| Airflow distribution simulation test is a available method for the airflow uniform distribution realization in electric precipitator. Using the test result to direct design of industry electric precipitator , whatever on economy, on time, and on work condition, it has great superiority over direct test and adjustment. Therefore, the method has been widely utilized.Because of the complexity of electric precipitator interior flow field, the problem can not be solved in theory. The precision and the range of use of kinds of equation are not satisfactory, the computational fluid dynamic can not easily attain better solution while the flow boundary condition is complicated. In virtue of similarity theory, utilizing the model experiment to predict airflow of electric precipitator can not depend on empirical formula, it is a most reliable method. Presently, the surveying instrument can just survey some points in the flow field. It is difficult to provide whole flow field information, nevertheless, the information are imperative for airflow of electric precipitator research.The appearance of PIV makes that people can survey the whole flow field velocity profile for the first time, moreover, the survey has high precision. The dissertation successfully utilizes the PIV to airflow model experiment of electric precipitator, attain several significant data and obtain satisfactory result.The main work and creative point of the dissertation:1. Make use of similarity theory, set up experimental platform of performance simulation of electric precipitator,and do the air distribution experiment of electric precipitator by the clear water.2. Introduces the PIV operation guide by specific experiment.Measures airflow distribution of electric precipitator under three kinds of work condition by the... |
