To think, you must stop. You physically must stop talking! So when we are in talk mode, especially fast talk mode, we are in a zone that puts our thinking selves aside. 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.
Principal differences between heat transfer in laminar flow and that in turbulent flow In discussing heat transfer to or from a fluid flowing through a straight circular tube, it is useful to distinguish between the axial or main flow direction, and the directions that lie in a plane perpendicular to the tube axis.emember that the purpose of using a heat transfer coefficient is to calculate the heat flux between the wall and the fluid. In the case of uniform wall flux, we can use an energy balance directly to infer the way in which the bulk average temperature of the fluid changes with distance along the axial direction.
