Numerical simulation of pressure loss in porous media in oscillating flow
(World Scientific and Engineering Academy and Society, 2018)
In this study, the pressure loss in two types of porous media for both unidirectional and oscillatory flows is analyzed using commercial software Comsol©. The numerical results are compared with those obtained in the ...
Spacetimes admitting the Z-symmetric tensor
(Natl Inquiry Services Centre Pty Ltd, 2020)
This paper aims to introduce the spacetimes admitting the Z-symmetric tensor. We investigate the properties of these spacetimes for a perfect fluid and a pressureless perfect fluid (a dust). Some theorems about the properties ...
Assessment of the impact of fouling on vessel energy efficiency by analyzing ship automation data
(Elsevier Sci Ltd, 2020)
Shipbuilding and shipping areas are technically dependent to each other since shipping is the end user in the shipbuilding industry. One of the biggest maritime challenges arose due to regulations about emissions and has ...
An investigation of marine waste heat recovery system based on organic Rankine cycle under various engine operating conditions
(Sage Publications Ltd, 2019)
Energy-saving, stricter regulations on pollution prevention, increasing energy efficiency and reducing operational costs have become common and primary issues for maritime industry, recently. One of the methods to improve ...
Structure of trimers of group-2B metal dihalides from relativistic density-functional calculations
(Taylor & Francis Ltd, 2015)
We report density-functional calculations, carried out in a quantum-chemical approach using localised-Gaussians expansions of the Kohn-Sham orbitals, for metal dihalides trimers (MX2)(3), where X=Cl, Br, or I and M=Zn, Cd, ...
The origins of tetrahedral coordination in molten and glassy ZnCl2 and other group-2B metal dihalides
(Elsevier, 2014)
We report the results of first-principles calculations carried out within a relativistic density-functional method, on the molecular trimers of the MX2 compounds (with M = Zn or Cd and X = Cl, Br, or I), showing how a ...
Fluorescence Study of Film Formation from PS Latex-TiO2 Composites: Effects of TiO2 Content, Film Thickness and Particle Size
(Amer Scientific Publishers, 2015)
Steady-state fluorescence (SSF) technique in conjunction with UV-visible (UVV) technique, atomic force microscope (AFM) and scanning electron microscope (SEM) is used for studying film formation from TiO2 covered polystyrene ...
Study of Film Formation From PS Latex/TiO2 Nanocomposites; Effect of Latex Size and TiO2 Content
(Wiley, 2014)
In this work, we investigated the film formation from polystyrene (PS) latex/TiO2 nanocomposites using the steady state fluorescence (SSF) and UV-vis (UVV) techniques depending on PS particle size and TiO2 content. The ...
Molecular, vibrational and electronic structure of 4-bromo-2-halogenobenzaldehydes: Halogen and solvent effects
(Walter De Gruyter Gmbh, 2017)
The halogen and solvent effects on the structure of 4-bromo-2-halogenobenzaldehydes [C7H4BrXO; X = F (BFB), Cl (BCB) or Br (BBB)] were investigated by the density functional theory (DFT) and time-dependent density functional ...
Fluorescence study of effect of particle size in PS latex/Al2O3 nanocomposite films
(Maney Publishing, 2015)
Steady state fluorescence and BioUV-Visible techniques were used to study film formation of polystyrene (PS) latex and Al2O3 composites depending on PS particles size and Al2O3 content. Two film series (SmPS/Al2O3 and ...
