A slender jet model is used to describe the instability of a curved liquid jet falling under gravity. The fluid is modelled as an inelastic non-Newtonian fluid obeying the Carreau model. A linear instability analysis is performed to examine the behaviour of the most unstable wavenumber and growth rate of instabilities.
