ANALYSIS OF LAMINAR FORCED CONVECTION IN ANNULAR DUCTS USING INTEGRAL TRANSFORMS
|
|
Summary :
|
ABSTRACT. LAMINAR FORCED CONVECTION IN ANNULAR DUCTS IS ANALYZED BY USING THE GENERALIZED INTEGRAL TRANSFORM TECHNIQUE (GITT) TO SOLVE THE NAVIER-STOKES AND THE ENERGY EQUATIONS IN THE CYLINDRICAL COORDINATES SYSTEM. SOME CASES INVOLVING DIFFERENT ASPECT RATIO, GIVEN BY THE RELATION BETWEEN INTERNAL AND EXTERNAL DUCT DIAMETERS, AND FOR PRANDTL NUMBER PR=0.7, ARE MORE CLOSELY CONSIDERED IN THE STUDY. NUMERICAL RESULTS ARE OBTAINED FOR LOCAL TEMPERATURE PROFILES, BULK MEAN TEMPERATURE AND LOCAL NUSSELT NUMBER. COMPARISONS WITH PREVIOUS RESULTS IN THE LITERATURE ARE PERFORMED TO VALIDATE THE PRESENT SIMULATION.
KEYWORDS: FORCED CONVECTION, NAVIER-STOKES EQUATIONS, ANNULAR DUCTS, INTEGRAL TRANSFORM
