| Aim: To enable the students to develop and use computer based methods in numerical simulation of thermal processing of materials. |
Contents: Lectures: Numerical methods for simulation of thermal processing of materials especially the control volume based finite difference method and the finite element method. Thermal resistance. Formulation in polar co-ordinates. Explicit and implicit algorithms. Stability analysis. Crank-Nicholson's method and the ADI method. Analytical solutions based on the error function. Riemann temperature. Heat transfer coefficients. Algorithms for the release of latent heat, Scheilīs, Brody-Flemingsī and Clyne-kurzīmodels. Modelling of thermal and mechanical fields in welding.Thermal stresses and deformations in casting. Determination of material data. Inverse modelling.
Exercises: Development and programming of algorithms for simulation of thermal processing of materials, especially casting. The first part of the exercises which is compulsory, consists of modelling of solidification of a sand casted plate. The result are compared with measurement. During the second part the students choose a small modelling project within the field of thermal processing of materials. |
