Effects of the finite particle size in turbulent wall-bounded flows of dense suspensions
, 2018 We use interface-resolved simulations to study finite-size effects in turbulent channel flow of neutrally-buoyant spheres. Two cases with particle sizes differing by a factor of 2, at the same solid volume fraction of 20% and bulk Reynolds number are ...

Effects of elastic anisotropy on the small fatigue crack deflection behavior of α-brass
Journal of Materials Research and TechnologyIn this study, we conducted tests using an electrodynamic plane bending fatigue testing machine to closely observe the propagation behavior of a small fatigue crack generated on the surface of α-brass. We also employed the electron backscatter deflection

Effect of Patterned Slip on Micro and Nanofluidic Flows
, 2005 We consider the flow of a Newtonian fluid in a nano or microchannel with walls that have patterned variations in slip length. We formulate a set of equations to describe the effects on an incompressible Newtonian flow of small variations in slip, and ...

A Novel Slip Correction Factor For Spherical Aerosol Particles
, 2008 A 3D simulation study for an incompressible slip flow around a spherical aerosol particle was performed. The full Navier-Stokes equations were solved and the velocity jump at the gas-particle interface was treated numerically by imposition of the slip boundary condition.

Equations of the blade loading and the slip factor of a centrifugal impeller.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1986 A simple equation for expressing the blade loading of an impeller and a modified Wiesner's slip formula taking account of this blade loading are presented. The performance of four different types of impeller with the same exit diameter, blade exit width, and number of blades was tested. Further, the slip factor of all impellers were measured by using a

Slip Factor Prediction for Impellers with Straight, Back-swept Blades [PDF]
R&D Journal, 2019 Slip factor accounts for the deviation of the flow angle from the trailing edge blade angle at the exit of radial impellers. Accurate values are required to predict impeller torque and energy input. The slip factor prediction method for back-swept radial bladed impellers is based on the so-called single relative eddy (SRE) method, which is an ...

Computational analysis of non-Newtonian boundary layer flow of Nanofluid past a vertical plate with partial slip [PDF]
, 2017 In the present study, the heat, momentum and mass (species) transfer in external boundary layer flow of Casson nanofluid over a vertical plate surface with multiple slip effect is studied theoretically.

Transforming mesoscale granular plasticity through particle shape
, 2018 When an amorphous material is strained beyond the point of yielding it enters a state of continual reconfiguration via dissipative, avalanche-like slip events that relieve built-up local stress.
