Characterization of a capillary driven flow in microgravity by means of optical technique
Domenico Fiorini, Louis Carbonnelle, Alessia Simonini +3
The motion of a gas-liquid interface along a solid wall is influenced by the capillary forces resulting from the interface's shape and its interaction with the solid, where it form…
Damping of three-dimensional waves on coating films dragged by moving substrates
David Barreiro-Villaverde, Anne Gosset, Marcos Lema +1
Paints and coatings often feature interfacial defects due to disturbances during the deposition process which, if they persist until solidification, worsen the product quality. In…

This chapter reviews the fundamentals of continuous and discrete Linear Time-Invariant (LTI) systems with Single Input-Single Output (SISO). We start from the general notions of si…
A 1D Model for the Unsteady Gas Dynamics of Ejectors
Jan Van den Berghe, Bruno R. B. Dias, Yann Bartosiewicz +1
We propose a 1D unsteady model for supersonic single-phase ejectors. The model treats an ejector as a pipe network with two inputs and one output and combines a 1D gas dynamics for…
Linear and Nonlinear Dimensionality Reduction from Fluid Mechanics to Machine Learning
Miguel A. Mendez
Dimensionality reduction is the essence of many data processing problems, including filtering, data compression, reduced-order modeling and pattern analysis. While traditionally ta…
