An asynchronous scheme with local time stepping for multi-scale transport problems: Application to gas discharges

International audienceThis paper presents an asynchronous integration scheme with local time stepping for transport problems. The conceptconsists in associating refresh time tags to the interface fluxes between cells and to the source terms within the cells ratherthan to the cell themselves. This scheme is less diffusive numerically than its synchronous equivalent. This method is veryeffective in terms of computation time for problems with localized sharp minima in the CFL condition. The method is thenapplied to dielectric barrier discharges for aerodynamic flow control.Ó 2007 Elsevier Inc. All rights reserve
