heat convection

[′hēt kən¦vek·shən]
(thermodynamics)
The transfer of thermal energy by actual physical movement from one location to another of a substance in which thermal energy is stored. Also known as thermal convection.

In the final effect of horizontal plates, two symmetrical boundary layers exist, growing from each edge (region I = region II) and transforming at the separation point into free stream heat convection (plume).
2) Only heat conduction inside the oil shale particle is considered, while heat convection, radiation and mass transfer inside the pores are ignored [19, 25, 26].
Under condition B3, the boundary condition of strong heat convection between the high-temperature compressed gas and compression chamber placed the cover side in opposition to the frictional heat transfer, thereby aggravating the pressure ratio, which increased with an increase in discharge temperature.
The G20 has a thermal design that takes advantage of natural heat convection, and has a hidden airflow channel to ensure efficient heat management during marathon gaming sessions.
The Life-Bed is waterproof and has four air insulating layers to avoid heat convection with the ground and prevent hypothermia.

This type of resistive force tends to slow down the flow which, in turn, reduces the rate of heat convection in the flow and this appears in ncreasing the flow temperatures as in Fig.
As for the gas, the heat convection is the main way and the order of magnitude for the heat convection is much greater than the one for the heat conduction and the thermal radiation.
Plans for an atmospheric vortex engine propose a process for capturing the mechanical energy produced during upward heat convection.
The waterside heat convection coefficient was estimated using Dittus-Boilter equation from laminar to turbulent flow.
By building what we call an atmospheric vortex engine, one could capture the mechanical energy produced during upward heat convection when warm or humid air is admitted tangentially at the base of a cylindrical enclosure.
