Flowmatters is a consultancy company originating from the Delft University of Technology (TU Delft), with the expertise on the interface of Fluid Dynamics and Surface Tribology. An exceptional testing facility to measure frictional drag has been developed based on scientific research and fundamental fluid dynamics knowledge.The test facility is unique due to the high accuracy and reproducibility, at which the turbulent flow is similar to the practical conditions. The data contribute to an understanding of fluid-surface interaction and may help further improvements during the development process.Flowmatters is specialized in frictional measurements of:- Drag Reducing Surfaces- Coatings, Paints & Foils- Swimming Textiles- Drag Agents (e.g. polymers, surfactants, bubbles)
