EnergiesLiquid metal is widely used as the primary coolant in many advanced nuclear energy systems. Prandtl number of liquid metal is much lower than that of the conventional coolant of water or gas. Based on the Reynolds analogy, the turbulent Prandtl number is

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

Flow physics of planar bistable fluidic oscillator with backflow limbs
AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract Fluidic oscillators (FOs) are used in a variety of applications, including process control and process intensification. Despite the simple design and operation of FOs, the fluid dynamics of FOs exhibit rich complexities. The inherently unstable flow, jet oscillations, and resulting vortices influence mixing and other transport processes.

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.

Heat Transfer, Volume 52, Issue 1, Page 395-429, January 2023., 2023 Abstract The significance of hybrid nanofluids in controlling heat transmission cannot be overemphasized. Therefore, this article scrutinizes the electromagnetized flow of Carreau hybrid nanofluid towards a stretching surface in a Darcy–Forchheimer porous medium with the occurrence of slip conditions.

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.

Effects of viscous dissipation and boundary conditions on forced convection in a channel occupied by a saturated porous medium [PDF]
, 2007 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.
