Table 2 Bulk values of root-mean-square Favre-averaged fluctuations of velocity components \(u''_{rms_b}\), \(v''_{rms_b}\), \(w''_{rms_b}\) and temperature \(T''_{rms_b}\), and wall-averaged Nusselt numbers at the hot/top wall \(Nu_{hw}\), the cold/opposite wall \(Nu_{cwo}\), and cold/lateral wall \(Nu_{cwl}\) of the DNS cases.
