Description
Summary:The main propose of this research is to study the heat conduction of an aluminium metal bar in an undergraduate thermodynamics laboratory by using the Crank-Nicolson scheme of finite difference method. Heat conduction was simulated to find the thermal conductivity and was compared with the data obtained from the experiment and theory. In the performed boundary and initial conditions, it was found that the predicted thermal conductivity from the simulation was in agreement with those from the theory, however, it was slightly different from the experiment. These results can be used to improve method to find the thermal conductivity in the laboratory more accurately in the laboratory. Besides, these computational approaches can be an optional teaching method for studying thermal conduction for undergraduates, especially for a laboratory that has limited instruments.
