Experimental investigations of Strouhal number for flows past dual triangulate bluff bodies

Confined flow and heat transfer across a triangular cylinder in a channel

“…On the other hand, sufficient information is available in the literature on the flow around a triangular cylinder in the turbulent flow regime (El-Sherbiny [6]; Nakagawa [7]; Tatsuno et al [8]; Wahed et al [9]; Sharif and Gu [10]; Camarri et al [11]; Chattopadhyay [12]; Peng et al [13] and Srigrarom and Koh [14]). …”

A new approach to detection of vortices using ultrasound

“…Strouhal number, for different shapes of bluff body has values ranging from 0.18 to 0.28 [14,15,32].…”

“…Strouhal number is constant for a wide range of Reynolds number (10 4 rR e r 5 Â 10 5 ), and depends on the shape of the bluff body [9,15,16].…”

Asymmetric Bounded Neural Control for an Uncertain Robot by State Feedback and Output Feedback

“…In most situations, velocity signals are exceedingly difficult or even impossible to measure. Then researchers try to design the state observer to estimate the immeasurable states, and many research results have been carried out [55], [56]. In [57], a state observer is designed to estimate the immeasurable states such that an adaptive neural output feedback control is developed for large-scale stochastic nonlinear systems.…”
