This course is organized by the Working Group on Trainsient Flows. It represents a historical event where the most senior professors and experts in transient flows are invited to deliver a 2h lecture on their field of expertise. This gives the opportunity to transfer the knowledge and best advices from our most respected and accomplished professors to the next generations of academicians and engineers.

This course provides a synthesis of several aspects of transient flows phenomena. It focuses on the fundamental physics and basic numerical and experimental approaches for the modelling of pressurized and free-surface hydraulic transients, as well as their practical engineering applications.

The course highlights the importance of understanding well extreme transient flows, such as the water hammer in pressurized conduits or the dam break phenomenon in free-surface flows, for the better application of advanced numerical codes. Experimental methods will be introduced and state-of-the-art instrumentation presented as key elements for the verification and validation of new modelling assumptions. Some of the phenomena associated to transient flows that need a better understanding are multi-phase flows, unsteady friction, pipe-wall material behaviour, fluid-structure interaction or cavitation. All these, together with their practical implications in engineering designs and infrastructure operations, will be tackled during this course with the support of real case studies.

Learning Goals

Upon completion, the participant should be able to:

• Recognize where and when transient flows might be relevant in water infrastructures.

• Understand the fundamental governing equations and the numerical schemes used as well as the underlying assumption for pressurized and free-surface transient flows.

• Comprehend dynamic phenomena not accounted for in the classic water hammer theory, namely multiphase flows, unsteady friction, pipe wall viscoelasticity, fluid-structure interaction, cavitation and geysering.

• Be familiar with transient based defect detection techniques.

• Expand the knowledge on cutting-edge instrumentation for the experimental description of transient flows.

For whom?

This course is intended for a broad audience. Whether you are a young professional or a senior, academic or practitioner, the course will help you to enhance your critical thinking about the consequences but also the great power of transient flows and how we can improve water systems performance and management.

Workload

The course is composed of 14 lectures. Starting from 31st of October, one lecture is given each day except on weekends. In total, the course is composed of 27h of lectures. A Professional Certificate of Attendance (PCA) is issued under request (Please see more details below).
