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 ...

Altitude Effects on Ejected Flames in Façade Calibration Tests: Experimental and Numerical Investigation

open access: yesFire and Materials, EarlyView.
ABSTRACT Ejected flames from a compartment opening pose a significant fire hazard to building fire safety, serving as a trigger of rapid façade flame spread. Although extensively studied under standard altitude conditions, their fire behavior under subatmospheric pressure remains to be further explored.

Entropy Generation and Heat Transfer in a Circular Cavity With Immiscible Fluids: Effects of Active Cylinder Position and Oscillating Magnetic Field

open access: yesHeat Transfer, EarlyView.
ABSTRACT This study investigates entropy generation and heat transfer in a circular cavity containing immiscible air and TiO2–water nanofluid layers with a centrally positioned active cylinder under oscillating magnetic field influence. The governing equations were solved using the Galerkin weighted residual finite element method with a penalty ...
