Type of article: Article

Summary

TWO-DIMENSIONAL CONVECTION IN A HORIZONTAL CAVITY OF HEIGHT D AND LENGTH L, DRIVEN BY DIFFERENTIAL HEATING OF THE TWO VERTICAL END WALLS, IS DESCRIBED. OF PARTICULAR INTEREST IS THE RANGE OF EXTERNAL PARAMETERS, AT LOW PRANDTL NUMBERS, FOR WHICH THE CIRCULATION CONTAINS A PARALLEL FLOW CORE. THE SIMPLE CORE SOLUTION, ASYMPTOTICALLY VALID AT SMALL ASPECT RATIO D/L, BREAKS DOWN EITHER AS END EFFECTS EXTEND INTO THE CENTER OF THE CAVITY, OR AS A SECONDARY SHEAR FLOW INSTABILITY DEVELOPS IN THE CORE ITSELF.
