- Abstract
- We present a 1D ejector model with two streams which combines elements from existing models to reconcile pressure equalization, choking and shear. To this end, the compound choking theory is extended with a shear and friction force. Next, the model is calibrated on experimental and numerical data. Finally, we present a physics-constrained machine learning formalism to calibrate systems of ODEs with a neural network term.
