  • Drag coefficient and strouhal number analysis of cylindrical tube in two phase flow 

    Hanafizadeh, Pedram؛ Karbalaee M., Sina؛ Sharbaf E., Behdad؛ Ghanbarzadeh, S. (University of Tehran, 2013-07-01)
    In many industrial equipment such as boilers and heat exchangers, the cylindrical tubes are exposed to the gas- liquid two phase flow. For any immersed body in flow field vortex shedding is created with a frequency ...

  • Performance assessment of a hybrid fuel cell and micro gas turbine power system 

    Sedaghat, Ahmad؛ Tahmasebi, Ahmad؛ Kalbasi, Rasool؛ Moghimi Zand, Mahdi (University of Tehran, 2013-07-01)
    In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC ...

  • Study of the performance of a solar adsorption cooling system 

    Behbahani-nia, Ali؛ Sayfikar, Mahsa (University of Tehran, 2013-07-01)
    This article presents a transient model of a solar adsorption cooling system. A computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat ...

  • Numerical investigation of clocking in a two-stage gas turbine 

    Nejat, Amir؛ Hamedi, Hossein (University of Tehran, 2013-07-01)
    Flow in the first two-stage of V 94.2 gas turbine is simulated numerically. In this turbine, the second stator is clocked relative to the first stator to different positions. Steady-state analysis was carried out by ...

  • Assessment of various rotor tip geometries on a single stage gas turbine performance 

    Nejat, Amir؛ Izadi, Ali؛ Esfahanian, Vahid (University of Tehran, 2013-07-01)
    Tip leakage loss introduces major part of losses of the rotor in axial gas turbines. Therefore, the rotor blade tip has a considerable effect on rotor efficiency. To understand the flow physics of the rotor tip leakage, ...

  • Film cooling effectiveness in single row of holes: First moment closure modeling 

    Bazdidi-Tehrani; H. Foroutan; M. Rajabi-Zargarabadi, Farzad (University of Tehran, 2013-07-01)
    The present article focuses on the evaluation of a first-moment closure model applicable to film cooling flow and heat transfer computations. The present first-moment closure model consists of a higher level of turbulent ...
