Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle.
32.
Typically, the natural convection is negligible when Ri 10, and neither is negligible when 0.1 < Ri < 10.
33.
After heating has stopped, mixing and conduction from this natural convection eventually result in a nearly homogeneous density, and even temperature.
34.
The first application of heatlines was in the visualization of laminar natural convection in a two dimensional rectangular enclosure heated from the side.
35.
The transition to turbulent flow occurs in the range " 10 8 L 9 " for natural convection from vertical flat plates.
36.
The fighting compartment was, albeit poorly, ventilated by natural convection, exiting out the rear of the superstructure through two armored covers.
37.
:It would depend a lot on whether the internal and or external air is stirred by a fan or left to natural convection.
38.
It may be noted that usually the forced convection is large relative to natural convection except in the case of extremely low forced flow velocities.
39.
To improve cooling of large power transformers, the oil-filled tank may have external radiators through which the oil circulates by natural convection.
40.
Therefore, Grashof number can be thought of as Reynolds number with the velocity of natural convection replacing the velocity in Reynolds number's formula.
