WebThe heat transfer cross-sectional area for longitudinal conduction is equal to the circumferential length of the parabolic segment S times the thickness of the parabola t. dL dL AC s*t (21) S is defined by equation (7) and α is the parabolic cir-cumferential segment angle. Ac from equation (19) becomes: Ac=S*t = aJĪPY*t Webbetween the metal foam samples were insignificant. The foam samples had higher heat transfer coefficient than the ball bearing sample but the wire mesh sample had the highest heat transfer coefficient. The heat transfer results for the wire mesh and ball bearing samples were compared with published data and good agreements were observed.
