In June 2026, Nicol\u00f2 Varallo served as an Invited Lecturer at the Okinawa Institute of Science and Technology (OIST), upon invitation from Prof. Marco Edoardo Rosti of the Complex Fluids and Flows Unit. Nicol\u00f2 Varallo delivered 20 hours of teaching within the PhD course (1 CFU) \u201cHands-On CFD Modelling: Mesh, Solve, and Analyze Complex Flows in ANSYS Fluent.\u201d<\/p>\n\n\n\n
The course provided an introduction to applied Computational Fluid Dynamics (CFD) for the modelling of complex engineering flows. Through a combination of theoretical lectures and hands-on sessions, Nicol\u00f2 Varallo guided students through the complete numerical simulation workflow, from mesh generation and case setup to solution and post-processing. Particular attention was devoted to high-quality 2D and 3D mesh generation, the definition of appropriate numerical models and boundary conditions, and the analysis and validation of numerical results against experimental data.<\/p>\n\n\n\n
As part of the teaching activities at OIST, Nicol\u00f2 Varallo also delivered the seminar \u201cExperimental and Numerical Characterization of Multiphase Flows for CO\u2082 Capture in Bubble Columns: From Local Dynamics to Global Flow Behaviour\u201d on June 10, 2026.<\/p>\n\n\n\n
During the seminar, Nicol\u00f2 Varallo presented research on the experimental and numerical investigation of gas\u2013liquid flows for CO\u2082 capture, adopting a multiscale perspective that connects phenomena occurring at the bubble scale with the overall fluid dynamics of bubble columns. The presentation addressed bubble shape and rising velocity, bubble size distribution and coalescence, as well as reactor-scale flow regimes and their transitions.<\/p>\n\n\n\n
Particular attention was also devoted to the use of ionic liquids for CO\u2082 absorption and to how their physicochemical properties can influence bubble dynamics and mass-transfer processes. Overall, the seminar highlighted the importance of linking local bubble-scale dynamics and large-scale fluid behaviour to improve the understanding and modelling of gas\u2013liquid systems relevant to CO\u2082 capture technologies.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
