An improved generic Johnson-Cook model for the flow prediction of different categories of alloys at elevated temperatures and dynamic loading conditions
(
Elsevier
, 2021 , Article)
This paper presents a generic model for material flow prediction based on the well-known Johnson-Cook model.
The model is developed to precisely predict the flow behavior of various categories of alloys. The coupled ...
Optimal control and duality-based observer design for a hyperbolic PDEs system with application to fixed-bed reactor
(
Taylor and Francis Ltd.
, 2021 , Article)
This paper is devoted to the design of an optimal infinite-dimensional Luenberger observer combined with a linear-quadratic state feedback controller for a system of hyperbolic PDEs. The design is based on the duality fact ...
Photoelectrocatalytic hydrogen production on ternary Co-Pi/Ag/TiON nanotube array photocatalysts
(
John Wiley and Sons Ltd
, 2021 , Article)
Ternary Co-Pi-Ag/TiON photocatalysts were designed and fabricated by a facile precipitation and electrochemical strategy. The results showed the superiority of the Co-Pi-Ag/TiON as a promising photoanode for photoelectrochemical ...
Combustion and emissions of a gas-to-liquid diesel engine utilizing optimized spiral-helical intake manifold designs
(
American Society of Mechanical Engineers (ASME)
, 2021 , Article)
Two simultaneous strategies were used to reduce diesel engine emissions. Optimized manifold designs were used with gas-to-liquid (GTL) fuel and its blend with diesel fuel. Six new spiral-helical manifolds were tested, which ...
Investigating the Potential of Recycling Flare-Source Hydrocarbon Gases in an Industrial Burner
(
American Society of Mechanical Engineers (ASME)
, 2021 , Article)
Flare gas is considered a global environmental concern. Flaring contributes to wasting limited material and energy resources, economic loss, and greenhouse gas emissions. Utilizing flared gas as a fuel feed to industrial ...
Effect of Utilizing a Novel Intake Manifold Design on Smoke Emissions and Particulate Size Distributions of a Gas-to-Liquid Diesel Engine
(
American Society of Mechanical Engineers (ASME)
, 2021 , Article)
Smoke emissions and particulate matter (PM) size distributions were investigated on a direct-injection (DI) single-cylinder diesel engine running on both gas-to-liquid (GTL) and diesel fuels utilizing a novel spiral-helical ...
Catalytic hydrothermal liquefaction of biomass into bio-oils and other value-added products – A review
(
Elsevier Ltd
, 2021 , Article)
Hydrothermal liquefaction (HTL) is an effective method for the conversion of biomass into biofuel involving moderate temperature and high pressure. However, the yield and quality of bio-oil are not sufficient for ...
Multilayered-quality education ecosystem (MQEE): an intelligent education modal for sustainable quality education
(
Springer
, 2021 , Article)
Sustainable quality education is a big challenge even for the developed countries. In response to this, education 4.0 is gradually expanding as a new era of education. This work intends to unfold some hidden parameters ...
Design and thermo-economic evaluation of an integrated concentrated solar power – Desalination tri-generation system
(
Elsevier Ltd
, 2021 , Article)
In this work, a concentrated solar power (CSP) tri-generation system that is capable of the simultaneous production of steam, power and freshwater is introduced. The abundantly available direct normal irradiance can ...
A universal transportation model for reverse osmosis systems
(
Elsevier Ltd
, 2021 , Article)
This paper presents a new transport model for reverse osmosis (RO) systems, which combines irreversible thermodynamics, together with solution-diffusion theory. The simplifications adopted by the classical theory for ...
