Unformatted text preview: heat transfer coefficients on either side of the element. Again we are treating this in slab geometry. The governing equation is: The boundary conditions can be expressed as: the heat transfer into an interface from the solid must match the heat transfer out of the interface into the fluid. Because of the difference in interface orientation, this takes a slightly different form on the inner surface ( x = 0) than the outer surface ( x = t ): Here h and h t refer to the heat transfer coefficients at x = 0 and x = t respectively. 3. 5-5, El-Wakil; Note: The flux shape in a spherical reactor is, per Table 3-2, page 59 of El-Wakil, 4. 5-8, El-Wakil...
