Some practical methods of reducing tube side thermal resistance in process heat exchangers are discussed, both for clean surfaces and in the presence of water side fouling. Factors of importance in hard water scaling are outlined. Gains to be made by changes in velocity, tube geometry and surface area augmentation are explored.
