Basics of heat and fluid flow modeling – workshop for non-CFD professionals, Jun 2019, Poland

Posted By: Wojciech Regulski
Date:Thu, 2 May 2019, 5:56 p.m.

Poland, June 10, 2019

The course introduces the basics of the numerical heat
and fluid flow modelling to
engineers who are new to this field or CFD simulations
are not their main
occupation. The workshop consists of the theoretical
(physics+numerical models), review
and practical part with hands-on computer exercises.
In contrast to the standard CFD-software vendor
workshops, we focus on the general idea
of flow modelling rather than the operation of the
specific software.




June 10th, Monday:

9:00-9:30 Fundamental models and equations of heat and
fluid flow

9:30-11:30 Review of modelling techniques:
- heat conduction and convective heat transfer
- flows through filters and porous materials
- basic discretisation techniques: Finite Difference

11:30-13:00 Finite Element and Finite Volume methods:
- basic information
- numerical stabilisation techniques
- the concept of the numerical diffusion and its impact
on the accuracy

13:00-14:00 Lunch break

14:00-17:00 Practical exercises using a basic CFD package
- modelling of heat conduction
- modelling of laminar flow with heat transfer

19:00 Social event

June 11th, Tuesday:

09:00-10:00 Details of numerical techniques – solving
non-linear systems of equations

10:00-11:30 Computational mesh vs numerical solution –
how a mesh can skew reality

11:30-12:30 Turbulence modelling:
- RANS equations – basic concepts
- critical mesh quality criteria
- explanation of the y+ parameter

12:30-13:00 Overview of advanced techniques:
- optimization & sensitivity study
- fast numerical models
- High-Performance Computing (HPC)

13:00-14:00 Lunch break

14:00-16:00 Practical exercises using a simple CFD
package #2:
- modelling of turbulent flows

16:00-17:00 Extra questions & consultation of the
participants’ engineering problems

After participating in the workshop, you will:
- have a better understanding of the methods used for
heat and fluid flow modelling (FD/FVM/FEM)
- be able to run simple CFD simulations on your own
be able to judge the quality of mesh and simulation
- understand the limitations of CFD modelling
obtain a certificate of attendance

Background in physics, mathematics or engineering and
a rudimentary understanding of numerical modelling
