Summary

LOCAL NUSSELT NUMBERS FOR LAMINAR MIXED CONVECTION FLOWS ALONG ISOTHERMAL VERTICAL, INCLINED, AND HORIZONTAL FLAT PLATES ARE PRESENTED FOR THE ENTIRE MIXED CONVECTION REGIME FOR A WIDE RANGE OF PRANDTL NUMBERS. SIMPLE CORRELATION EQUATIONS FOR THE LOCAL AND AVERAGE MIXED CONVECTION NUSSELT NUMBERS ARE DEVELOPED. THE THRESHOLD VALUES OF SIGNIFICANT BUOYANCY EFFECTS ON FORCED CONVECTION AND FORCED FLOW EFFECTS ON FREE CONVECTION, AS WELL AS THE MAXIMUM INCREASE IN THE LOCAL MIXED CONVECTION NUSSELT NUMBER FROM THE RESPECTIVE PURE CONVECTION LIMITS, ARE ALSO PRESENTED. THE BUOYANCY OR FORCED FLOW EFFECT CAN INCREASE THE SURFACE HEAT TRANSFER RATE FROM PURE FORCED OR PURE FREE CONVECTION BY ABOUT 20%.
