A robust method for time-accurate calculation of variable density, low-Mach number flows is proposed. The collocated grid arrangement is used, which is easier to implement in complex geometries. The flux interpolation technique is used to avoid the odd–even decoupling of the pressure field. Figure 14 shows the computational mesh used for DNS of non-isothermal turbulent channel flow.
