PERIODICALLY CONVERGING-DIVERGING TUBES AND THEIR TURBULENT HEAT TRANSFER, PRESSURE DROP, FLUID FLOW, AND ENHANCEMENT CHARACTERISTICS.

Author(s) : SOUZA MENDES P., SPARROW E. M.

Type of article: Article

Summary

THE INVESTIGATED TUBES CONSISTED OF A SUCCESSION OF ALTERNATELY CONVERGING AND DIVERGING CONICAL SECTIONS (IE, MODULES) PLACED END TO END. SYSTEMATIC VARIATIONS WERE MADE IN THE REYNOLDS NUMBER, THE TAPER ANGLE OF THE CONVERGING AND DIVERGING MODULES, AND THE MODULE ASPECT RATIO. FOR EQUAL MASS FLOW RATE AND EQUAL TRANSFER SURFACE AREA, THERE ARE LARGE ENHANCEMENTS OF THE HEAT TRANSFER COEFFICIENTS FOR PERIODIC TUBES, WITH ACCOMPANYING LARGE PRESSURE DROPS.
