SOLUTION FOR THE THERMAL ENTRY REGION IN LAMINAR FLOW OF BINGHAM PLASTICS WITHIN ANNULAR DUCTS VIA INTEGRAL TRANSFORMATION
|
| |
|
Summary :
|
|
ABSTRACT. THE THERMAL ENTRY REGION IN LAMINAR FLOW OF BINGHAM PLASTICS WITHIN CONCENTRIC ANNULAR DUCTS IS SOLVED ANALYTICALLY THROUGH THE CLASSICAL INTEGRAL TRANSFORM TECHNIQUE. BOUNDARY CONDITIONS OF FIRST KIND ARE PRESCRIBED EITHER AT INNER OR OUTER WALL DUCT IN ORDER TO VERIFY THE EFFECTS ON THE TEMPERATURE FIELD IN THE FLUID. NUSSELT NUMBERS ARE CALCULATED ALONG BOTH THE THERMAL ENTRY AND FULLY-DEVELOPED REGIONS WITH HIGH ACCURACY FOR DIFFERENT YIELD NUMBERS AND ASPECT RATIOS WHICH ARE SYSTEMATICALLY TABULATED AND GRAPHICALLY PRESENTED.
KEYWORDS: BINGHAM PLASTICS; ANNULAR DUCTS; INTEGRAL TRANSFORM. |
