Global and Koopman modes analysis of sound generation in mixing layers [PDF]

open access: yes, 2013
It is now well established that linear and nonlinear instability waves play a significant role in the noise generation process for a wide variety of shear flows such as jets or mixing layers.

Linear stability analysis of blood flow in small vessels

open access: yesApplications in Engineering Science, 2020
We investigate the linear stability of unidirectional Poiseuille flow of blood modeling the fluid as a spatially inhomogeneous fluid in which viscosity depends on the red blood cell concentration (RBCs).

Multi-Angle Liquid Flow Measurement Using Ultrasonic Linear Array Transducer

open access: yesSensors, 2020
Most ultrasonic flowmeters utilize several wedge sensors for transmission and reception. Thus, the location and alignment of the sensors are critical factors that determine the performance of the ultrasonic flowmeter.

Non-linear laminar flow into eccentrically placed well

open access: yesAnnals of Geophysics, 1975
In steady s t a t e condition, non-linear laminar flow of fluid into an eccentrically placed well is considered. Its influence on tlic discharge and t h e dependence on r e l a t e d physical q u a n t i t i e s is investigated. I t is ...

Reversal of the lift force on an oblate bubble in a weakly viscous linear shear flow [PDF]

open access: yes, 2009
We compute the flow about an oblate spheroidal bubble of prescribed shape set fixed in a viscous linear shear flow in the range of moderate to high Reynolds numbers.

Linear and non-linear flow mode in Pb–Pb collisions at sNN=2.76 TeV

open access: yesPhysics Letters B, 2017
The second and the third order anisotropic flow, V2 and V3, are mostly determined by the corresponding initial spatial anisotropy coefficients, ε2 and ε3, in the initial density distribution.

Bench scale laboratory tests to analyze non-linear flow in fractured media [PDF]

open access: yesHydrology and Earth System Sciences, 2012
The knowledge of flow phenomena in fractured rocks is very important for groundwater resources management in hydrogeological engineering. <br><br> A critical emerging issue for fractured aquifers is the validity of the Darcian-type "local ...

Linear Stability of a Steady Convective Flow between Permeable Cylinders

open access: yesFluids, 2021
Linear stability analysis of a steady convective flow in a tall vertical annulus caused by nonlinear heat sources is conducted in the paper. Heat sources are generated as a result of a chemical reaction.

Linear Flows on $\kappa $-Solenoids

open access: yesTopology and its Applications, 1999
Linear flows on inverse limits of tori are defined and it is shown that two linear flows on an inverse limit of tori are equivalent if and only if there is an automorphism of the inverse limit generating the equivalence.

Turbulent structures, integral length scale and turbulent kinetic energy (TKE) dissipation rate in compound channel flow

open access: yes, 2017
In the present study, high data rate measurements were obtained for the streamwise and vertical velocity components using 2D Laser Doppler Velocimeter. The turbulent field in a straight compound-channel flow was characterized for three different uniform ...
