| Abstract: | By using the 2 dimension LDV system,the experiment on the characteristics of the flow field at the orifice plate was carried out.How the shape of inner edge of orifice plate affects the flow field was thoroughly studied.A complete model in circular pipe and another one in rectangular pipe which shows the section of inner edge were used.By comparison and analysis,the relation between the development of the seperate separated flow behind orifice and the shape of inner edge was acquired.Consequently,the mechanism concerning the effect of the shape of inner edge to the energy dissipation coefficient was revealed. |
