Similar to forced convection, heat transfer due to free convection is described by Newton's Law of Cooling, |
The rate of heat transfered to the surrounding fluid is proportional to the object's exposed area A, and the difference between the object temperature T_{w} and the fluid free-stream temperature .
The constant of proportionality h is termed the convection heat-transfer coefficient. Other terms describing h include film coefficient and film conductance. Variables needed to parameterize free convection are: |
