Overview

The students are introduced to the mathematical formulations of (1) linear elastic (structural), and (2) fluid flow (CFD) problems and their implementation into numerical schemes. Particular emphasis is placed on the Finite Element and Finite Volume Methods and the associated modelling strategies. Two detailed project exercises are carried out to support the course and highlight the importance of numerical simulations as an important, indeed, essential aid in engineering design.

Aims

The principal aim of this course is to introduce students to the principles and procedures involved in the numerical modelling of problems in linear elasticity and in fluid flow and heat transfer.

Syllabus

The Finite Element Method, as applied to structural problems, includes: formulations and setting up of system equations for one-, two-, and three-dimensional elasticity problems, their assembly, solution, and post-processing. The associated project requires the analysis of a plate with central hole using ABAQUS: studying the effect of element type, element density on computed values of deflections and stresses; convergent curves; stress discontinuities.

Application of the Finite Volume Method is concerned with the governing equations of thermo-fluids and numerical discretization of those transport equations; there is a brief treatment of turbulence modelling. The project involves turbulent flow and heat transfer in a mixing elbow. CFD solution and post-processing is undertaken using the ANSYS-FLUENT package.
