A METHOD FOR DETERMINING OIL-COOLER PERFORMANCE REQUIREMENTS IN SERIES OPERATION

摘要

An equation has been developed by which the over-all performance of any number of oil coolers when operating in series can be related to their performance when operating singly. This relation is of value to the designer of power-plant installations in determining the individual performance required of identical coolers connected in series to obtain a desired over-all performance. The method is strictly applicable only when there is no oil diversion and when the heat-transfer coefficients on the oil side of the individual coolers do not vary with inlet oil temperature with the coolers in series.
