To awaken the thinking brain, we must stop talking. Great thinkers know this, and will use lines like, Let me think about that for a second..
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.
Fig. 1: Forced convection. It is assumed that the velocity of the fluid is zero at the wall, this assumption is called no â slip condition. As a result, the heat transfer from the solid surface to the fluid layer adjacent to the surface is by pure conduction, since the fluid is motionless.
