Galindo-Rosales\, Transport Phenomena Research Center\, CE FT | December 5\, 2019 – 17h00 | FEUP Sala B020\n\nSmart fluids are comp lex fluids that exhibit a change in their rheological properties upon the application of an external stimulus\, which can be light\, heat\, electric field or magnetic field. Among them\, electrorheological fluids and magne torheological fluids are at the forefront of advance applications\, such a s soft robotics\, fluidic valves\, clutches\, cleaning oil spills\, etc. T he success of these applications will rely fundamentally on the precise kn owledge of the rheological properties of the smart fluids. However\, comme rcially available rheometers are limited to provide the rheological behavi or of these fluids under shear flow\, which means information about just o ne-fourth of the rheological map of behaviors. We have developed some devi ces in the Transport Phenomena Research Center (CEFT)\, under the framewor k of the RheoOptimized2Dinks and Ferro-Clean projects\, that allow providi ng complementary rheological information about their behavior under extens ional flow. Having both characterizations\, i.e. under shear and extension al flows\, is the key for selecting the right constitutive equation and\, therefore\, being able to simulate the behavior of these fluids under real conditions and optimize the\nperformance of the final product.\n\nThis se minar will describe the basic principles of rheology and complex fluids\, focusing in particular on relevant properties of smart fluids and showing some of the sci-fi applications that are coming out in the last years. We will see the different techniques available in the market for performing r heological characterization of smart fluids and we will highlight the empt y gaps. Finally\, we will talk about the solutions developed at CEFT and s ome of the latest results will be shown.\n\n\n\nF.J. Galindo-Rosales is a researcher with more than 10 years of research experience in rheology and\ nmicrofluidics. He obtained his Ph.D. degree in Fluid Mechanics by the Uni versity of Málaga (Spain) in 2008 and worked as a Post-Doctoral researche r in the Soft Matter\, Rheology and Technology group of the KU Leuven (Bel gium\, 2008-10) before arriving at CEFT/FEUP back in 2010. Since then\, he has secured more than 830 k€ through 5 research projects with FCT and i nternational companies\, such as Ultimaker B.V.\; published 30 articles (S copus h-index 15)\, 3 edited books and 5 patents. He is the organizer of t he Summer School on Complex Fluids in Microfluidics since 2017 and co-foun der of Rheinforce Optimal Performance Lda\, an UPorto Spin-Off company (ww w.rheinforce.com).\n\n\n\n \;\n\n[Host: Joaquim L Faria\, Associate La boratory\, LSRE-LCM]\nImage credits: Sara S Pereira<\;/em ATTACH;FMTTYPE=image/jpeg:https://deq.fe.up.pt/wp-content/uploads/2019/12/ 1205_1700_FJGalindoRosales_1920_1S-SEMI-e1576263716656.jpg END:VEVENT END:VCALENDAR
