1. Frequency Analysis of a Cable with Variable Tension and Variable Rotational Speed

Moharam Habibnejad; AliAkbar Alipour

Volume 4, Issue 4 , September 2011

Abstract
  In this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using Hamilton’s principal. A modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. The natural solution is directed ...  Read More

2. Investigating the Effect of Different Boundary Conditions on the Identification of a Cavity Inside Solid Bodies

Mahmud Khodadad; Mohsen DashtiArdakani

Volume 4, Issue 4 , September 2011

Abstract
  The effect of boundary conditions on the solution of the inverse problem of identifying the geometry and location of a cavity inside an elastic solid body using displacement measurements obtained from a tension test is investigated. The boundary elements method (BEM) coupled with the genetic algorithm ...  Read More

3. THE ENERGY AND EXERGY ANALYSIS OF SINGLE EFFECT ABSORPTION CHILLER

Farshad PanahiZadeh; Navid Bozorgan

Volume 4, Issue 4 , September 2011

Abstract
  The first and second laws of thermodynamics have been employed to evaluate energy and exergetic efficiency of the single effect absorption chiller which is used for air conditioning purpose. The performance analysis has been carried out by developing a computer program in EES and modeling the chiller ...  Read More

4. Investigation of Process Parameters on Hot Ring Rolling by Coupled Thermo-Mechanical 3D-FEA

AmirHossein Gheisari; MohammadReza Forouzan; AbdolAli Maracy

Volume 4, Issue 4 , September 2011

Abstract
  Hot rolling of a large ring of titanium alloy (LRT) is a highly nonlinear incremental forming process with coupled mechanical and thermal behaviors (MTBs) which significantly affect microstructure and properties of the ring. The feed rate of idle roll and the rotational speed of driver roll have major ...  Read More

5. Comparative Investigation in a Turbine Blade Passage Flows with Several Different Turbulence Models

Mahmoud Ebrahimi; MohammadHosein Rouzbahani

Volume 4, Issue 4 , September 2011

Abstract
  In the present work a two dimensional numerical investigation of steam flows in a turbine blade passage is performed. A finite volume approach has been used and the pressure–velocity coupling is resolved using the SIMPLE algorithm. The purpose of this paper is to find that one of the used turbulent ...  Read More

6. Analysis of Two Dimensional Steady-State Heat Conduction Problems by MLPG Method

GholamHosein Baradaran; MohammadJavad Mahmoodabadi

Volume 4, Issue 4 , September 2011

Abstract
  Numerical solutions obtained by the Meshless local Petrov–Galerkin (MLPG) method are presented for two-dimensional steady-state heat conduction problems. The MLPG method is a truly meshless approach, and neither the nodal connectivity nor the background mesh is required for solving the initial-boundary-value ...  Read More
