Correlations are proposed for the forced convection and naturalconvection conditions. Both the experimental and the analytical data show that naturalconvection in a loop is characterized by strong nonlinear effects. The interior of the tube was filled with loosely packed pulverized cork, thereby eliminating naturalconvection heat transfer to the interior. Then, under some critical conditions, naturalconvection can appear. Effects of radial electrostatic fields on naturalconvection and forced convection heat transfer to annuli. This is as would be expected as the naturalconvection is aiding the forced convection. The measurements showed no significant wall downflow and no consistent skewing of the temperature profile which might signal the presence of large-scale naturalconvection. However, the experimental evidence of naturalconvection in an internally heated fluid in a porous layer exhibits a peculiar scatter near the onset of convection. Our results show that the effect of dispersion on naturalconvection in this case is fundamentally different from the case without internal heat generation. In reality though, small naturalconvection could be a competitive factor compared to surface effects. A one-dimensional model is derived for naturalconvection in a closed loop. The stability of naturalconvection in a vertical annular enclosure has been studied by the linear theory. The first experiments were a study of the effect of polymer additives on heat-transfer by naturalconvection. The naturalconvection will cause the fluid to move vertically upwards whereas the forcing velocity may be in any direction. The correlation is useful for determining the values at which naturalconvection takes effect on the forcing flow. The onset of laminar-turbulent transition in naturalconvection flow on a vertical plate is characterized by wave-type disturbances (ideally, plane waves travelling in the streamwise direction). Combined forced and naturalconvection. The motion of a fluid in naturalconvection is caused solely by buoyancy forces due to the action of some field of force on the unevenly unheated fluid. The generous open balustrade at roof level eliminates the inevitable overheating by natural convection in summer, but it should ideally be movable to control the unwanted air convection in winter. Displacement ventilation uses the heat from people and solar gain to move air by naturalconvection, the air being introduced at floor level.
