this paper presents the results of a numerical study on the heat transfer performance and the removal process of fluid particles under the influence of magnetohydrodynamic mixed convection in a horizontal channel with an open cavity. the bottom wall of the cavity is heated at a constant temperature (th) while the top wall of the channel is maintained at a relatively low temperature (tc). air wi...

in the present research mixed convection flow through a copper-water nanofluid in a driven cavity in the presence of magnetic field is investigated numerically. the cavity is heated from top and cooled from bottom while its two vertical walls are insulated. the governing equations including continuity, n-s and energy equations are solved over a staggered grid system. the study is conducted for ...

double-diffusive mixed convection in a lid-driven square enclosure filled with al2o3-water is numerically investigated. two-dimensional nonlinear governing equations are discretized using the control volume method and hybrid scheme. the equations are solved using simpler algorithm. the results are displayed in the form of streamlines, isotherms, and iso-concentrations when the richardson number...

The paper is devoted to the study of formation stratification in an incompressible fluid due convective laminar flows horizontal layers heated from side. Medium and intensive modes stationary thermal, concentrational thermo-concentrational (in particular thermohaline) convection are considered, which nonlinear flow features manifested, can radically change structure characteristics heat mass tr...

Numerical predictions of heat transfer have been made for laminar free and mixed convective from non-isothermal vertical plane surface to supercritical water. Variation all the thermo-physical properties fluid under investigation considered. The numerical scheme employed in present is first validated with respect experimental data isothermal wall conditions good agreement achieved maximum devia...

It is shown that laminar thermal convection can drive a chain reaction of DNA replication. The convection is triggered by a constant horizontal temperature gradient, moving molecules along stationary paths between hot and cold regions. This implements the temperature cycling for the classical polymerase chain reaction (PCR). The amplification is shown to be exponential and reaches 100,000-fold ...
