An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced 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

The enhanced cooling of heated blocks mounted on the wall of a plane channel filled with a porous medium

open access: yesRevue des Énergies Renouvelables, 2008
This is a two dimensional numerical simulation of the laminar air forced convection cooling of six blocks mounted on the lower wall of a plane horizontal channel filled (or not filled) with a porous medium.

X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, EarlyView.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Numerical investigation of mixed convection of nanofluid flow in a trapezoidal channel with different aspect ratios in the presence of porous medium

open access: yesCase Studies in Thermal Engineering, 2021
In this study, a numerical investigation of mixed convection of nanofluid flow in a trapezoidal channel with two different aspect ratios of 0.3 and 0.5 with the presence of porous media is investigated.

On the Onsetof Thermal Instability in a Low Prandtl Number Nanofluid Layer in a Porous Medium

open access: yes, 2015
Thermal instability in a low Prandtl number nanofluid in a porous medium is investigated by using Galerkin weighted residuals method for free-free boundaries. For porous medium, Brinkman-Darcy modelis applied.

Asymptotic analysis of surface waves at vacuum/porous medium and liquid/porous medium interfaces

open access: yesContinuum Mechanics and Thermodynamics, 2002
Surface waves at a free interface of a saturated porous medium and at an interface between a porous medium and a liquid are investigated. Existence and peculiarities of such surface waves are revealed. At a free interface two types of surface waves are proved to be possible: the true Stoneley wave, propagating almost without attenuation, and the leaky ...
