Development of computationally efficient augmented Lagrangian SPH for incompressible flows and its quantitative comparison with WCSPH simulating flow past a circular cylinder
(Wiley, 2020)
In Lagrangian particle-based methods such as smoothed particle hydrodynamics (SPH), computing totally divergence-free velocity field in a flow domain with the smallest error possible is the most critical issue, which might ...
Numerical simulations of multi-phase electro-hydrodynamics flows using a simple incompressible smoothed particle hydrodynamics method
(Pergamon-Elsevier Science Ltd, 2021)
Practically, every processing technology deals with complex multi-phase flows and predicting the fluid flow behavior is crucial for these processes. Current study discusses the application of a mesh-less numerical methodology, ...
An Iterative Algorithm for Imaging of Rough Surfaces Separating Two Dielectric Media
(IEEE-Inst Electrical Electronics Engineers Inc, 2021)
In this article, an efficient algorithm for the reconstruction of a 1-D random rough surface profile separating two lossy dielectric half-spaces is presented. First, the general scattering problem is formulated by the use ...
Multi Objective Design of Ships; A Pareto Procedure
(Springer Science and Business Media Deutschland GmbH, 2021)
The design calculations for a displacement type vessel and for a planing hull are done for the main dimensions, starting with a fuel and acceleration criteria. A large number of vessels are simulated with the help of ...
A case study on oil pollution in Istanbul Strait: Revisiting 1994 Nassia tanker accident by utilising Potential Incident Simulation Control and Evaluation System (PISCES-II) simulation. What would be different in terms of response if Nassia accident happened today?
(Pergamon-Elsevier Science Ltd, 2020)
Turkey, with her two important straits, is geographically in the middle of one of the major transportation routes and will continue to face risks the oil tankers pose in those sensitive areas. This paper revisits the site ...
Calculation of the inverse relaxation time and the activation energy as a function of temperature for the Raman modes close to the phase transitions in solid nitrogen
(Elsevier, 2021)
The inverse relaxation time is calculated as a function of temperature for the transitions of alpha - beta (P = 0) and epsilon-delta(loc)-delta (at constant pressures) in the solid N-2. For this calculation, the observed ...
Liquid-(Solid plus Liquid) Transitions in a Two-Component System of (CH3)CCl3 + CCl4
(Springer/Plenum Publishers, 2020)
Liquid-(solid + liquid) transitions are studied in (CH3)CCl3 + CCl4 by using the Landau phenomelogical model. The Gibbs energy is expanded in terms of the orientational disorder (OD) parameters for the transitions of the ...
Three-parameter (3P) weibull distribution for characterization of strength of ceramics showing R-Curve behavior
(Elsevier Sci Ltd, 2021)
Strength distribution of advanced ceramics is commonly characterized by two-Parameter (2P) Weibull distribution. However, deviation of strength distribution from 2P-Weibull distribution may occur in ceramics due to various ...
Analysis of the residual stresses and deformations during the autogenous GTAW process
(Emerald Group Publishing Ltd, 2021)
Purpose The gas tungsten arc welding (GTAW) process is a widely used process that produces quality weldments. But the high heat generation from the GTAW arc can cause extreme temperatures as high as 20,000 degrees C. 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 ...
