An experimental study of the unsteady thermal flow around a thin fin on a sidewall of a differentially heated cavity

“…Consequently, the presence of fin significantly changes the early transient thermal boundary layer flow following sudden heating. In the quasi-steady stage, a double-layer structure adjacent to the finned sidewall is formed and no clear separation of the flow around the fin is observed, which is consistent with the observations in Shakerin et al (1988).…”

Electrohydrodynamic enhancement of heat transfer in vertical fin array using computational fluid dynamics technique

“…For large Rayleigh number, heat transfer is dominated by convection instead of conduction. Modification of heat transfer in the finned enclosures is briefly reviewed [1][2][3][4][5][6][7][8][9].…”

“…Laminar natural convection in an enclosure with roughness elements was numerically and experimentally conducted by Shakerin et al [1]. Natural convection in an air-filled differentially heated inclined square enclosure with a thermal thin partition placed at the middle of its cold wall was numerically studied by Frederick [2].…”

Control of Flow and Heat Transfer in a Porous Enclosure due to an Adiabatic Thin fin on the Hot Wall

“…Khashan (2006) have used this model for numerical simulation of thermal non-equilibrium natural convection in a porous cavity, heated from below. The study of natural convection heat transfer, in an enclosure filled with fluid due to attaching partitions and fins at the wall, has been carried out by several authors in the recent years (Shakerin et al 1988;Frederick 1989a;Frederick and Valenica 1989b;Nag et al 1993;Shi and Khodadahi 2003;Bilgen 2005). Shakerin et al (1988) have demonstrated natural convection in a differentially heated rectangular enclosure with discrete roughness elements on a vertical heated wall numerically and verified experimentally.…”
