DNS of thermal channel flow up to Re-tau=2000 for medium to low Prandtl numbers

Alcántara-Ávila, Francisco; Hoyas, S.; Pérez Quiles, María Jezabel (Elsevier, 2018)

[EN] Direct Numerical Simulations of turbulent heat transfer in a channel flow are presented for three different Reynolds numbers, namely Re-tau = 500, 1000 and 2000. Medium and low values of the molecular Prandtl number ...
Influence of the computational domain on DNS of turbulent heat transfer up to Re-tau=2000 for Pr=0.71

Lluesma-Rodriguez, F.; Hoyas, S.; Pérez Quiles, María Jezabel (Elsevier, 2018)

[EN] We present a new set of direct numerical simulation data of a passive thermal flow in a turbulent plane Poiseuille flow with constant Prandtl number Pr = 0.71, and mixed boundary conditions. Simulations were performed ...
Validation of symmetry-induced high moment velocity and temperature scaling laws in a turbulent channel flow

Alcántara-Ávila, Francisco; García-Raffi, L. M.; Hoyas, S; Oberlack, Martin (American Physical Society, 2024-02-14)

[EN] The symmetry -based turbulence theory has been used to derive new scaling laws for the streamwise velocity and temperature moments of arbitrary order. For this, it has been applied to an incompressible turbulent channel ...
