heat convection

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.

CWB forecaster Chen Chien-an said that heat convection in the afternoon would cause thunderstorms to spread across Taiwan.
This is made possible by its 62-degree golden angle giving the ideal circular heat convection for homogenous and delicious cooking.
Porous media has two specifications: First its dissipation area is greater than the conventional fins that enhance heat convection. Second the irregular motion of the fluid flow around the individual beads mixes the fluid more effectively.
In the range of [T.sub.ONB] [less than or equal to] [T.sub.w] [less than or equal to] [T.sub.CHF], Rohsenow correlation [9] is used for the heat convection coefficient:
(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.
The Life-Bed is waterproofed 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.
The convective coefficient is applied equal to 8.1 W/[m.sup.2*]K, however, heat convection of magnetic devices can vary in the range 6-10 W/[m.sup.2*]K [9].
When a low but effective heat convection is realized in proximity of the sample boundary (as in the validated case, when the heat transfer coefficient U is 5W [m.sup.-2] [K.sup.-1]), a temperature gradient develops in a sample layer in proximity of the boundaries (Figure 4(b)).
