free convectionhydrodynamicsturbulenceThe evolution properties of free convective motion of air in a heated space have been investigated by numerical modeling. The air motion is always nonstationary and turbulent. The existing technical constraint on the grid scale makes it possible to observe only ...
convection Air heated by a space heater rises and is replaced by cool air, creating a convection current that circulates hot air throughout a room. con·vec·tion (kən-vĕk′shən) n. 1.The act or process of conveying; transmission. ...
hi all, here is a simple textbook problem: "free convection(of air) on a vertical flat plate"... my approach: plate is at a uniform temperature 0f 100 deg c. i have taken a rectangular domain surrounding one side of the plate. one boundary condition is clear i.e plate at uniform ...
The heat transfer by free convection from a heated 60° vee-corrugated plate to a cooled flat plate placed above it has been studied, with the cold flat plate and the vees horizontal. Correlations of Nusselt and Grashof numbers have been obtained, and discussed in relation to the correlation...
1.A community, especially of nuns, bound by vows to a religious life under a superior. 2.The building or buildings occupied by such a community. [Middle Englishcovent, from Old French, from Medieval Latinconventus, from Latin,assembly, from past participle ofconvenīre,to assemble; seeconvene...
Research of horizontal single-row bundles of ribbon finned tubes at free convection The methods of theoretical analysis for heat transfer of bodies of complex shape are too voluminous and cumbersome. The intensification of free-convective heat transfer is possible through the use of various types of...
7. It consists of a cavity whose glass dome (6a, 7a, 7c) is covered with a thin layer of an aluminized paint electrically Conclusions This work provides Nusselt–Rayleigh type correlations that allow calculating the heat exchanges that occur by natural convection in air-filled hemispherical ...

Since sea water is about 1000 times denser than air, the air–sea interface from the water side can be considered a free surface. So-called thermocapillary convection can develop near this surface owing to the dependence of the surface tension coefficient on temperature. There are experimental ind...
