Convective Air Flow from a Heat Source
Calculate the vertical air flow and air velocity generated by a heat source

A heat source, like a big engine, stove or melting pot, will generate a convective vertical air flow.

Air Velocity
The air velocity in the center of the air flow in a distance above the floor can be calculated as
vc = c1 ( 1000 P / l )1/3 (1)
where
vc = air velocity in the center of the air flow (m/s)
c1 = constant characterizing the actual application, typical values between 1 to 2.
P = heating power from the source (W)
l = distance above the floor and the heat source (m)
Air Flow Volume
The air flow in a distance above the the floor can be calculated as
Q = c2 P1/3 l5/3 (2)
where
Q = air flow volume (m3/s)
c2 = constant characterizing the actual application, typical values between 0.05 to 0.15
