On the interaction between the shock wave attached to a wedge and freestream disturbances. THEORETICAL AND COMPUTATIONAL FLUID DYNAMICS, 7, The DGM formulation for the LNS equations is described in Section 3, as well as the time integration algorithm, based on a low dissipation formulation of a fourth-order accurate Runge–Kutta scheme. Explicit time integration, more appropriate for acoustic wave propagation, avoids the inversion of a large algebraic system, and it is well Cited by: 2.

    schemes: the DRP scheme and the OPC scheme. A low dispersion and low dissipation Runge-Kutta proposed by Hu and coworkers () is employed for the time stepping procedure, and combined with the DRP and OPC schemes. A study of the dispersive characteristics and stability is presented for these schemes. The boundary treatment is presented in. High-order finite difference schemes can be classified into two main categories: explicit schemes and Pade-type or compact schemes. Explicit schemes compute the numerical derivatives directly at each grid by using large stencils, while compact schemes obtain all the numerical derivatives along a grid line using smaller stencils and solving a.
