numerical methodology, physical modelling and practical use of Computational Fluid Dynamics (CFD) and the Finite Volume Method of discretisation for continuum mechanics applications

Lecturer: Prof. Hrvoje JASAK, University of Zagreb

1) Course Overview

The course aims to provide the basics of numerical methodology, physical modelling and practical use of Computational Fluid Dynamics (CFD) and the Finite Volume Method of discretisation for continuum mechanics applications.

2) What courses & programmes must have been taken before this course?

Mathematics, Fluid Dynamics, Thermodynamics

3) What other courses must be taken with this course?

None

4) Course Description

The course shall cover the basic principles of continuum mechanics and physical modelling in fluid flow simulations. The objective of the course is to provide the user with sufficient background knowledge to understand the principles of physical modelling and numerical techniques needed to use a CFD package in solution of industrially relevant cases.

5) Course Outcome

On completion of the course, attendees shall be able to create a computational mesh using commercial or open source tools, set up a numerical simulation for a steady and transient fluid flow in a complex geometry, produce a solution and interpret results in a meaningful way.

6) Course Tools

Practical CFD work within the course shall be performed using OpenFOAM, a popular open source CFD package.

This course will involve fundamentals of continuum mechanics partial differential equations (PDEs), issues related to structure and generation of a Finite Volume type computational mesh, introduction to computational linear algebra, discretisation techniques and numerical schemes to solve PDE problems, and an overview of numerical procedures for the solution of coupled equation sets. Relevant physics models for steady and transient turbulent fluid flow and heat transfer shall also be reviewed. Hands-on sessions with OpenFOAM shall be used to develop practical CFD skills of attendees.

7) Contact Teaching Time

Lecture duration: 8-10 hours

Practical exercises: 6 hours

Student project (home work): 20 hours

8) Assessment

Course assessment shall be performed using a combination of oral examination and student project.
