Natural convection in a square Cavity: Effects of Rayleigh and Prandtl numbers on heat transfer and flow patterns

open access: yesCase Studies in Thermal Engineering
Natural convection within enclosures plays a crucial role in heat transfer across various thermal systems. This study presents a validated numerical benchmark for buoyancy-driven flow in a square cavity with differential heating, focusing solely on the ...

Hot-wire experimental investigation on turbulent Prandtl number in a rotating non-isothermal turbulent boundary layer

open access: yesPropulsion and Power Research, 2020
This experiment used a parallel array of hot wire probes to simultaneously measure the temperature and velocity fields in the non-isothermal turbulent boundary layer of a rotating straight channel. The Reynolds numbers are 15,000 and 25,000, respectively.

Finite Difference Analysis of Prandtl Number and Particle Volume Fraction Effects on Skin Friction and Heat Transfer in Buoyancy Driven Two-Phase Flow with Suspended Particulate Matter (SPM)

open access: yesEast European Journal of Physics
A numerical investigation has been conducted on incompressible, laminar two-phase buoyancy driven flow containing suspended particles around a vertical plate. Despite the relevance of such systems, prior studies have largely overlooked natural convection

Investigation of Turbulence and Turbulent Prandtl Number Models for He-Xe Thermal Hydraulics in Quasi-Triangular Channel

open access: yesEnergies
Compact nuclear reactor systems usually use helium–xenon (He-Xe) mixtures as coolants. Tight-lattice rod-bundled channels, serving as primary core configurations in compact nuclear reactor designs, exhibit quasi-triangular cross-sections where fluid ...
