Definition of turbulent flow. : a fluid flow in which the velocity at a given point varies erratically in magnitude and direction â compare laminar flow.
Heat Convection. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law).eat Convection.
