Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser
(
Elsevier
, 2016 , Article)
In this study, we present a numerical investigation of active surge control and performance improvement for an aero engine centrifugal compressor (NASA CC3) using self-recirculating bleed slots with different bleeding ...
Time-domain simulation of second-order irregular wave diffraction based on a hybrid water wave radiation condition
(
Elsevier
, 2016 , Article)
A time-domain second-order method is presented to simulate three-dimensional wave–body interaction. In the approach, Taylor series expansions are applied to the free surface boundary conditions, and a Stokes perturbation ...
Image Local Features Description through Polynomial Approximation
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
This work introduces a novel local patch descriptor that remains invariant under varying conditions of orientation, viewpoint, scale, and illumination. The proposed descriptor incorporate polynomials of various degrees to ...
Development of titanium dioxide nanowire incorporated poly(vinylidene fluoride–trifluoroethylene) scaffolds for bone tissue engineering applications
(
Springer New York LLC
, 2019 , Article)
Critical size bone defects that do not heal spontaneously are among the major reasons for the disability in majority of people with locomotor disabilities. Tissue engineering has become a promising approach for repairing ...
Ethanol dehydrogenation mechanism on cuni catalysts for hydrogen production
(
TechConnect
, 2016 , Conference Paper)
Ethanol dehydrogenation mechanism was investigated over catalysts containing Cu and Ni metals prepared by solution combustion synthesis. In situ DRIFTS studies were conducted on individual metals (Cu and Ni) as well as on ...
A low-cost test rig for impact experiments on a dummy head
(
Elsevier Ltd
, 2019 , Article)
Anthropomorphic test dummies are commonly used to evaluate the potential harm to humans due to dangerous scenarios, such as that due to car accidents. Furthermore, they have been used in sports to evaluate the efficacy of ...
Constitutive models for the prediction of the hot deformation behavior of the 10%Cr steel alloy
(
MDPI AG
, 2019 , Article)
The aim of this paper is to establish a reliable model that provides the best fit to the specific behavior of the flow stresses of the 10%Cr steel alloy at the time of hot deformation. Modified Johnson-Cook and strain-compensated ...
Solar Energy For More Eco-friendly Mosque In Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
There is mounting evidence that the global warming and, consequently, the climate changes are anthropogenic and attributed to fossil fuel consumption. Therefore, it is mandatory to find alternative solutions that can replace ...
Synthesis, characterization, and properties of nickel-cobalt layered double hydroxide nanostructures
(
Royal Society of Chemistry
, 2017 , Article)
Nickel-cobalt layered double hydroxides (Ni-Co-LDH) have recently been examined for their potential as battery-type hybrid supercapacitors made from metal hydroxide electrode materials, due to their unique spatial structure, ...
Nature-inspired cellular structure design for electric vehicle battery compartment: Application to crashworthiness
(
MDPI AG
, 2020 , Article)
This paper discusses the potential of using lightweight nature-inspired cellular structured designs as energy absorbers in crashworthiness applications for electric vehicles (EV). As EVs are becoming popular with their ...
