Direct numerical simulations of spatially developing mixing layer were conducted by a higher-order accurate hybrid scheme with newly developed inflow and outflow boundary conditions. The boundary conditions consists of convection-viscous conditions for the velocity field and an approximate transport equation for the pressure. The applicability of these boundary conditions was verified by comparing the solutions of two simulations with two different computational domains. The vorticity, pressure and velocity fields with the shorter domain exactly agree with those with the longer domain. Correlation coefficients for higher-order statistical properties are also very high because the influence of the boundary conditions is very slight. From these results, we can conclude that the proposed boundary conditions are appropriate for direct numerical simulations of spatially developing mixing layers.
