Type of article: Article

Summary

AN ANALYTICALLY BASED COMPUTER PROGRAM WAS USED TO CALCULATE THE PERFORMANCE BENEFITS PROVIDED BY THE USE OF ENHANCED TUBE GEOMETRIES IN AN R11 FLOODED EVAPORATOR. THREE DIFFERENT BOILING SURFACE GEOMETRIES ARE EVALUATED: INTEGRAL FINS, AND 2 DIFFERENT HIGH-PERFORMANCE ENHANCED BOILING SURFACE GEOMETRIES FOUR WATER-SIDE SURFACE GEOMETRIES ARE EVALUATED: A PLAIN SURFACE, A 10-RIDGE RIBBED TUBE, A 30-RIDGED RIBBED TUBE, AND A CORRUGATED TUBE. ANALYSIS IS PROVIDED TO DEFINE THE SHELL LENGTH REDUCTION FOR SPECIFIED OPERATING CONDITIONS, AND TO DEFINE HOW MUCH THE SATURATION TEMPERATURE MAY BE INCREASED FOR A BUNDLE OF FIXED SIZE.
