Experimental and Theoretical Investigations Concerning the Influence of Stagnation Region on Karman Vortex Shedding

The paper contains an attempted explanation of the stagnation region's role in vortex shedding. The stagnation region appears in the closest neighborhood downstream of the bluff body, and is a factor which considerably influences vortex shedding. Former investigations of these phenomena in the vortex meter entitle the author to summarize yielded results and to formulate the overall conclusions concerning the mentioned problem. Analysis of the results gained due to various method applications is presented in the paper. The role of the stagnation region during the vortex shedding process is discussed.
