Internship | Physics-informed neural networks for fluid dynamics

About this position

Want to contribute to innovative solutions for complex multi-physics problems? Join us in applying physics-informed machine learning to case studies in the energy sector. Physics-informed machine learning holds the promise to combine the best of two worlds: (i) it uses machine learning to extract complex relationships from a dataset and to create a fast model, and (ii) it ensures that physics-based theories are satisfied, and reliable predictions can be made even in ‘unseen’ regimes (for parameters not contained in the ‘training’ dataset). In this project, this innovative approach will be applied to complex fluid behavior within pipes.

What will be your role?

Physics-informed neural networks (PINNs) are neural networks with a loss function forcing the NN to satisfy predefined laws (typically, conservation equations in the form of ODEs/PDEs). PINNs can be used to support traditional numerical methods (such as computational fluid dynamics, CFD) and speed-up design and optimization studies; they can handle ill-defined problem (for example when boundary conditions are not clearly defined) and directly incorporate noisy experimental data in the model; they can be used for model calibration or inverse problems, when some parameters of the underlying equations are unknown and need to be discovered using the available data.

We are using PINNs for applications in different domains, and in this project the focus will be on complex fluid behavior within pipelines. Particularly, the aim is to model viscoelastic turbulent flow to identify optimal operating conditions to maximize drag reduction. We envision to apply this methodology for applications in the context of geothermal production and district heating.

In consultation with the student and academic advisor, exact project scope and duration will be defined. Minimum project duration is 3 months. Within TNO, you will work in contact with an international team of highly motivated researchers in the Heat Transfer and Fluid Dynamics department in Delft; partial work from home is possible.

What we expect from you

You are in the final stages of your degree in engineering, physics, mathematics and have some track record in modelling and/or machine learning. You have experience in programming in Python, good communication skills (including in English), you have the right mix of curiosity-driven motivation and result-oriented mentality.
