Validation of CFD simulation for flat plate solar energy collector
(
Elsevier
, 2007 , Article)
The problem of flat plate solar energy collector with water flow is simulated and analyzed using computational fluid dynamics (CFD) software. The considered case includes the CFD modeling of solar irradiation and the modes ...
A novel solar integrated distillation and cooling system – Design and analysis
(
Elsevier
, 2020 , Article)
To meet the high cooling and fresh water demands in hot and arid regions, a novel integrated solar cooling and solar distillation system is introduced. The system consists of a solar ejector cooling system integrated with ...

(
Springer Nature
, 2019 , Article)
We report the synthesis of high soluble poly(aniline-co-o-hydroxyaniline) copolymers with varying the amount of o-hydroxyaniline (20, 40, 60, and 80 %) and referred as PA-co-o-HA20, PA-co-o-HA40, PA-co-o-HA60, and PA-co-o-HA80 ...
Cyclic voltammetry and XPS studies of poly (aniline-co-3-aminophenol)
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
In the present work, we prepared enormously soluble poly (aniline-co-3-aminophenol) (PA-co-3-AP) copolymers via a simple chemical oxidative method with aniline and 3-aminophenol, and their properties are compared with ...
Polymeric smart coatings containing modified capped halloysite nanotubes for corrosion protection of carbon steel
(
Springer
, 2023 , Article)
A newly designed smart self-healing epoxy coating system comprised of modified halloysite nanotubes (HNTs) having capping is proposed for corrosion protection of steel. In the first step, HNTs were loaded with 8-hydroxyquinoline ...
Towards a simplified technique for crack recognition in gearing systems
(
Academie des sciences
, 2022 , Article)
This paper presents a simple and effective method to identify and quantify the existence of cracks in the teeth roots of spur gears. The problem was numerically analyzed through finite element-based simulation with SolidWorks ...

, 2023 , Article)
Mega sporting events (MSEs) such as the FIFA World Cup and the Olympics always attract people around the world to visit the hosting country, boosting its tourism and business, and leaving a positive legacy. However, such ...
The probabilistic nature of ignition of turbulent highly-strained lean premixed methane-air flames for low-emission engines
(
Elsevier
, 2014 , Article)
The probabilistic nature of ignition of turbulent highly-strained lean premixed flames has been investigated. Two flow configurations have been considered in this study; counter-flow and bluff-body flames. Different ...
A calcium peroxide incorporated oxygen releasing chitosan-PVA patch for Diabetic wound healing
(
Elsevier
, 2023 , Article)
Impaired wound healing is a major healthcare problem in patients with diabetes often resulting in gangrene, microbial infection and amputation of affected limb. The delay or absence in healing process arises from several ...
