They act as gateways for the transfer of momentum, heat, and gases, playing a key role in everything from climate science to engineering applications. </span></font><span style="font-family:NimbusRomNo9L;font-size:14.666667px">One of the most striking examples is the exchange of CO₂ between the ocean and the atmosphere. This process, which happens daily, is heavily influenced by the behavior of bubbles and droplets in turbulent flows. </span></p><p style="margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><span style="font-family:NimbusRomNo9L;font-size:14.666667px">The size of these bubbles, the way they interact with the surrounding fluid, and the properties of their surfaces all determine how much gas is absorbed or released.</span></p><p style="margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><font face="NimbusRomNo9L"><span style="font-size:14.666667px">In this talk, Prof. Alfredo Soldati (TU Wien) will take us on a journey through the history and science of tracking interfaces in turbulent flows. He will introduce the latest mathematical models and computational techniques used to study how bubbles and drops evolve, particularly focusing on the phase-field method, which helps simulate how these interfaces move and interact over time.</span></font></p><p style="margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><font face="NimbusRomNo9L"><span style="font-size:14.666667px"><br></span></font></p><p style="margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><font face="NimbusRomNo9L"><span style="font-size:14.666667px">Beyond theory, Prof. Soldati will also showcase cutting-edge 3D experimental imaging techniques, which allow researchers to observe and analyze complex flow patterns with unprecedented detail. We will explore different flow conditions where surface tension, density, and viscosity change, revealing how these factors affect the behavior of bubbles and droplets. </span></font><span style="font-size:14.666667px;font-family:NimbusRomNo9L">A special focus will be given to the role of surfactants (substances that modify surface properties, such as soap in water) and how they influence turbulence, heat transfer, and the movement of dissolved gases between different fluid phases.</span></p><p style="margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><font face="NimbusRomNo9L"><span style="font-size:14.666667px"><br></span></font></p><p style="margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><font face="NimbusRomNo9L"><span style="font-size:14.666667px"><b>This lecture promises to be a fascinating exploration of how small-scale fluid dynamics shape large-scale environmental and industrial processes, making it relevant to scientists, engineers, and anyone curious about the hidden mechanics of the world around us.</b></span></font></p><p style="text-align:center;margin:0px;font-stretch:normal;font-size:11px;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><br></p><p style="text-align:center;margin:0px;font-stretch:normal;font-size:11px;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><br></p><p style="text-align:center;margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><span style="font-size:11px"></span></p></div></div></div></div></div><div style="line-break:after-white-space"><div dir="ltr"><div class="gmail_quote"><div style="line-break:after-white-space"><div><p style="text-align:center;margin:0px;font-stretch:normal;line-height:normal;font-size-adjust:none;font-kerning:auto;font-variant-alternates:normal;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-east-asian:normal;font-feature-settings:normal"><span style="font-size:11px"></span></p><div><div>_________________________________________________<br><br>Marco Marengo, PhD, MSc<br>_________________________________________________<br><br>Professor of Thermal Sciences<br>Department of Civil Engineering and Architecture<br>University of Pavia<br><br>Address:<span style="white-space:pre-wrap"> </span><span style="white-space:pre-wrap"> </span></div><div>via Ferrata 3, 27100, Pavia, ITALY<br>E-mail: <a href="mailto:marco.marengo@unipv.it" target="_blank">marco.marengo@unipv.it</a></div><div>Phone: +39 0382 985303</div><div>Mobile: + 39 3467427787</div><div><br></div><div><a href="https://web-en.unipv.it/20983-2/" target="_blank">https://web-en.unipv.it/20983-2/</a></div><div><br></div><div><a href="https://www.youtube.com/watch?v=0n-rRMMbFNk" target="_blank">https://www.youtube.com/watch?v=0n-rRMMbFNk</a></div><div> </div><div>How to reach my office: DICAR, first entrance at the right of the "via Ferrata 3" gate, first floor, after the stairs, turn right: I am on the left before the Dept. admin area.</div><br></div></div></div></div></div></div><div style="line-break:after-white-space"><div dir="ltr"><div class="gmail_quote"><div style="line-break:after-white-space"><div><div></div></div></div></div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br></div></div></div></div></div></div>
