Consider a two- dimensional, straight triangular fin of Length L= 50mm and base thickness t= 20mm. The thermal conductivity of the fin is k= 25 W/mK. The base temperature is T_b= 50 degrees Celsius, and the fin is exposed to convection conditions characterized by h= 50 W/m^2 K. T_infinity= 20 degrees Celsius.
1) Using the finite difference mesh delta x= 10mm and delta y= 2mm, and taking advantage of symmetry, determine the fin efficiency.
2) Make a temperature contour plot using MATLAB
