Description of Work: 


The formation of liquid drops using micro-channels has been put forward by many researchers. The advantage of using micro-channels is that the shearing of a liquid by a second liquid can be used to control the size and type of drops that are formed. Micro-devices with simple or complex channels can be configured and produced that will allow a sequence of steps to be applied to the drop formation and the drops formed. This gives rise to the possibility of creating micro-factories that can take the raw material (liquid) and produce a product that has characteristics for a particular application (drops with coating and trace chemicals present). This project will look at the formation of droplets that encapsulate multiple droplets of other liquids and model the drop formation process.

Description of Work:

  • Carry out a survey of the current status with encapsulated drop formation using micro-devices.
  • Design and manufacture micro-devices for encapsulated drop formation using the micro-milling facility available.
  • Study the characteristics of encapsulated drop formation using Newtonian and non-Newtonian fluids.
  • Develop a model to predict the drop encapsulation processes.
