Among the literature on acoustics the book of Pierce [] is an excellent introduction available for a low price from the Acoustical Society of America. In the preparation of the lecture notes we consulted various books which cover different aspects of the problem [15, 17, 19, 39, 50, 72, 89, 95, , , , , , , , , ]. The minimum Reynolds number on the stability curve on flat plate is. U cs 1 1 s = = ∞ ν δ Reδ, (6) where δ 1 is the displacement thickness. At lower Reynolds numbers all disturbances are dissipated but turbulence does not set in at that point. From this critical stability Reynolds number onwards the disturbance can grow but. A viscous silicon oil has been used in a Venturi geometry to explore the flow for Reynolds numbers ranging from R e = to R e = Special care has been taken to extract the maximum amount of dissolved air. At the lowest Reynolds numbers the cavities are steady and grow regularly with decreasing ambient pressure. Stability bounds for explicit fractional-step schemes for the Navier–Stokes equations at high Reynolds number Computers & Fluids, Vol. 38, No. 6 Noise Generation Analysis of a Cylindrical Cavity by LES and Global Instability.

The Reynolds number (Re) helps predict flow patterns in different fluid flow low Reynolds numbers, flows tend to be dominated by laminar (sheet-like) flow, while at high Reynolds numbers flows tend to be turbulence results from differences in the fluid's speed and direction, which may sometimes intersect or even move counter to the overall direction of the flow. regurgitant jet, hugging the walls of the left atrium (LA) known as the Coanda e ect. certain cases the regurgitant jet hugs the wall of the heart's atrium as shown in Figure 1(c). These eccentric, wall-hugging, non-symmetric regurgitant jets have been observed at low Reynolds numbers [5, 6] and are said to undergo theCoandae ect[7,8]. Three-dimensional jet flows at high Reynolds (Re) numbers, namely over a million, have a significant importance in hydraulic e their importance, most of the previous investigations have been mainly focused only on jet flows with orders of magnitude lower Re numbers.

For larger Reynolds numbers, extensive experimental determinations of the drag coefficient have been made (Schlichting, , or Fuchs, , p. 32). roborated through several studies, including the atomization of a liquid diesel jet at moderately low Reynolds number, Re = In a related study, Desjardins & Pitsch conducted detailed numerical simulations of primary atomization for several values of Reynolds and Weber numbers ( We present the first integrative computational fluid dynamics (CFD) study of near- and far-field aerodynamics in insect hovering flight using a biology-inspired, dynamic flight simulator. This simulator, which has been built to encompass multiple mechanisms and principles related to insect flight, is capable of `flying' an insect on the basis of realistic wing–body morphologies and kinematics.
