An experimental study on the pressure drop and heat transfer through straight and curved small diameter tubes
TL;DR: In this article, an analytic model to determine the pressure loss through curved tubes, referred to as the modified friction factor, is proposed, thus confirming the suitability of this model for determining pressure losses for different shape of tubes for different heat exchanger types.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.
