“…This behavior is similar to constant property cases with the same Pr w , but different Re τ values (see, e.g., Ref. [2]). Similarly, cases LL and VλSPr LL , which exhibit quasisimilar Pr profiles, also show quasisimilar conductive heat flux profiles, despite the different Re τ profiles.…”

“…A Prandtl-number-dependent shift also occurs when comparing profiles of θ/θ τ for constant property cases at different Prandtl numbers, as can be seen by comparing case CP395 Pr1 with CP395 Pr4 (also see, e.g., Ref. [2]). Similar to u vD , which does not collapse for cases with Re τ gradients, θ vD also deviates significantly for cases with Re τ gradients.…”

“…It can be seen from the DNS predictions that as the Prandtl number increases, the near-wall peak moves closer to the wall and the RMS increases indicating an increase in the scalar fluctuations. The RMS profiles also show a linear scaling with y + in the near-wall region, see also Kawamura et al (1998). The RMS profile has two peaks.…”

“…While a much broader research effort has been devoted to the modeling of turbulent flow [4,5], the effort to simulate and develop models for turbulent heat transfer has been more limited [10][11][12][13][14][15][16][17]. The simulations are mainly divided into two categories: those that are based on the Eulerian approach to describing transport phenomena (and where the system of reference is not moving), and those that…”
