Resumo :

ABSTRACT: THIS WORK PRESENTS A STUDY OF THE NATURAL
CONVECTION PROCESS IN AN ANNULAR CAVITY LOCATED BETWEEN TWO
CONCENTRIC CYLINDERS FOR SEVERAL RELATIONS OF EXTERNAL AND
INTERNAL RADIUS FOR A RAYLEIGH NUMBER, BASED ON INTERNAL RADIUS,
OF 10^3. THE SOLUTION FOR THE PROBLEM IS OBTAINED BY A FINITE
ELEMENTS METHOD WITH EQUAL ORDER FOR THE PRESSURE AND VELOCITY
FIELDS. THE RESULTS WERE COMPARED WITH OTHER NUMERICAL RESULT AND
GOOD AGREEMENT WAS FOUND. FIGURES FOR SEVERAL RATES OF EXTERNAL
AND INTERNAL RADIUS ARE PRESENTED AND DISCUSSED.
KEY-WORDS: NATURAL CONVECTION, ANNULAR GEOMETRY,
FINITE ELEMENTS |
