MATHEMATlCAL AND PRACTICAL ASPECTS OF HEAT TRANSFER IN DOUBLE PIPE HEAT EXCHANGERS
要約
A mathematical analysis of heat transfer in double-pipe heat exchangers, based on first principles
rather than on the use of heat transfer coefficients, is generalized to include laminar or turbulent flows,
various geometrical configurations, and both co-current and counter-current operation. Practical aspects
concentrate on accurate predictions of overall heat transfer rates, and include consideration of a quantity
called the "Effectiveness Coefficient" for this purpose. Procedures for the interpretation of experimental
data, derived from the analysis, are also suggested.
