Multiphase reactor modeling

1. Convection + reaction, 1D, steady state (1)

• Homogeneous 1D model without dispersion with first order reaction: ODE solver
• Homogeneous 1D model without dispersion with first order reaction: Finite differences

2. Convection + reaction, 1D, steady state (2)

• Homogeneous 1D models without dispersion, non-isothermal, multispecies with higher order reaction: extension

3. Convection + reaction + accumulation, 1D, unsteady state

• Unsteady 1D homogeneous model without dispersion

4. Diffusion + reaction 1D

5. External mass transfer (LDF)

6. Advanced mass transfer (1)

• Maxwell-Stefan: derivation + application to boundary layer

7. Advanced mass transfer (2)

• Maxwell-Stefan: mass transfer coefficients and flux correction factors

8. Axial dispersion

• 1D column model: convection-dispersion-reaction, heterogeneous, instationary

9. 2D models: uniform velocity

10. 2D models: velocity profiles


Additional information about the assessment

The group assignment will be done in groups of ca. 4 persons and the results will be addressed in a report written as a scientific journal publication (together with the developed computer code) and a group presentation. This will, together, constitute 70% of the final result. In addition to the modelling description (verification, validation and implementation) and discussion of the simulation results, the report is also evaluated on the information/organization of the sections, communicative quality and coherence, grammar and sentence structure and vocabulary, possibly partly in the form of a peer-review and/or external review. The final assessment also includes an individual oral examination (in total 30% of the final result). The individual oral examination will cover the assignment as well as all lectures and tutorials in order to assess the individual knowledge of the student. The result for the individual oral examination is required to be at least 5.0. A student that has participated in the course Multiphase reactor modeling (6EMA05),but has gotten a mark lower than 5.0 for the individual oral examination is awarded a 5 as final result, when the weighted average of the results yields a 5.5 or higher. The result of the assignment or oral examination is only valid in the study year in which the assignment has been carried out. Should the student have received a mark lower or equal to 5, the student will be given the opportunity to do a smaller additional individual assignment together with an individual oral examination.
