Low-Cost Energy-Preserving RK Schemes for Turbulent Simulations

摘要: A low-cost numerical strategy is presented for energy-preserving simulations of incompressible flows. This method consists in an explicit Runge–Kutta scheme which the divergence and advective forms convective term are suitably alternated within sub-steps. As a result, conservation properties skew-symmetric form recovered at reduced computational cost. The performances accuracy proved by simulations.
