Study of droplet-wire fragmentation related to gas liquid separators

In this thesis, droplet-wire impaction and the following fragmentation of the droplet related to gas-liquid separators has been studied. First, an experimental setup has been developed, then a model was made in Matlab in order to be able to read data from the experiments. The main focuses of this thesis are: • Experimental study of droplet behavior on wire at the laboratory • Obtaining theoretical information of the subject • Developing a model in Matlab to obtain data from images taken at the laboratory The experiments have been done with water droplets at atmospheric pressure and at a room temperature of ~20oC. Results from 43 events have been made available in the appendices, all of them which outputs are from Matlab. Many setups with different settings have been tested to make the laboratory as good and as easy as possible. Different velocities together with ratio between wire and droplet diameter are the main sources of different dispersion in the fragmentation. The reader of this thesis should easily be able to setup the equipment by following the description, given that all the equipment is available at hand. To capture the fragmentation, a high speed camera together with a trigger mechanism and necessary equipment to control units has been used. The images acquired by experiments, are input to the scripts made in Matlab to see the effect of different velocities and droplet size. It’s been proven that by increasing the income velocity of the droplet, the number of small fragmented droplets increase. The scripts that are made will need more work to be able to figure out size and number of small droplets after impaction between droplet and wire.
