Bluff body 뜻
WebThe bluff body flow is that there is a very strong interaction between the inviscid and viscous regions. A body is said to be streamlined \textbf{streamlined} streamlined if a conscious effort is made to align its shape with the anticipated streamlines in the flow. Streamlined bodies such as race cars and airplanes appear to be contoured and sleek. WebBluff-body burners have been used with a range of bluff-body diameters, D b and fuel jet diameters, D j. Stability characteristics of these flames are given in terms of the fuel jet velocity, u j and the coflow velocity, u e; and have been published elsewhere [1,10]. The length of the recirculation zone is about one bluff body diameter.
