NUMERICAL PREDICTION OF HEAT TRANSFER TO LOW-PRANDTL-NUMBER FLUIDS

Numerical Heat Transfer, 1979
Numerical prediction of the heat transfer to low-Prandtl-number fluids has been carried out. A one-equation (k) turbulence model in the near-wall region and a two-equation (k ∼ e) turbulence model In the core region are employed. Many expressions proposed in the literature for the Prt numbers are examined.

Novel technique MDDIM solutions of MHD flow and radiative Prandtl-Eyring fluid over a stretching sheet with convective heating

International Journal of Ambient Energy, 2021
Aim of this paper was to appraise the magneto-hydrodynamic boundary layer flow of a Prandtl-Eyring fluid model on the top of stretched sheet. Ancillary to the same, the evolution and process of transfer of heat in the appearance of heat radiation and ...

Thermal attractor in chaotic convection with high-Prandtl-number fluids

Physical Review A, 1988
The onset of chaotic convection in large-Prandtl-number fluids has been found to occur in the form of elongated cells with aperiodic boundary-layer instabilities. The dynamics of this phenomenon has been monitored in the physical domain, and also in the spectral and phase spaces.

Further Results on the Heat Transfer to Low-Prandtl-Number Fluids in Pipes

Numerical Heat Transfer, Part B: Fundamentals, 1982
Abstract Numerical predictions have been made of heat transfer to low-Prandtl-number fluids in pipes with constant wall heat flux. The turbulence model employed is of the two-equation (k-)c kind in the core and the one-equation (k) kind in the near-wall region.

Numerical Simulation of Oscillatory Convection in Low Prandtl Fluids

1990
Our contribution to the GAMM WORKSHOP is limited to the case A: Rigid-Rigid shallow rectangular cavity (of aspect ratio A=4) filled with low-Prandtl-number fluid (Pr=0) and submitted to a horizontal temperature gradient. Additionnal computations were carried out in order to determine the Grashof number value corresponding to the onset of instabilities (
