Microfluidic Dpiv Technology And Its Real-time Analysis Of The Oil Pollution In The Study

On the basis of digital image processing technology, we made a research of measurement technology of micro flow field, brought forward a new velocity calculation method of whole flow field, and analysed its application in oil contamination on time analysis ststem. The main research work is introduced as followings:1. Microfluid flow: Sample pool is a very important part of oil contamination on time analysis ststem. As a result of the micron dimension of sample pool, the liquid in it can be viewed as microfluid. At the beginning of the paper, we analysed the flow characteristic of microfluid, the dimension partition of microfluid, the major influence factors, and the research method.2. Digital Particle Image Velocity: Particle Image Velocity(PIV) technology, is turned into Digital Particle Image Velocity(DPIV) technology in recent years. Compared to PIV technology, DPIV technology has the advantages of faster processing and smaller errors. So we made a detailed research of DPIV technology, which mostly includes the principle of velocity mesurement of DPIV, digital image processing, the correction of velocity vectors, the construction of flow field and so on.3. Oil contamination on time analysis ststem: The major purpose of our research of microfluid DPIV technology is expected to provide the reasons for the development and perfection of oil contamination on time analysis ststem. Finally, we analysed the application of microfluid DPIV technology in oil contamination on time analysis ststem, and achieved the expectant results.
