Frank and Ora Lee Marble Professor of Mechanical Engineering
California Institute of Technology
Winner of the 2022 ASME Freeman Scholar Award
Biography: Prof. Tim Colonius and his research team use numerical simulations to study a range of problems in fluid dynamics, including aeroacoustics, flow control, instabilities, shock waves, and multiphase flows. Prof. Colonius also investigates medical applications of ultrasound and is a member of the Medical Engineering faculty at Caltech. He and his group have made pioneering contributions in multiple areas. These include theoretical and computational aeroacoustics, particularly the development of accurate numerical simulations of sound generation and understanding the role of coherent turbulence structures in noise radiation from jets. They have also made fundamental contributions to modal decomposition of fluid flows and reduced-order modeling of coherent structures. They have developed robust interface-capturing numerical schemes for compressible multiphase flows and used these schemes to study a variety of applications of multiphase flow including cavitation and bubble dynamics and droplet aero-breakup. Prof. Colonius is an author of more than 300 papers, and is the editor-in-chief of the journal Theoretical and Computational Fluid Dynamics.
Prof. Dr.-Ing. Paul Uwe Thamsen
Professor Fluid System Dynamics
Technical University Berlin
Winner of the 2022 ASME Henry R. Worthington Medal
Biography: Prof. Dr.-Ing. Paul Uwe Thamsen’s education (1980-1992) at Pfleiderer-Institute Braunschweig focused on: pump design, experimental investigations, cavitation measurements, submersible pump development finalized in doctorate research on "Operational behavior of submersible pumps with inlet distortions". During the industrial time (1992 – 2003) at Pleuger Worthington GmbH in Hamburg (Ingersoll Dresser Pumps /Flowserve), his responsibility was for R&D, engineering, marketing and sales, general management - always involved in technical development as a hydraulic/technical expert for a lot of projects. Final position was general manager and technical director for submersible pumps worldwide. During this time, developed a couple of successful new pump lines and built challenging projects (e.g. large water projects, multiphase subsea, mining, offshore).
Since 2003, he is a professor for fluid system dynamics at Technical University Berlin, focusing on fluid mechanic, fluid flow machines and fluid infrastructures. Main research topics are on centrifugal pumps, water and wastewater, automation & digitalization and medical applications. A strong cooperation with industry results in innovative products and new control methods for pump operation. A lot of results are published in new standards for pumping station design a pumping infrastructure in the field of wastewater pumping, decomposition of fluid flows and reduced-order modeling of coherent structures. They have developed robust interface-capturing numerical schemes for compressible multiphase flows and used these schemes to study a variety of applications of multiphase flow including cavitation and bubble dynamics and droplet aero-breakup. Prof. Colonius is an author of more than 300 papers, and is the editor-in-chief of the journal Theoretical and Computational Fluid Dynamics.
