Invariant Solution underlying Oblique Stripe Patterns in Plane Couette Flow
, 2018 When subcritical shear flows transition to turbulence, laminar and turbulent flow often coexists in space, giving rise to turbulent-laminar patterns. Most prominent are regular stripe patterns with large-scale periodicity and oblique orientation. Oblique

High‐Rate Deposition and Characterization Study of CoZrO Films for On‐Chip Power Applications
Advanced Engineering Materials, EarlyView.This study introduces a high‐rate reactive sputtering process for CoZrO films, aimed at large‐scale production of on‐chip magnetic components compatible with complementary metal oxide semiconductor (CMOS) fabrication. Characterization of the deposited films reveals that ideal magnetic properties require chemical compositions in a narrow Co:O range and ...

Energies, 2018 Behaviour of flow resistance with velocity is still undefined for post-laminar flow through coarse granular media. This can cause considerable errors during flow measurements in situations like rock fill dams, water filters, pumping wells, oil and gas ...

Computer program for calculating laminar, transitional, and turbulent boundary layers for a compressible axisymmetric flow [PDF]
, 1974 Finite-difference computer program calculates viscous compressible boundary layer flow over either planar or axisymmetric surfaces. Flow may be initially laminar and progress through transitional zone to fully turbulent flow, or it may remain laminar ...

Mist Flow Visualization for Round Jets in Aerosol Jet Printing
, 2018 With the microdroplets of water serving as light scattering particles, the mist flow patterns of round micro-jets can be visualized using the Aerosol Jet(R) direct-write system. The visualization images show that the laminar mist jet appears to extend to

Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Numerical Study of Entropy Generation in a Flowing Nanofluid Used in Micro- and Minichannels
Entropy, 2013 This article mainly concerns theoretical research on entropy generation influences due to heat transfer and flow in nanofluid suspensions. A conventional nanofluid of alumina-water (Al2O3-H2O) was considered as the fluid model.

Direct Consolidation of Copper–Graphene Composite by Rotary Swaging
Advanced Engineering Materials, EarlyView.The applicability of the rotary swaging method for preparation of electroconductive copper–graphene composite by direct consolidation of powders is proven. The consolidated material features advantageous microstructure featuring fine grains and twins, with homogeneous distribution of graphene, primarily along the twin boundaries, which contribute to ...

Laminar Flow in a Corrugated Pipe
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1979 An analysis is made of steady laminar flow in pipes with axially symmetric and non-symmetric wavy walls. Secondary flow patterns and friction factors are obtained for the case of small amplitude waviness. When kRe (k: the pipe wall wave number, Re: Reynolds number) is large, the adaptation of wall waviness to secondary flow is delayed due to the ...

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams
Advanced Engineering Materials, EarlyView.The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.
