The immersion method of applying a coating to an object presents a central challenge: predicting the thickness of the layer that will cover the object. This question raises important financial issues for manufacturers. A team from the CBI laboratory at ESPCI Paris and from the College de France has developed an experimentally verified theoretical framework to predict the coating thickness in the case of yield-stress fluids. The researchers just reported their findings in the journal Physical Review Letters.
