Abstract:

Ferrofluids (FFs) are colloid liquids susceptible to magnetic field. Although they represent a novelty in Hydraulics, they have been widely used in engineering sciences since the eighties, with different industrial and biomedical applications. Here, a collection of experiences carried out in hydraulic laboratories is presented. Indeed, FFs have been exploited to measure key hydraulic quantities (e.g. wall friction). Moreover, their interaction with flow have been investigated with original techniques (optical methods, microfluidics) observing the rise of novel phenomena (e.g. lubrication).
