摘要：

Dynamics of physical phenomena are modeled by ordinary differential equations and partial differential equations, where the solutions are typically not easy to find. A recent trend is to solve these equations by some data-driven approaches through machine learning, such as Gaussian processes or neural networks. Physics-informed neural networks (PINNs) are a type of neural networks that incorporate physical laws or principles into their architectures, thus forcing the neural network prediction to abide physical laws. In this talk, I will discuss a 3D printing process called direct ink writing (DIW) and how PINNs can be used for predicting the fluid flow inside printer nozzle, which directly affects the quality of the 3D printing process. I will discuss several neural network architectures and compare their performance.
