3) streamline body 流线型物体 4) bluff body; bluff 非流线体 5) non-streamline submerged body 非流线型水下航行体 1. Taking anon-streamline submerged bodyas a model, its drags under the natural condition and artificial ventilated condition are numerically simulated using mixed homogeneous flow theor...
Tailoring the gain and phase of the flame transfer function through targeted convective-acoustic interference By placing a set of small diameter cylinders, a streamlined body, or a swirler upstream of the bluff body and varying the distance from the dump plane... E Sy,HT Nygrd,NA Worth,......
The experiment conducts wind tunnel tests on 3 different bodies, a plate, a sphere and a streamlined body. Drag under different Reynolds number are recorded and studied. We also focus on finding the critical point between laminar and turbulent.Discussion 1.Discuss the observations and measurements ...
An experimental investigation of the effect of the boundary layer on cavitation inception for a smooth streamlined body of revolution is described. The influence of air diffusion upon the observed results is also discussed, In addition, this study has shown that tensions exist in the flow of ordin...
The solution is illustrated by the example of the uniform flow past two parallel plates, one of which represents the bluff body and one of which represents the barrier.doi:10.1007/BF00916489I. A. BelovKluwer Academic Publishers-Plenum PublishersJournal of Applied Mechanics & Technical Physics...
According to this interpretation, the Strouhal number (also for a body at rest) is constant for a wide range of side ratios and equal to about 0.6 (if normalized with the cross-section width). The impinging shear-layer instability is particularly pronounced for an H-shaped geometry and the ...
Waves generated by a moving submerged moving body were analyzed in a two-layer density fluid. The experiments were performed in a two-dimensional towing tank and compared to the numerical results from a two-dimensional, fully nonlinear numerical towing tank (NTT) based on potential flow. The exp...
A streamlined, pod-shaped body which is symmetrical about an axis parallel to the direction of travel achieves a very low coefficient of drag and maximizes laminar flow to further reduce drag. The cycle wheels are contained within two streamlined fairings which extend from the streamlined cycle ...
These small components prevent generation of leading-edge vortexes caused by body motion. This can also be achieved by optimizing aerodynamic configurations (Larsen et al., 2000; Kwok et al., 2012; Fujino and Siringoringo, 2013). For long-span bridges, attachments to bridge girders, such as...
