Description:
In this paper we consider the possibility of generating homogeneous flows with a nearly constant strain rate. This is achieved by stretching an almost cylindrical liquid bridge under microgravity. One key issue is the adjustability of the disk diameters, necessary for maintaining ideal boundary conditions. We first study the stretching of two different fluids by both numerical and experimental means. The numerical results are compared with the experimental data and very good agreement is found. The numerical method is then used to study the behaviour of liquid bridges for quite a large range of the flow parameters (capillary number Ca and Weber number We) in order to detect those regimes with most suitable flow conditions. © 2004 Cambridge University Press.
