- Homework Statement
- Consider a cylinder of radius a and height H. The base of the cylinder is at z=0 and the top is at z=H. Find a function which satisfies ∂U/∂t = k(nabla)^2U in the domain and stated boundary conditions and initial conditions.
- Relevant Equations
- * ∂U/∂t = k∇^2U
* Boundary condition: U=0 on the surface of the cylinder at all times.
* Initial condition: U within the domain = α(r)β(z) at time t=0 where α(r)=e^-r
The function should use (r,z,t) variables
The domain is (0,H)
Since U is not dependent on angle, then theta can be ignored in the expression for Laplacian in cylindrical coordinates(?)
