MHD free convection flow in an inclined square cavity filled with both nanofluids and gyrotactic microorganisms

International journal of numerical methods for heat & fluid flow, 2019
Purpose This paper aims to study the magnetohydrodynamic (MHD)-free convection flow in an inclined square cavity filled with both nanofluids and gyrotactic microorganism.

The free-convective anomaly

Journal of Applied Physiology, 1999
Persons exposed to high temperature, or to equivalent environmental factors, have quantifiable reactions, such as reducing the resistance to both heat and moisture flow in skin tissues and clothing needed to maintain thermal equilibrium. The one-to-one relationship between this resistance in the walking person and temperature, with the other factors ...

Convection-free boundary sedimentation

Analytical Biochemistry, 1972
Abstract A simple technique is described that prevents the occurrence of convective flows in boundary sedimentation experiments. Superimposed density gradients employed as in band centrifugation are evaluated quantitatively. The usefulness of the method is demonstrated by comparison of stabilized and nonstabilized experiments run under identical ...

Unsteady Laminar Free Convection

Journal of Heat Transfer, 1961
The unsteady, laminar, free-convection boundary layer is analyzed with the Grashof number considered to be time-dependent through either the uniform wall temperature or the acceleration field. Two geometries are considered; the vertical plate and the horizontal circular cylinder.

Horizontal free convection

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1990
The boundary-layer flow over a heated horizontal plane boundary is analysed. Temperature variations along the boundary induce a pressure gradient that drives the flow. From consideration of an exact solution it is shown that no steady boundary-layer solution exists at a point where the temperature is a maximum.

Magnetohydrodynamic Unsteady Free Convection

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1967
AbstractThe unsteady free convection flow from an infinite vertical plate, under the action of a transverse magnetic field, is analysed in the case when the plate temperature undergoes a thermal transient. The solution is obtained by Laplace transform technique. The applied field is found to induce a wave‐dominated flow pattern.

Turbulent free convection flow

International Journal of Heat and Mass Transfer, 1974
Abstract The results of an experimental investigation of a turbulent free convection boundary layer are presented for a fluid with a low Prandtl number (mercury). The boundary layer was formed along the isothermally heated vertical wall of a cell. The measured mean temperature profiles and turbulent temperature distributions, indicated the existence

Micropolar free convection flow

International Journal of Heat and Mass Transfer, 1973
Abstract The flow and heat-transfer characteristics of the free convection micropolar flow are described. It is found that decreasing rates of heat-transfer can be achieved by making the Newtonian solvent more and more micropolar. The micropolar characteristics are determined by the two non-dimensional parameters R (an index to microstructure ...

Ice‐Free Radiative Convection Drives Spring Mixing in a Large Lake

Geophysical Research Letters, 2019
In this work we highlight the importance of radiative convection as a mixing mechanism in a large, ice‐free lake (Lake Michigan, USA), where solar heating of waters below the temperature of maximum density drives vertical convection during the vernal ...
