Convective Heat Transfer and Fluid Dynamics in Heat Exchanger Applications

Part of the Heat and Mass Transfer book series (HMT)

Abstract

This article concerns the local structure of flow and temperature fields as well as overall heat transfer coefficients and pressure drops in flow passages of relevance for heat exchangers. Results from investigations using flow visualization, laser doppler-velocimetry and IR-thermography together with more conventional overall measurements are presented. The usefulness and opportunities with the modern techniques are discussed.
