Abstract
A curved liquid jet is widely used in various practical applications, such as the prilling process for generating small spherical pellets (fertilizer) and inkjet printing. A deep understanding of the mechanisms of the break-up of liquid jets and the associated flow dynamics are heavily dependent upon the nature of the fluid. In this paper, we model the viscoelastic liquid jet by using the Giesekus model. In addition, the governing equations have been reduced to 1-D by using an asymptotic approach. Then, we determine the trajectory of viscoelastic liquid curved jets. Furthermore, the nonlinear evolution equations for the jet radius and the axial velocity are solved numerically using finite differences scheme based on the Lax-Wendroff method.
