Powering and seakeeping characteristics of a displacement hullform with waterline parabolization
(2010)
Waterline parabolization is a design procedure used for displacement vessels to decrease the wave resistance of the hullform through the addition of amidships bulbs. The bow and shoulder wave system of a parent hullform ...
A Detailed Analysis of Ideal Rankine Steam Cycle
(Amer Soc Naval Eng Inc, 2016)
In this theoretical work, the ideal Rankine cycle using water vapor is studied in detail considering a condenser pressure range of 10-80 kPa, a boiler pressure range of 3-15 MPa and a superheater temperature range of 350-600 ...
Fuel or acceleration: A pareto design procedure for ships
(CRC Press/Balkema, 2018)
Ship design, as all other designs, is continuously changing. The design method used in this study is to calculate ship resistance and ship motion with algorithms and then to calculate the dynamic effects such as acceleration, ...
Comparison of two base-potentials for a slender-body method
(2012)
The effects of two base-potentials on the accuracy of a slender-body method are studied in this paper. In the formulation for this method which is developed for the slender ships, the velocity potential is decomposed into ...
Second-order wave diffraction by horizontal rectangular barriers
(2011)
A complete second-order analytical solution for the nonlinear diffraction of waves by 2-D rectangular cylinders fixed at the free surface of finite-depth waters is presented. As a sequel to a previous linear treatment of ...
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 ...
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 ...
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 ...
Hydrodynamic aspects of oscillating flow through porous media consisting of steel spheres
(Springer International Publishing, 2014)
Hydrodynamic aspects of oscillating flow through porous media are investigated within the scope of this experimental work where water is used as the flow medium. Friction factors are found reducing the data of hydrodynamic ...
