Summary

NUMERICAL CALCULATIONS HAVEBEEN PERFORMED FOR 2 SETS OF BOUNDARY CONDITIONS: (I) AN ISOTHERMAL, HEATED BOTTOM PLATE WITH AN ISOTHERMAL, COOLED TOP PLATE ; AND (II) A UNIFORM HEAT FLUX AT THE BOTTOM SURFACE WITH AN ADIABATIC UPPER SURFACE. HEAT TRANSFER AND THE STRENGTH OF THE BUOYANCY-DRIVEN SECONDARY FLOW INCREASE WITH INCR EDT. FIN SPACING AFFECTS HEAT TRANSFER THROUGH CHANGES IN THE AXIAL VELOCITY DISTRIBUTION, THE STRENGTH OF THE SECONDARY FLOW, AND THE HEATEDSURFACE AREA, WITH DECREASED SPACING ACTING TO INHIBIT SECONDARY FLOW. EXPERIMENTS HAVE BEEN PERFORMED AND RESULTS ARE COMPARED TO PREVIOUS NUMERICAL PREDICTIONS, AND IT IS SHOWN THAT AGREEMENT IS GOOD UNTIL THE FLOW VIOLATES MODELLING ASSUMPTIONS OF STEADY, SYMMETRIC FLOW BETWEEN FINS.
