  • Parametric Study of Hot Rolling Process by the Finite Element Method 

    Shahani, A.R.؛ Nodamaie, S. A.؛ Salehinia, I. (Sharif University of Technology, 2009-04-01)
    Abstract. In the present investigation, a hot rolling process of AA5083 aluminum alloy is simulated. The approach is based on the thermo-mechanical analysis of the problem using the Finite Element Method (FEM). The ...

  • Simulation of Turbulent Flow Through Porous Media Employing a v2f Model 

    Ashoor, M.؛ Bahoosh Kazerooni, R. (Sharif University of Technology, 2009-04-01)
    Abstract. In this article, a v2f model is employed to conduct a series of computations of incompressible ow in a periodic array of square cylinders simulating a porous media. A Galerkin/least-squares nite element ...

  • The E ect of Wake Flow and Skew Angle on the Ship Propeller Performance 

    Ashoor, M. (Sharif University of Technology, 2009-04-01)
    Abstract. This paper provides an investigation into the in uence of wake and skew on a ship propeller performance, based on the potential Boundary Element Method (BEM). Two types of in ow wake from a ship (i.e. Seiun-Maru ...

  • Free Vibration Analysis of Rotating Laminated Cylindrical Shells Under Di erent Boundary Conditions Using a Combination of the Layerwise Theory and Wave Propagation Approach 

    Ashoor, M. (Sharif University of Technology, 2009-04-01)
    Abstract. In this paper, vibration analysis of rotating laminated composite cylindrical shells using a combination of the layerwise theory and wave propagation approach is investigated. This combination enables us to ...

  • Direct Design of Branched Ducts 

    Ashrafizadeh, A.؛ Taiebi-Rahni, M.؛ Ghadak, F. (Sharif University of Technology, 2009-04-01)
    Abstract. A fully coupled formulation of thermo- uid shape design problems has recently been developed in which the unknown nodal coordinates appear explicitly in the formulation of the problem. This direct design" ...

  • Micro Resonator Nonlinear Dynamics Considering Intrinsic Properties 

    Ashoor, M.؛ Tadayon, M.A. (Sharif University of Technology, 2009-04-01)
    Abstract. One of the most important phenomena to a ect the motion behaviour of Micro Resonators is their thermal dependency. This has recently received the attention of researchers widely. A thermal phenomenon has two ...

  • Spectator Model in D Meson Decays 

    Mehrban, H. (Sharif University of Technology, 2009-04-01)
    Abstract. In this research, the e ective Hamiltonian theory is described and applied to the calculation of current-current (Q1;2) and QCD penguin (Q3; ;6) decay rates. The channels of charm quark decay in the quark ...
