Type of article: Article

Summary

THE MEASUREMENT COVERED TOTAL MASS VELOCITY FROM 153 TO 194 KG/(M2.S) AND QUALITY FROM 1 TO 0.2 FOR THE DETERMINATION OF PRESSURE DROP, AND TOTAL MASS VELOCITY FROM 300 TO 600 KG/(M2.S) AND QUALITY FROM 1 TO 0 FOR THE FLOW PATTERN. THE MOST SIGNIFICANT FLOW PATTERNS WERE ANNULAR, FROTHY/SLUG, AND PLUG FLOW. THE FLOW REGIME MAP MODIFIED BY OSHINOWO WAS THE MOST REASONABLE OF THOSE PREVIOUSLY REPORTED. FURTHERMORE, THE FRICTIONAL PRESSURE DROP WAS PREDICTED FROM THE EXPERIMENTAL DATA. A DIMENSIONLESS EQUATION AND NOMOGRAPHIC METHOD FOR PREDICTION OF THE HEAT TRANSFER COEFFICIENT AND FRICTIONAL PRESSURE DROP DURING CONDENSATION INSIDE VERTICAL TUBES, BASED ON A HYDRODYNAMIC MODEL OF THE ANNULAR FLOW PATTERN AND TURBULENT ANALOGY, ARE PROPOSED.
