Günter Brenn investigates the behaviour of gas bubbles and liquid drops at the Institute of Fluid Mechanics and Heat Transfer at TU Graz. Lunghammer - TU Graz By Susanne Filzwieser - Why do large gas bubbles in viscoelastic liquids (such as polymer and protein solutions) rise so much faster than expected? An open question with great relevance for industrial production processes. Researchers at TU Graz and TU Darmstadt have now found an explanation. Further at the end of the text - Günter Brenn heads the Institute of Fluid Mechanics and Heat Transfer. Lunghammer - TU Graz - It is a puzzle long known among experts and very relevant in many industrial production processes: a jump discontinuity in the rise velocity of gas bubbles in so-called viscoelastic fluids. Viscoelastic fluids are substances that combine characteristics of liquid and elastic substances. Many hair shampoos are an example of this.
