CAS Computational Fluid Dynamics

Do you want to gain a competitive advantage by optimising your products and processes? Are complex experimental studies too time-consuming and cost-intensive for you? By optimising flow characteristics through Computational Fluid Dynamics (CFD), the design and functionality of your products and processes can be improved quickly and cost-efficiently.

PlaceUniversity of Applied Sciences Rapperswil (HSR), next to the train station "Rapperswil", Switzerland

    The vocational training CAS Computational Fluid Dynamics consists of the following three modules, which can also be attended separately and for which ECTS credits are awarded with the final certificates:

    • Mathematics and Computational Methods:
      The mathematical basis for simulations.
    • Fluid Dynamics, Heat Transfer and Turbulence Modelling:
      The physics of flows.
    • CFD in Practice:
      Application of a CFD simulation to a real problem at your company.

    By completing the CAS Computational Fluid Dynamics you will receive 15 ETCS credits. This correlates to 144 hours of teaching time. Additionally you will be expected to spend around 150 hours preparing for the lessons and the exams as well as 90 hours for your personal project.

    Content of this on-the-job vocational training

    If you want to be proficient in simulation processes, you will soon learn that flow simulations are far more than just the application of simulation software. You need to understand the underlying laws of physics and how these laws can be applied using computational numerical methods. This is the only way to be able to detect errors in the process effectively and to assure the quality of the simulation results.

    Module A: Best Practice in CFD

    The successful application of flow simulations to real problems in your company requires a lot of experience. Our lecturer helps you learn the best way to transfer your knowledge gained from the other modules from theory into practice:

    • Simulation processes: modelling, meshing and validation.
    • Typical sources of errors.
    • Available CFD software.
    • Success stories.

    CFD project

    Bring your own problem from your professional environment and work on it with CFD simulations in a defined project, which will be supported by our experts. This way you can apply the knowledge you learn in the other modules directly and guarantee the transfer of your knowledge from theory into practice. The project includes:

    • Definition of the problem.
    • Modelling and simulation with the help of CFD software.
    • Validation, evaluation, interpretation and presentation of the results.


    • You are able to assess the possibilities, error sources and limitations of CFD simulations and evaluate its quality.
    • You know how to apply CFD simulations to a real problem from your company.
    • You are able to evaluate and present the value of the simulation results with regard to your problem.


    Module B: Fluid Dynamics, Heat Transfer and Turbulence Modelling

    Fluid DynamicsFlows obey the laws of fluid dynamics. You will learn these laws and gain insights into their complexity. Additionally you will discover the influence of boundary layers, turbulence and compressibility. This part of the module consists of:

    • Terms and definitions.
    • Dimensional analysis.
    • Conservation equations (Navier-Stokes equations).
    • Boundary layers, turbulent flows and compressibility.
    Heat Transfer

    In many fluid applications, thermodynamic processes play an important role. You will get to know different models for simulating thermodynamic and fluid dynamics problems. This part of the module includes:

    • Heat conduction, heat transfer and conjugate heat transfer.
    • Convection.
    • Radiation and radion models.

    Turbulence Modelling


    Turbulence refers to are small-scale vortices in a flow. You learn how turbulence influences the flow and why turbulence modelling is still such a challenge. This part of the module involves:

    • Characteristics of turbulent flows.
    • Statistical description of turbulence (Reynolds-Averaged Navier-Stokes equations).
    • Turbulence modelling: available models with their pros and cons.
    GoalsThe learning targets of the three parts of this module are:

    • You are aware of the most important physical properties of flows.
    • You understand the influence of thermal energy on flow.
    • You recognise the challenges of turbulence modelling and you know how to apply the available turbulence models correctly.


    Module C: Mathematics and Computational Methods

    Flow simulations are based on numerical solutions of partial differential equations (PDE). In this module you will elaborate on the mathematical concepts for understanding PDEs and get to know different numerical methods for solving such equations computationally. This module includes:

    • Systems of ordinary differential equations.
    • Partial differential equations: classification and key examples.
    • Numerical solutions to systems of equations.
    • Numerical solutions of differential equations.
    • You understand the mathematical basis for the appropriate physical laws.
    • You have learnt various numerical methods for solving the equations describing these laws.

    With hands-on learning to success

    Everyone learns differently. At HSR we pay special attention to a well-balanced mix of learning methods:

    • Lectures and presentations: Sharing of knowledge.
    • Exercises and examples: for the application and deepening of knowledge.
    • Supported project work: CFD analysis of a real problem at your company with support from our experts.
    • Presentations and inputs from external experts.
    • Self-study.

    You will deepen your knowledge independently in groups or self-study.


      Experts from industry, academia and research teach you in the complex fluid dynamics. They continuously adapt the content of their lessons to the most current technological developments. You benefit from the high practical orientation, which is guaranteed by the lecturers and by your own personal project.

      This vocational training was designed by professors from the University of Applied Sciences Rapperswil (HSR) in close collaboration with experts from the industry. The knowledge transfer between the university and the students is the key goal.

      Our lecturers guide you through the whole simulation process with their practical experience and in-depth knowledge.
