Eligibility:


In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

Course specific prerequisites

At least one basic course in transport phenomena
KAA060 Transport Phenomena in Chemical Engineering, 7.5 hec
MTF052 Fluid Mechanics, 7.5 hec
Or similar course.

Aim

The course gives an introduction into advanced modeling using Computational Fluid Dynamics (CFD), which has become a indispensible tool for many engineers. The focus is on modeling the interaction between convection, diffusion, heat conduction and chemical reactions for single phase and multiphase flows. The focus is to teach how to do CFD analysis correctly but not how to write your own CFD code. The student is given hands-on experience of drawing, meshing and simulation. One important objective is to give the students a critical attitude to both identify the possibilities and the limitations in advanced simulation programs. After completing the course the student will be able to select appropriate models and perform advanced simulations in accordance with best practice guidelines.

Learning outcomes (after completion of the course the student should be able to)

  • Understand basic principles of turbulence, mixing, fast reactions (combustion), multiphase flows and how these are related.
  • Understand the basics and limitations with the models used in CFD and select appropriate models for these systems.
  • Solve problems related to the systems above by selecting suitable models and numerical methods.
  • Provide the students with hands-on experience with a state of the art CFD program.
  • Critically evaluate simulation results and communicate the results in oral and written form.

Content

The course presents the fundamental equations for momentum, mass and heat balances and shows how these models are solved in commercial codes. The standard numerical methods are presented and their reliability is discussed. Elementary Computer Aided Design (CAD) and meshing are introduced. The properties of turbulent flows and how they are modeled by k-e, Reynolds stress and LES are described. Multiphase flows are very common in chemical engineering and the Euler-Lagrange, Mixture (Algebraic Stress), Euler-Euler and the Volume of Fluid (VOF) models are presented. Models for mixing and fast reactions in turbulent flows are described. CFD has both possibilities and limitations and the concepts of verification and validation are discussed. The tutorials give an introduction of how to formulate a CFD problem and set up and solve the problems in a commercial code.
The tutorials cover flow and reactions inside a porous catalyst, combustion in non-premixed flow and multiphase simulation of evaporation spray.
The project deals with the design of an industrial-scale selective catalytic reduction system and allows the student to explore various design improvements and apply best practice guidelines in the CFD simulations. Here the concept of virtual prototyping is introduced and the students can test different designs to find an optimal design.

Organisation

The course includes lectures, and 3 tutorials and one project. A commercial CFD program will be used in the course. The aim of the computer-based design project is to provide students with the opportunity of the practicing problem-formulation and problem-solving through the use of an advanced CFD program. A written report from each of the tutorials and the project that should contain a critical discussion of the models used in the simulation and an assessment of the reliability of the simulation.

Examination including compulsory elements

A written examination after about 4 weeks. The grades pass/fail are based on the written examination and written and oral reports from the tutorials and the project. Higher grades require also an extended project report and an oral examination.
