Mixed convection in a square enclosure with a rotating flat plate

Mixed convective heat transfer enhancement in a ventilated cavity by flow modulation via rotating plate

“…Comparison of the variation of Nu with time between Lee et al 33 and present model, at Re = 430 and d = 0.6 [Color figure can be viewed at wileyonlinelibrary.com]…”

“…Moreover, the present numerical procedure of moving mesh has been compared with the existing results of Lee et al 33 The variation of Nusselt number with dimensionless time for d = 0.6, and Re = 430 for four representative Rayleigh numbers ( Ra ) have been compared, as presented in Figure 4. The consistency of the present simulation outputs with the prior studies provides enough confidence to ensure the precision of the current simulation process.…”

Mixed convection heat transfer from a vertical flat plate subjected to periodic oscillations

“…They changed the oscillation amplitude, oscillation frequency and orientation angle, and the maximum heat transfer coefficient was obtained at the horizontal position and at high frequencies. Lee et al [32] numerically examined mixed convection heat transfer of a flat plate rotating in a square enclosure. The studies were performed for different Rayleigh number and rotational Reynolds number with constant Prandtl number (Pr = 0.71).…”

Nonlinear approximation for natural convection and mass transfer in a vertical channel

“…Nanoparticles are tiny particles ranging from 1 to 100 m. They can be classified base on their shape, sizes, and properties and they are usually made from metals such as gold and copper oxide like titania, silica, copper oxide, and alumina. Nanoparticles have been used for drug delivery according to Lee et al, 2 biological and chemical sensing Taghite et al, 3 gas sensing, 4-6 CO 2 capturing Ganesh et al 7 and Ramacharyulu et al 8 Other practical applications of nanoparticles can be found in Shaalan et al 9 Nanofluid is applied in various fields of endeavor ranging from the biomedical arena such as nano drug delivery, cancer therapeutics, cryopreservation, sensing and imaging and nanosurgery [10][11][12][13][14] to the automotive industries such as nanofluids in fuel, nanofluid coolant, brake and other vehicular nanofluids [15][16][17] to electronics such as cooling of microchips and microscale fluidic 18 and 19 to power plants such as nuclear reactor, smart fluid, and extraction of geothermal power and other energy sources. [20][21][22] Jawad et al 23 analyzed unsteady bioconvection Darcy-Forchheimer nanofluid flow through a horizontal channel with thermal radiation and magnetic field.…”
