- Hi, Sirs,
- I have a question about if a Laplace equation
-
- div grad T = 0 in a smooth enough domain,
-
- is well-posed under following boundary condition:
-
- - dT/dn = a ( T*T*T*T - c), on the domain boundary,
-
- (note: T*T*T*T means T to the fourth power.)
- where n is in the direction of outward unit normal along the boundary,
- a, c is constant, and a>0.
-
- This boundary is equivalent to a radiation along boundary; heat
- conducted from the domain is radiated to out side environment.
-
- Can anybody prove that the problem is well-posed?
-
- If possible, please reply to this account directly. Thanks.
-
- JTR Smith
