Acoustic streaming underpins an exciting range of fluid manipulation phenomena of rapidly growing significance in microfluidics, where the streaming often assumes the form of a steady, laminar jet emanating from the device surface, driven by the attenuation of acoustic energy within the beam of sound propagating through the liquid. The frequencies used to drive such phenomena are often chosen a...
This study investigates the Hagen–Poiseuille pipe flow of viscoplastic fluids, focusing on analytical predictions concrete pumping using shear-stress-dependent parabolic model, extending studies to a nonlinear rheological model with easily accessible experimental parameters. Research novelty and highlights encompass solving steady laminar for fluids described by presenting detailed results two-...
This paper describes the use of laminar flow of liquids in capillary systems to pattern the cell culture substrate, to perform patterned cell deposition, and to pattern the cell culture media. We demonstrate the patterning of the cell culture substrate with different proteins, the patterning of different types of cells adjacent to each other, the patterned delivery of chemicals to adhered cells...
We reveal the effects of sweep on wake dynamics around NACA 0015 wings at high angles attack using direct numerical simulations and resolvent analysis. The influence is considered for from $0^\circ$ to $45^\circ$ $16^\circ$ $30^\circ$ a spanwise periodic wing chord-based Reynolds number $400$ Mach $0.1$ . Wing affects dynamics, especially in terms stability fluctuations with implications develo...
Bedload transport generally depends on the bed shear stress and Reynolds number. Many studies conducted for the condition of turbulent flows have revealed the dependence of the transport rate on the bed shear stress, while knowledge of the Reynolds number effect on the transport rate is very limited. As an extreme case to reflect the viscous effect on sediment transport, sediment transport in l...
The paper presents a new two-dimensional computational approach and results for laminar/laminar internal condensing flows. Accurate numerical solutions of the full governing equations are presented for steady and unsteady film condensation flows on a sidewall inside a vertical channel. It is found that exit conditions and noise sensitivity are important. Even for stable steady solutions obtaine...
