Velocity Field and Pressure Drop in Single-Phase Flows

Abstract

The available experimental data on the flow of incompressible fluids are generalized. These data encompass a wide range of Reynolds numbers that correspond to laminar, transient and turbulent regimes of the flow. Thermal effects due to energy dissipation are estimated. Laminar drag reduction in micro-channels using hydrophobic surfaces is discussed. Data of experimental investigations related to the flow in smooth and rough micro-channels are compared with predictions of the conventional theory. Possible sources of divergence of experimental and theoretical results are also discussed. L.P. Yarin, Fluid Flow, Heat Transfer and Boiling in Micro-Channels
