Modelling of Urban Flows

This course is part of the larger module ENVM1800 "Atmospheric Measurements and Modelling". Students Environmental Engineering within the AEE track follow the larger module ENVM1800.

Other students can follow this course as an elective. Please consult the responsible instructor if you are interested. Please join ENVM1800 on Brightspace.

The course focuses on the fundamentals of Computational Fluid Dynamics (CFD) tailored for urban environments. The course will introduce the governing equations first and elaborate on the mathematical methods applied to model the flow around buildings. Real world examples will be used to show direct application of CFD during computer labs, and students will have hands-on practice to learn and use CFD in urban areas.

The following topics will be addressed:

• Governing equations

• Reynolds decomposition and averaging

• Discretization of governing equations (finite-difference, finite-volume, finite-element approaches)

• Time-marching methods

• Stability, accuracy, convergence

• Boundary conditions for urban environments

• Mesh and complex geometries generation

• Turbulence modelling (RANS/LES/DNS)

• Introduction to uncertainty quantification

Formative feedback during in-class activities, with interaction between peers. Formative assignments will be proposed to the students during laboratories, with feedback provided within 2 weeks. During the first week, their peers will have the opportunity to provide feedback. During the second week, the teacher will provide feedback.

Summative assignment: Assignment including report and presentation.

A successful completion of the course requires a minimum grade of 5,8 per Exam/Assessment.
