A universal relation for calculating convective heat transfer in transversely streamlined bundles of smooth tubes

Abstract

Experimental data on convective heat transfer in smooth-tube bundles streamlined by a transverse flow in the range of Reynolds numbers from 3 × 103 to 1 × 105 are generalized. A universal relation is obtained that allows heat transfer in bundles with staggered and in-line arrangements to be calculated in the range of pitch characteristics covering all practical applications with better accuracy as compared with the well-known calculation procedures.
