TVM0031,Transportprocesser i flerfas reaktivt flöde, HP 7.5

ECTS/HP: 7.5

Course code: TVM0031

Educational level: third-cycle course

Entry requirements: Basic knowledge of thermodynamics, fluid dynamics, and programming languages (Matlab, Python, C++, or Julia) will be helpful, but not required.

Course content: The course aims to introduce basic knowledge of transport phenomena (momentum, heat, and mass transfer) occurring in multiphase reactive flows. The course focuses mainly on learning theoretical principles and solving problems (with pen and paper, as well as using numerical methods). The focus is laid on the application in multiphase reactive flows, especially including heterogeneous reactions and porous media.

The course contents include the following topics.

1. Overview of transport phenomena
2. Basic laws and transport properties
3. Steady-state solutions of 1D diffusion equations
4. Conservation equations and dimensional analyses
5. Multi-variable equations
6. Inter-phase transport phenomena
7. Macroscopic balances
8. Transport phenomena inside porous media
9. Heterogeneous reactions under heat and mass transfer limitations
10. Numerical simulation of reaction-transport problems

Learning outcomes:
Knowledge and understanding

After completing the course, you shall:

• have a broad basic knowledge of the driving forces for momentum, heat, and mass transport, and
• have a broad basic understanding of the theories and modelling methods applied in the modelling of transport phenomena.

Competence and skills

After completing the course, you can:

• estimate relevant transport parameters,
• select appropriate models for transport phenomena based on the conditions,
• conduct a simple analysis of reaction-diffusion or thermal-reaction systems,
• simulate reacting particles under the influence of transport phenomena, and
• evaluate the modelling errors.

Judgement and approach

After completing the course, you have an insight of:

• how to select appropriate models and parameters for transport phenomena, and
• the capability, limitation, and origins of errors in different models.

Course methods: A series of seminars will be held, where individual students or groups of students will present the summary of the contents covered for each session. A small number of calculation exercises will be given as assignments for each topic. Finally, the students will develop a model of a particle that is undergoing heterogeneous reactions driven by heat or mass transfer (e.g. biomass devolatilization, char combustion/gasification, calcination, ore reduction, and metal combustion). The results will be presented orally with short written reports. Majority of the course is conducted based on a book by Bird, Stewart, and Lightfoot, “Transport phenomena”.
