Despite its well-known ability in solving a fluid flow, the CFD method has several shortcomings,
including a rigorous meshing process and careful numerical method consideration,
which inevitably results in a trade-off between accuracy and computation time. In this
thesis, we have an interest in tackling these shortcomings by employing a machine learning
method called physics-informed neural network (PINN). In its early study, PINN shows capability
in solving several fluid flow problems. However, it is still in its infancy. To assess
PINN potential as an alternative flow field solver, this thesis studies the PINN capability
in terms of its formulations, hyperparameters, and configurations on several benchmark
flow problems that focus on accuracy and computation times metrics. Moreover, we also
performed an in-depth study about the transfer learning method that could accelerate the
PINN computation time, whereby is favorable specifically in design exploration. The results
concluded that PINN performed well in solving fluid flow by producing a good accuracy on
the benchmark problems. Furthermore, the transfer learning method significantly reduces
PINN computation time, even when engaged in different domain and boundary conditions.
