Abstract While the wake of a circular cylinder and, to lesser extent, normal flat plate have been studied in considerable detail, wakes elliptic cylinders not received similar attention. However, from first two bodies considerably different characteristics, terms three-dimensional transition modes, and near- far-wake structure. This paper focuses on cylinders, which span these disparate cases. The Strouhal number drag coefficient variations with Reynolds are documented for two-dimensional...
A liquid marble micro‐bioreactor is prepared by placing a drop of murine embryonic stem cell (ESC) (Oct4B2‐ESC) suspension onto polytetrafluoroethylene (PTFE) particle bed. The Oct4B2‐ESC aggregates to form embryoid bodies (EBs) with relatively uniform size and shape in within 3 d. For the first time, feasibility differentiating ESC into cardiac lineages marbles being investigated. Without addition growth factors, suspended EBs from express various precardiac mesoderm markers including...
Flow transitions are an important fluid-dynamic phenomena for many reasons, including the direct effect on aerodynamic forces acting body.

Two-dimensional flow past a cylinder close to free surface at Reynolds number of 180 is numerically investigated. The wake behaviour for Froude numbers between 0.0 and 0.7 gap ratios 0.1 5.0 examined. For low numbers, where the deformation minimal, simulations reveal that this problem shares many features in common with no-slip wall. This suggests largely governed by geometrical constraints low-Froude-number limit.At excess 0.3–0.4, becomes substantial. can be traced increases local unity or...
The low-Reynolds-number wake dynamics and stability of the flow past toroids placed normal to direction are studied numerically. This bluff body has attractive feature behaving like sphere at small aspect ratios, locally straight circular cylinder large ratios. Importantly, geometry ring is described by a single parameter, ratio (, initial asymmetric transition structurally analogous mode A for cylinder, with discontinuity present in Strouhal–Reynolds-number profile. numerical study reveals...
This paper reports on an extensive parameter space study of two-dimensional simulations a circular cylinder forced to oscillate transverse the free-stream. In particular, extent primary synchronization region, and wake modes energy transfer between body fluid are analyzed in some detail. The frequency range region is observed be dependent Reynolds number, as obtained. Energy primarily at low amplitudes oscillation, but amplitude high oscillation. However, oscillation corresponding zero found...
A Floquet stability analysis of the transition to three-dimensionality in wake a cylinder forced oscillate transversely free stream has been undertaken. The effect varying oscillation amplitude is determined for frequency close natural shedding frequency. three-dimensional modes that arise are identified, and on their structure growth rate quantified. It shown when two-dimensional 2 S configuration (which similar Kármán vortex street), nature symmetry fixed cylinder. These known as A, B QP...
We present detailed quantitative measurement analyses for flow in a spinner flask with spinning rates between 20 to 45 RPM, utilizing the optical velocimetry technique of Particle Image Velocimetry (PIV). A partial section impeller was immersed working fluid reduce shear forces induced on cells cultured microcarriers. Higher rotational speeds improved mixing effect medium at expense higher environment. It found that mouse pluripotent stem (iPS) achieved optimum number over 7 days 25 RPM...

Abstract The wake of a rotating circular cylinder in free stream is investigated for Reynolds numbers $\mathit{Re}\leqslant 400$ and non-dimensional rotation rates $\alpha \leqslant 2. 5$ . Two aspects are considered. first the transition from steady flow to unsteady characterized by periodic vortex shedding. two-dimensional computations show that onset delayed higher as rate increased, shedding suppressed \geqslant 1$ all parameter space investigated. second aspect three-dimensional using...
While it has been known that an afterbody (i.e. the structural part of a bluff body downstream flow separation points) plays important role affecting wake characteristics and even may change nature flow-induced vibration (FIV) structure, question whether is essential for occurrence one particular common form FIV, namely vortex-induced (VIV), still remains. This motivated present study to experimentally investigate FIV elastically mounted forward- or backward-facing D-section (closed...
Despite little supporting evidence, there appears to be an implicit assumption that the wakes of two-dimensional bluff bodies undergo transition three-dimensional flow and eventually turbulence, through same sequence transitions as observed for a circular cylinder wake. Previous studies square wake support this assumption. In paper, is examined elongated with aerodynamic leading edge trailing edge. The instability modes are determined function aspect ratio ( $\hbox{\it AR}\,{=}\,$ length...
The three-dimensionality of the velocity field in wake a circular cylinder has excited considerable interest and debate over past decade. Presented here are experimental results that characterize underlying vorticity such wakes. Using particle image velocimetry (PIV), instantaneous fields were measured from these longitudinal vortices lying region between Kármán was found. Near saddle point, induced by stretching vortices, found to be greater than themselves. Their circulation order 10%...
