Readily available data on turbulent transfer in plate heat exchangers can be correlated by a heat transfer-energy dissipation analogy: N~ 3 e g,~Pr,Vi) = C 3(fRe ) in which the Nusselt number modified for changes in the Prandtl number and bulk to wall viscosity ratio Vi is related to the friction fa
The sea-water samples used had a chlorinity of 16 and were obtained from the Firth of Clyde near the entrance to Loch Long. Their surface tension at IOWC was found to be 58.7 dyn/cm, as compared with 71.8 dyn/cm for a sample of freshwater. The freshwater used for comparison was Glasgow City water.
Heat transfer and pressure drop characteristics are investigated here using experimental and analytical techniques for a dimple plate heat exchanger. The analysis uses the log mean temperature difference method (LMTD) in all its calculations. Whilest the shell side flow highly resembles the flow ove
