Combined Effect of Radiation and Natural Convection in a Square Cavity Differentially Heated with a Periodic Temperature

Heat transfer enhancement of mixed convection in a square cavity with inlet and outlet ports due to oscillation of incoming flow

“…They observed that the best heat transfer rate is comprehended when the dimensionless frequency (Strouhal number) is close to unity and also heat transfer is enhanced in comparison to the steady state case. The effects of the oscillation on the heat transfer and fluid flow have been investigated by the other researchers [13][14][15][16][17][18]. Khanafer et al [19] investigated numerically, unsteady laminar mixed convection heat transfer in an oscillating lid-driven cavity to study the effects of Reynolds number, Grashof number and oscillating frequency on heat transfer.…”

Effects of adiabatic extensions on heat transfer through a differentially heated square cavity

“…The active approaches utilise external energy to change the state of the natural convection flow and in turn enhance heat transfer. Examples of active approaches include enhancement using sound waves [10], oscillating wall temperatures [2,11,12], ultrasonic vibration [3], etc. In contrast to the active approaches, the passive approaches do not require external energy supply.…”

Numerical Simulation of Low-Mach-Number Laminar Mixing and Reacting Flows Using a Dual-Purpose Pressure-Based Algorithm

“…They used the augmented gradient method incorporating a second-order finite-volume method in space, an implicit Euler scheme in time, and a coupled velocity-pressure equation to perform their study. A few other researches can be counted, such as those to control the heat transfer rate in buoyant domains with large radiative effects [10][11][12][13][14] and to investigate concentration and double-diffusive convection [15][16][17].…”
