Nusselt number and friction factor in zig-zag microchannels subjected to constant heat flux

International Journal of Thermofluids
This study quantifies the heat transfer coefficient, pressure drop, Nusselt number and friction factor associated with flow of water in zig-zag microchannels, with square cross-section and sharp edges, when subjected to constant heat flux boundary ...

Numerical investigation of hydrodynamic nanofluid convective flow in a porous enclosure

Revue Nature et Technologie, 2023
In this study, the steady state behavior of natural convection transport on a nanofluid in square enclosure was studied. The model equations were solved using Comsol Multiphysics; a solver for partial differential Navier–Stokes equations based on a two ...

Numerical Investigation of Nanofluid Flow over a Backward Facing Step

Aerospace, 2022
Nanofluid flow over a backward facing step was investigated numerically at low Reynolds number and the heat transfer was analyzed and reported. Al2O3–H2O nanofluids of different volume fractions (φ = 1–5%) were used as the material with uniform heat flux

Revisiting Reynolds and Nusselt numbers in turbulent thermal convection [PDF]

Physics of Fluids, 2021
In this paper, we extend Grossmann and Lohse’s (GL) model [S. Grossmann and D. Lohse, “Thermal convection for large Prandtl numbers,” Phys. Rev. Lett. 86, 3316 (2001)] for the predictions of Reynolds number (Re) and Nusselt number (Nu) in turbulent Rayleigh–Bénard convection.

Effects of viscous dissipation and boundary conditions on forced convection in a channel occupied by a saturated porous medium [PDF]

, 2006
Forced convection with viscous dissipation in a parallel plate channel filled by a saturated porous medium is investigated numerically. Three different viscous dissipation models are examined.

An improved method of Nusselt number calculation [PDF]

Geophysical Journal International, 1987
A novel method for calculating the Nusselt number, Nu, in a steady-state Rayleigh-Benard convection problem is presented, in which calculations are done for a square box with constant temperature, free-slip boundary conditions at the top and bottom, and a reflection symmetry along the side walls.
