Direct numerical simulations (DNS) are used to examine the pressure fluctuations generated by a spatially-developed Mach 5.86 turbulent boundary layer. The unsteady pressure field is analyzed at multiple wall-normal locations, including tho...

The effect of permeability heterogeneities and viscosity variations on miscible displacement processes in porous media is examined using high-resolution numerical simulations and reduced theoretical modelling. The planar injection of one fl...

This paper is concerned with the high Reynolds number flow over a spanwise-periodic array of roughness elements with interelement spacing of the order of the local boundary-layer thickness. While earlier work by Goldstein et al. (J. Fluid M...
Film thickness distribution in gravity-driven pancake-shaped droplets rising in a Hele-Shaw cell [0.03%]
在Hele-Shaw细胞中上升的重力驱动的煎饼形液滴中的薄膜厚度分布
Isha Shukla,Nicolas Kofman,Gioele Balestra et al.
Isha Shukla et al.
We study here experimentally, numerically and using a lubrication approach, the shape, velocity and lubrication film thickness distribution of a droplet rising in a vertical Hele-Shaw cell. The droplet is surrounded by a stationary immiscib...
Exact regularized point particle (ERPP) method for particle-laden wall-bounded flows in the two-way coupling regime [0.03%]
双向耦合区壁面约束携带颗粒流的精确正则点粒子（ERPP）方法

F Battista et al.
The Exact Regularized Point Particle (ERPP) method is extended to treat the interphase momentum coupling between particles and fluid in the presence of walls by accounting for the vorticity generation due to the particles close to solid bou...

Electro- and diffusio- phoresis of particles correspond respectively to the transport of particles under electric field and solute concentration gradients. Such interfacial transport phenomena take their origin in a diffuse layer close to t...
Effects of surfactant on propagation and rupture of a liquid plug in a tube [0.03%]
界面活性剂对管内液柱传播及破裂的影响研究

M Muradoglu et al.
Surfactant-laden liquid plug propagation and rupture occurring in lower lung airways are studied computationally using a front-tracking method. The plug is driven by an applied constant pressure in a rigid axisymmetric tube whose inner surf...

A family of cases each containing a small separation bubble is treated by direct numerical simulation (DNS), varying two parameters: the severity of the pressure gradients, generated by suction and blowing across the opposite boundary, and ...
A theory for the slip and drag of superhydrophobic surfaces with surfactant [0.03%]

Julien R Landel et al.
Superhydrophobic surfaces (SHSs) have the potential to reduce drag at solid boundaries. However, multiple independent studies have recently shown that small amounts of surfactant, naturally present in the environment, can induce Marangoni f...
