Applying zoning method for numerical modeling of two immiscible fluid interface motion in an underwater tank using BEM

M. Ghodsi Hasanabad

Volume 2, Issue 2 , June 2012, Pages 135-140

  In this study, boundary element method was used to model sea wave propagation on a hemisphere shape under water tank and oil-water common surface oscillation in the tank. Also, kinematic and dynamic oundary conditions of free surface and common surface of oil and water were discritized by Finite ...  Read More

Simulation of static sinusoidal wave in deep water environment with complex boundary conditions using proposed SPH method

A. H. Javid; M. Abbaspour; S. A. Mirbagheri; H. JanfeshanAraghi

Volume 2, Issue 2 , June 2012, Pages 141-148

  The study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. Therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave ...  Read More

A novel boundary condition for the simulation of the submerged bodies using lattice boltzmann method

Sh. Sharafatmandjoor; F. Sabetghadam; H. R. Fathalizadeh; A. Shahirpour

Volume 2, Issue 2 , June 2012, Pages 149-152

  In this study, we proposed a novel scheme for the implementation of the no-slip boundary condition in thelattice Boltzmann method (LBM) . In detail , we have substituted the classical bounce-back idea by the direct immersed boundary specification . In this way we construct the equilibrium density ...  Read More

Comparison between linear and nonlinear models for surge motion of TLP

M. R. Tabeshpour; R. Shoghi

Volume 2, Issue 2 , June 2012, Pages 153-162

  Tension-Leg Platform (TLP) is a vertically moored floating structure. The platform is permanently mooredby tendons. Surge equation of motion of TLP is highly nonlinear because of large displacement and it should be solved with perturbation parameter in time domain. This paper compare the dynamic ...  Read More

Evaluating the results of Hormuz strait wave simulations using WAVEWATCH-III and MIKE21-SW

F. S. Sharifi; M. Ezam; A. Karami Khaniki

Volume 2, Issue 2 , June 2012, Pages 163-170

  In this study, the capabilities of WAWEWATCH-III and MIKE21-SW for predicting the characteristics ofwind-generated waves in Hormuz Strait are evaluated. The numerical models have been set up using Input data including GFS wind with 5° spatial resolution and 6 hours time intervals, along with ...  Read More

Study of Linear Alkyl Benzene (LABs) as molecular marker of sewage pollution in Bivalves Mollusk “AnodontaCygnea” in Anzali lagoon

A. Mashinchian Moradi; A. H. Dashti; M. R. Fatemi; P. Aberoumand Azar

Volume 2, Issue 2 , June 2012, Pages 171-176

  Tracking and determining the amount and types of urban sewage that is being releasing to the environment is important in planning for wastewater treatment systems and water quality control. In this research, in four stations of Anzali Lagoon, (by means of a gas chromatograph device with mass ...  Read More
