The process of heat transfer from one particle of the fluid to another by the actual movement of the fluid particles caused by some mechanical means, is known as Forced convection
Forced convection is a special type of heat transfer in which fluids are forced to move, in order to increase the heat transfer.
This forcing can be done with a ceiling fan, a pump, suction device,
