Question

This is a multiple-part question, I just need help with part C, Table 2.2 is provided and you can refer to above parts for equations and boundary equations.

1a. Consider the
problem 2-15 from Ozisik (1993). Starting with the
heat diffusion equation, Eq. 1-11a in Ozisik (1993), show how it can be reduced to:
a²T ²T
+
ax² ay²
in [0<x<a; 0 <y<b], subjected to the following boundary conditions:
ƏT
ax
ƏT
= 0 at x = 0;
T = f(x) at y = 0;
+ HT = 0 at y = b
All assumptions must be clearly stated and justified, and all steps clearly explained.
əx
= 0
+ HT= 0 at x = a;
ƏT
1b. Using separation of variables, show how the eigenfunction from Table 2-2 in Ozisik
(1993) was derived.
X(Bm,x) = cosmx
Each step of your formulation must be clearly explained, and all assumptions justified.
1c. Show how the eigen condition from Table 2-2 in Ozisik (1993) was derived.
Pm tan ßma = H
Each step of your formulation must be clearly explained, and all assumptions justified.
