To generalize simple bead-linker model of swimmers to higher dimensions and to demonstrate the chemotaxis ability of such swimmers, here we introduce a low-Reynolds predator, using a two-dimensional triangular bead-spring model. Two-state linkers as mechanochemical enzymes expand as a result of interaction with particular activator substances in the ...

Newton’s second law of motion stipulates that the rate of change of momentum of a fluid parcel must be balanced by the body force exerted over the parcel volume and by the surface force exerted on the parcel boundary. Under certain conditions, the rate of change of momentum of the parcel is small compared to the body and surface force, and can be ...

Having discussed viscous flow at low Reynolds numbers in Chapter 9, now we turn our attention to the diametrically opposite limit of inertia-dominated flow at high Reynolds numbers. Inspecting the changes in the structure of a flow with increasing Reynolds number, we encounter a rich phenomenology and a variety of transition protocols.

Intermittency and Reynolds number
Physics of Fluids, 1998Hot wire measurements of longitudinal and transverse increments are performed in three different types of flows on a large range of Reynolds numbers (100≲Rλ≲3000). An improved technique based on cumulant expansion of velocity structure functions is used to estimate the spreading of the pdfs and to study their scaling properties in the inertial range ...

Reynolds-Zahl Re (Reynolds number Re)
2000Es handelt sich urn eine dimensionslose Kennzahl im Sinne der Dimensionsanalysis. Als solche tritt sie formal bei der Entdimensionierung der Impulsgleichung (Kraftegleichgewicht an einem Fluidelement) auf. Wegen der Kopplung der Impulsgleichung mit der Thermischen Energiegleichung uber die sog.

Transonic low-Reynolds number airfoils
Journal of Aircraft, 1991Airfoils operating in the unexplored high-Mach—low-Reynolds number regime are computationally investigated. The motivations are 1) quantificatio n of achievable airfoil performance levels; 2) quantificatio n of parameter sensitivities which impact vehicle sizing; 3) identification of possible shortcomings in the computational methods employed; and 4 ...
