How to Find Temperature Distribution in a Rectangular Sheet?

Click For Summary
SUMMARY

The discussion focuses on finding the temperature distribution in a rectangular sheet under specific boundary conditions: U(0, y) = U(a, y) = U(x, b) = 0 and U(x, 0) = f(x). The solution utilizes the Fourier series representation, specifically the equation U(x, y) = Σ B sin((nπx)/a) sinh((nπy)/a). A proposed modification to the formula suggests U(x, y) = Σ B sin((nπx)/a) sinh((nπ(b - y))/a) to accommodate the boundary conditions. The use of LaTeX for clarity in mathematical expressions was also highlighted.

PREREQUISITES
  • Understanding of Fourier series and coefficients

Homework Statement



Find the temperature distribution in the rectangular sheet given the following boundary conditions:

U(0, y) = U(a, y) = U(x, b) = 0; U(x, 0) = f(x)


Homework Equations



U(x, y) = (summation) B (fourier coefficient) [sin ((n*pi*x)/a) sinh ((n*pi*y)/a)]



The Attempt at a Solution



Wouldn't it just be a simple modification of the above formula:

U(x, y) = (summation) B [sin ((n*pi*x)/a) sinh ((n*pi*(b - y))/a)

I can't help you solve it. However, I will bump it by retyping it with LaTeX for you :-)

U\left(x,y\right)=\sum B\sin{\left(\frac{n \pi x}{a}\right)}\sinh{\left(\frac{n\pi(b-y)}{a}\right)}
