Artificial Compressibility Method (ACM) for the incompressible Navier-Stokes equations is (link-wise) reformulated (referred to as LW-ACM) by a finite set of discrete directions (links) on a regular Cartesian mesh, in analogy with the Lattice Bol

The artificial compressibility method for the incompressible Navier-Stokes equations is revived as a high order accurate numerical method (fourth order in space and second order in time). Similar to the lattice Boltzmann method, the mesh spacing is l

The high-resolution scheme for the compressible Navier-Stokes equations developed in Ohwada and Kobayashi [Management of discontinuous reconstruction in kinetic schemes, J. Comput. Phys. 197 (2004) 116-138] is rederived without using any special tech

The present paper highlights the importance of management of the discontinuous reconstruction in the kinetic schemes for gasdynamic equation systems. Firstly, it is revealed by the analysis of the gas kinetic-BGK scheme [JCP 171 (2001) 289] that a co

The present paper concerns two aspects for the Burnett equations. First, we are going to theoretically show the consistency between the traditional Chapman-Enskog expansion and the successive approximation for the BGK equation up to the super-Burnett

A general method for the construction of kinetic schemes of evolutionary equations is illustrated with the simple example of the linear advection equation, where the role of the collision effect is clarified theoretically and numerically. The applica
