This project must be completed by writing a computer program using the language of your choice, but NOT Excel. The 1-D steady state diffusion for a fin is written as. The equation was derived in class. dxd(kdxdT)Ach,P(TTx)=00xL Compute the numerical solution to this equation using the finite volume method. The boundary conditions are: T(0)=TBq(L)=0DirichletNeumann With the following constants. TB=200C(Dirichlet,forall)T=100CT,0=200C(Robin,forgraduatestudents)L=1m The fin is circular with a diameter, d=8cmk=100W/mK,hm=50W/m2K. Use the Dirichlet boundary condition approximation. The tridiagonal coefficients are given by Eqns. 7.24, 7.29, and 7.56 for the interior, and left and right boundaries, respectively. See Example 3 in Chapter 7 for guidance. Assume constant mesh spacing for all calculations. Obtain solutions for 20,40, 80,120, and 360 celi meshes. The analytical solution is given by Eqn. 7.50. Plot the solution for each mesh, and the analytical solution for the finest mesh only on one groph. Your plots should be in non dimensional form of .vs, , with =Tm,0TTT,=x/L Actually since L=1m, and x have the same numerical value, but is unitless. - Plot ln(eL2) vs ln(x) for (a) on one graph. Compute the rate of convergence. Report: In your own words and equations (not cut and paste equations). 1. Present problem statement: governing equation, boundary conditions, and mathematical domain. 2. Present equations for tridiagonal coefficients for interior cell and each boundary cell. 3. Present results. 4. Discuss results. Number and reference every figure and/or table you put in your report
