Learning outcomes |
This course involves advanced concepts and techniques in fluid flow simulation, focusing on turbulence modelling, non-Newtonian fluid dynamics, and cutting-edge computational methods for complex flows. It aims to equip students with the theoretical foundation and practical skills needed to simulate, analyse, and interpret complex fluid phenomena in engineering applications.
-Deepen the understanding of turbulent flow theory.
-Introduce advanced turbulence modelling techniques, including RANS and LES.
-Explore numerical methods for compressible and shock-capturing flows.
-Examine the behaviour and simulation of non-Newtonian fluids, incorporating rheological concepts and constitutive models.
-Apply advanced CFD techniques to solve practical problems in engineering.

Teaching Methodologies and Assessment Criteria |
The evaluation consists of different differentiating elements duly linked to the syllabus of the curricular unit:
- Frequency Test, TF (11 Vs) on the theoretical-practical subject of the classes.
-Practical Laboratory Assignments, TP (5Vs) originating from the development of several computer codes in the classroom referring to the syllabus of the curricular unit.
- Mini-project work, PM (4Vs) which comprises the development of a more substantial code to solve a problem that is included in the UC program, to be developed by the student individually and outside the classroom.
