FORCED CONVECTION CONDENSATION OF AMMONIA INSIDE COILED FLUTED TUBES.

Author(s) : ANAND G., CHRISTENSEN R. N., RICHARDS D. E.

Summary

THE PAPER PRESENTS THE RESULTS OF A SERIES OF EXPERIMENTS ON FORCED CONVECTIVE CONDENSATION INSIDE COILED, DOUBLY-FLUTED TUBES. TWO DIFFERENT DOUBLY-FLUTED TUBES WERE INVESTIGATED IN THE STUDY, AND EXPERIMENTS SHOWED SIGNIFICANTLY DIFFERENT CONDENSATION COEFFICIENTS FOR THE TWO. A MODEL MAKES USE OF FLOW-REGIME-DEPENDENT LOCAL CONDENSATION COEFFICIENTS. THE PREDICTED VALUES WERE COMPARED WITH THE EXPERIMENTALLY MEASURED VALUES, AND THESE COMPARISONS WERE USED TO SUGGEST A MECHANISM FOR CONDENSATION IN THE COILED, DOUBLY-FLUTED TUBES. THE COMPARISONS SUGGEST THAT A DIFFERENT MECHANISMGOVERNS CONDENSATION IN EACH TUBE, AND THIS CAN BE RELATED TO THE SHAPE OF THE FLUTES.
