A steady laminar natural convection of air flow in a sinusoidal corrugated enclosure containing a tilted hot thin plate located symmetrically at its centreline is numerically studied. The enclosure horizontal walls are adiabatic, while the vertical walls are sinusoidal corrugated with corrugation ...
The attached Heat sink gets a Heat Flux of 50 W on its lower surface. The natural convection of the air arround the Heat sink cools it. Seems to be a simple case. I want to solve it with the chtMultiRegionSimpleFoam solver because all i need is the steady state (right solver?). ...
Natural convection cooling using air as a fluid is commonly used in the cooling of electronic equipment and many other devices. In this work, a three-dimensional numerical study of natural convection heat transfer from multiple protruding heat sources simulating electronic components is conducted. ...
They prove that building designer needs to know the airflow patterns, temperature distributions and heat flows at solar protection devices close to window. The majority of the work accomplished in this area has been interested to natural convection in enclosures due to either vertically or ...
Fluid flow and heat transfer of natural convection around large horizontal cylinders were investigated experimentally. The main concerns were the turbulent transition and its influence on the local heat transfer. The experiments were performed in the range of modified Rayleigh numbers from 1.0×10<SUP>...
A 3-D numerical study has been performed to investigate the influence of aperture characteristics, i.e., aperture position and size on natural convection heat loss of this heat-pipe receiver accounting for air property variation with temperature. Temperature and velocity contours as well as the ...
Convection heat transfer was experimentally investigated for two different geometries. One case had three horizontal cylinders in a vertical plane placed between two vertical walls. The second case had three horizontal cylinders in a vertical plane with only one vertical wall. Several different cylinder...
An experimental study has been conducted to determine the influence of eccentricity and Rayleigh number on natural convection heat transfer through a fluid bounded by two horizontal isothermal cylinders. Eccentricity of the inner cylinder substantially alters the local heat transfer on both cylinders, but...

Re: Natural convection with heat flux #5 Anton Guest Posts: n/a Hi! Thank you for your reply! Rayliegh number is about 3.6e8. I think, i defined all properties correct.. Density as boussinesq, thermal expansion coefficient 5.9e-3. Can i define a negative heat flux at all? maybe...
