Flow Science and Engineering

Faculty of Mechanical and Aerospace Engineering ITB

Research

Flow Science and Engineering Laboratory focuses on four different subjects of research including computational aeroscience, data-driven fluid mechanics with machine learning, experimental fluid mechanics, and intelligent computer vision. Computational aeroscience utilizes existing CFD software in analyzing flow properties and develops in-house solver for fluid problems. Data-driven fluid mechanics has become a topic of interest since the first time, where a variety of sophisticated methods such as Physics Informed Neural Network and Gaussian Process have been implemented on thermo-fluid and solid mechanics problems. Experimental fluid mechanics practice experiments on various flow visualization and analysis, as well as biomimetic propulsion system. Research topics on computer vision focused on the explainability of machine learning-based classifications in engineering and medical applications.
