The Suvis GmbH is also active in fundamental research. For that, it closely cooperates with the chair of fluid mechanics of the Chemnitz University of Technology, faculty of mechanical engineering. Subject of research is the so-called Rayleigh-Benàrd convection, a flow configuration which results when a fluid layer is cooled from above and heated from below (unstable stratification). For that, joint experimental and numerical investigations have been performed, which already lead to two reviewed journal publications [1,2], see below. The investigated convective flow form plays a fundamental role in various technical applications like the heat transfer in solar collectors or double glazed windows, for example.
