EFFECTS OF WALL RADIATION AND CONDUCTION ON THE STABILITY OF A FLUID IN A FINITE SLOT HEATED FROM BELOW.

Author(s) : HATFIELD D. W., EDWARDS D. K.

Type of article: Article

Summary

THE THERMALLY EXPANSIVE, RADIATIVELY DIATHERMANOUS FLUID IS HEATED FROM BELOW AND COOLED FROM ABOVE AT RIGID ENDS. THE ENDS HAVE ARBITRARY BUT EQUAL EMISSIVITY. THE VERTICAL WALLS ARE THIN AND CONDUCTING, HAVE ARBITRARY UNIFORM EMISSIVITY, AND ARE ADIABATIC ON THEIR EXTERIOR SURFACES. EFFECTS OF ASPECT RATIO, SIDE WALL CONDUCTANCE, AND SIDE AND END WALL EMISSIVITIES ON CRITICAL RAYLEIGH NUMBER ARE FOUND ANALYTICALLY WITH THE GALERKIN TECHNIQUE AND CONFIRMED EXPERIMENTALLY WITH HOLOGRAPHIC INTERFEROMETRY.
