Abstract: For very low relaxation time (i.e., lesser than a microsecond), viscoelastic fluid experimental determination is difficult, if not impossible. In this work, the relaxation time measurement of a weakly elastic polymer ...

Abstract: In this work, the influence of nozzle shape on microfluidic ink jet breakup is investigated. First, an industrial ink used in continuous inkjet (CIJ) printing devices is selected. Ink rheological properties are measured ...
