Abstarct: Emulsions, foams, aerosols and other dispersions are examples of multiphase fluids. These materials have applications in various fields such as therapeutic, nutritional, petroleum and so on. In many of these applications, the production of these materials is uncontrolled while there are many methods for Size control and volume distribution are available in the emulsion field. Latest things in order Emulsification is accompanied by methods for precise control of droplet size on a micrometer scale , Which enables precise control of chemical compounds and heat transfer environments as well.A drop can be used individually as an isolated chemical content To take. One of the great advantages of microfluidic devices is the ability to control droplet formation They have very large scales. Hence the micro fluid droplets using the channels and tubes that they have Are also micrometer-scale, obtained to form a drop of a continuous aqueous phase Energy must be transferred to the droplet surface to convert some of the energy to surface energy. It doesn't make me energy Is to come from a hydrodynamic pressure induced by a flow that has no other external input and with It is known as passive drop production but if an external energy is locally oriented Entering drop production is called active drop production. Usually required to create Dubai Syringe pumps are used with a controllable discharge however pressure control units are also used for Flow drift is used. The microfluidic channel provides a boundary for the micro current The geometry of these boundaries can influence the droplet formation. In recent years development MEMS technology-baxsed microfluidic systems have attracted the attention of scientists and artisans has done. Recent advances have been baxsed more on conventional semiconductors and more on technologies The field of integrated circuits has improved. Using these materials and technologies for systems Not only is the Vicky Maker expensive but it also has many limitations. At work ahead PDMS polymer was used to make the channel. What we needed in our research was just to find the diameter of the droplets Was. To do this, the primary image is taken from a high-speed camera attached to a microscope, cropping the imageIt is done so that only one full drop is placed in the resulting image and its height is equal to the width Be the channel. The image becomes binary, yet using the method of finding the edges, the edges of the drop Find and consider an appropriate threshold value Extra image components are eliminated and finally the diameter The pixel is found and converted to a diameter in proportion to micrometers. Finally with communication The camera, the pumps, and the PC turn to the design of a control Floodgram. To control this The system and the desired size were used to control the PID. The behavior of the drops drastically It is non-linear that this is a major challenge in controlling drop production. Nonlinearity of behavior Drops can also be affected by pump vibrations. In this article we tried a method to control Provide the optimum droplet production process. But we will see that the highly nonlinear behavior of these drops It makes it very difficult. However we were able to do this with a simple but very effective PID controller Of course with the use of more advanced hardware, the pump with less vibration can certainly The results were more appropriate. However, the behavior of biphasic microfluidics is inherently nonlinear and presents a model Efficient math is very difficult to design for a droplet size control model It has very powerful processors and expensive results.
