STUDY OF THE ASPECT RATIO EFFECT IN A THERMALLY-DRIVEN OPEN CAVITY
|
| |
|
Resumo :
|
|
NATURAL CONVECTION IN A THERMALLY-DRIVEN OPEN CAVITY IS ANALYSED NUMERICALLY.
THE VERTICAL WALL IS HEATED AND THE HORIZONTAL WALLS ARE ADIABATIC. THE OTHER VERTICAL WALL
IS OPEN TO A UID RESERVOIR. LAMINAR AND TWO-DIMENSIONAL OW IS ASSUMED FOR RAYLEIGH
NUMBER RANGING FROM 10
3
TO 10
7
. THE UID IS APROXIMATELY AIR WITH PRANDTL NUMBER XED
AT 1.0. THE PROBLEM IS SOLVED NUMERICALLY BY USING THE FINITE VOLUME-SOLA METHOD.
THE AVERAGE NUSSELT NUMBER IS REPORTED FOR DI ERENT VALUES OF THE RAYLEIGH NUMBER. THE
ASPECT RATIO OF THE OPEN CAVITY IS DONE AS L=H = 0.5, 1.0, 3.0 AND 6.0, WHERE L IS THE
CAVITY WIDTH AND H IS THE CAVITY HEIGHT. THE MAIN CHARACTERISTICS OF THE OW AND THE HEAT
TRANSFER PROCESS IS DISCUSSED.
KEY-WORDS: NATURAL CONVECTION, ASPECT RATIO EFFECT, OPEN CAVITY |
