Kurzfassung
In search of efficient PINN architectures to reconstruct temperature fields from velocity vector data, we explore the usage of the dimensionless viscosity \nu = \sqrt(Pr/Ra) as trainable parameter of a PINN model. The results show that it improves the temperature reconstruction results. The estimation of the viscosity through the training can further be used as performance indicator, when an expected value is known.
