- A first-ever proof of existence of skin-friction critical points in turbulent flows was achieved by using the innovative micropillar sensor technology. This experiment inspired many other research proposals, e.g. in fundamental research of flow separation in flow with adverse pressure gradients, in the field of turbulent heat transfer and the generation of hot spots at these singularities (e.g in pulsating channel flow), as well as in natural convection flows at high Re- and Rayleigh numbers. This research has led to two invited Keynote Speeches at international Conferences
