Sustainability Assessment in Aviation Industry: A Mini- Review on the Tools, Models and Methods of Assessment
(
IEOM Society International
, 2020 , Conference Paper)
Sustainable aviation practices have significantly reduced Greenhouse Gas (GHG) emissions over the years. However, these practices have not shaped the aviation industry in achieving the United Nations Sustainable Development ...
Tools and Techniques for Food Security and Sustainability Related Assessments: A focus on the Data and Food Waste Management System
(
IEOM Society International
, 2020 , Conference Paper)
Achieving global food security requires addressing series of challenges, from food waste accumulation in the food
supply chain (FSC) to tackling the gender disparities and climate-related concerns to promote sustainable ...
Large-eddy simulation of the flow in Z-Shape duct
(
Cogent OA
, 2020 , Article)
A numerical study is conducted of the transient flow in a z-shape three-dimensional duct using large-eddy simulation (LES) with dynamic eddy viscosity subgrid-scale (SGS) model with a fully structured grid system. The ...
Hysteresis behaviour of different magnetorheological elastomer models: Modelling and simulation
(
EXTRICA
, 2020 , Conference Paper)
Smart materials are materials by which their properties can be altered due to external stimuli such as temperature, pressure, and magnetic field. Magnetorheological Elastomer (MRE) is a type of smart composite material ...
Estimation and measurement of effective line mobility on a non-deterministic thin plate excited by a piezoelectric patch
(
EXTRICA
, 2020 , Article)
This paper derived the expression to estimate the effective line moment mobility of a non-deterministic thin plate under moment excitation by a piezoelectric patch actuator. The piezoelectric patch actuator is assumed to ...
Dynamic Response of a Rotating Assembly under the Coupled Effects of Misalignment and Imbalance
(
Hindawi Limited
, 2020 , Article)
In rotating machinery, the second most common fault after imbalance is misalignment. Misalignment can have a severe impact on equipment and may reduce the machine's lifetime considerably. In this paper, the simultaneous ...
Turbulence Modeling Using Z-F Model and RSM for Flow Analysis in Z-SHAPE Ducts
(
Wiley
, 2020 , Article)
Turbulent flow in Z-shape duct configuration is investigated using Reynolds stress model (RSM) and ζ-f model and compared to experimental results. Both RSM and ζ-f models are based on steady-state RANS solutions. The focus ...
A combined thermo-mechanical refrigeration system with isobaric expander-compressor unit powered by low grade heat – Design and analysis
(
Elsevier
, 2020 , Article)
Refrigeration and air conditioning systems consume about 17% of the world-wide electricity and their conventional refrigerants cause ozone depletion and global warming. In this study a novel thermo-mechanical refrigeration ...
Cellular uptake and retention of nanoparticles: Insights on particle properties and interaction with cellular components
(
Elsevier Ltd
, 2020 , Article)
The utilization of nanomaterials in the biological and medical field is quickly progressing, particularly in areas where traditional diagnostics and treatment approaches have limited success. The success of nanomaterials ...
Improving mechanical, thermal and damping properties of niti (Nitinol) reinforced aluminum nanocomposites
(
MDPI AG
, 2020 , Article)
In the present study, Ni50Ti50 (NiTi) particle reinforced aluminum nanocomposites were fabricated using microwave sintering and subsequently hot extrusion. The effect of NiTi (0, 0.5, 1.0, and 1.5 vol %) content on the ...
