Acoustic and Flow Induced Vibrations: Industrial Systems

About The Course

Acoustic Induced Vibrations (AIV) and Flow Induced Vibrations (FIV) can cause piping systems to vibrate potentially resulting in fatigue failure. These excitation mechanisms are non-linear and strongly influenced by process conditions and pipework design such as mass flow rates and valve trims. Therefore, it can be difficult to predict the presence in new systems or the best remedial action in existing systems.

In this course, you will come to understand the physical concepts of both excitation mechanisms in detail and gain knowledge on strategies to overcome associated vibration issues in the field and reduce the risk when designing new systems. Next to relevant theory, high-risk systems, and codes & standards, a multitude of real-life cases are discussed including methods for troubleshooting AIV and FIV issues.

The course consists of 4 modules. All online training content is provided through your EngineeringTrainer account.

After the course, you maintain 1-year unlimited access to the course and the discussion forum. This allows you to perform modules again when you need to refresh the knowledge for your projects.

Prerequisites and level

  • A basic understanding of piping systems is beneficial
  • Level: Intermediate

Intended For

This course is designed for:

  • Engineers and technicians involved with solving vibration issues in existing piping systems,
  • Process and Piping engineers involved with designing new systems or maintaining existing systems.

Access to the self-paced course

After your purchase is confirmed you receive an account to the EngineeringTrainer online learning portal, where you can find the course in your dashboard. After opening the course you will be guided step-by-step through the different modules. You receive 1-year unlimited access to the course, allowing for the repetition of modules as desired.

Learn by doing

The self-paced and E-hybrid courses are mainly based on video content: video lectures and video software demonstrations. English subtitles are available and videos can be viewed as many times as desired. The video lectures help you to grasp the important technical concepts and in the video demonstrations the instructor uses the software and discusses all the steps and actions. You are recommended to follow the steps of the instructor in the software to optimize your learning curve.

The live sessions of the E-hybrid course are provided through MS Teams for which links are distributed from your course dashboard.

The classroom course is performed in person either on-site or in the Dynaflow Research Group office located in Rijswijk, The Netherlands. This course enables you to be face-to-face with the instructors with live examples provided. This course also provides all participants with a 1-year access to the self-paced course.

Participants of the self-paced and E-hybrid courses receive a personal digital certificate if they meet the following requirements:

  • Completion of each course module
  • Filling in the course evaluation survey

Participants of the classroom course receive a personal physical certificate upon the completion of the course.
