Fuzzy Finite Element Solution of Uncertain Convection-Diffusion Heat Transfer for a Rectangular Plate

Convection-diffusion of heat transfer is one of the important phenomena in fluid flow and industrial problems. The involved parameters, boundary conditions, and material properties are greatly affecting the same. As such, the uncertainness of these parameters, conditions, and properties cannot be ignored. Therefore, the present research work focuses numerical approach to study the uncertain convection-diffusion of heat transfer problem. Here, the finite element method is employed with fuzzy uncertainties to investigate the uncertain temperatures for a plate problem. The uncertainty is considered with a 10% of error and then corresponding fuzzy numbers are generated. These fuzzy numbers are used in the governing differential equation and boundary conditions to get the nodal temperatures. A different combination of fuzzy parameters is considered and the obtained results are reported. Furthermore, the sensitiveness of these parameters is reported in a case study.
