    Numerical Simulation and Investigation of Impact of Climate Change on Probability Occurrence of Tropical Cyclone in Sea of Oman and Persian Gulf

    , M.Sc. Thesis Sharif University of Technology Ilami, Dariush (Author) ; Abbaspour Tehrani Fard, Madjid (Supervisor)
    Super cyclone GONU formed on June 2007 has been recognized the strongest tropical cyclone in the North Indian Ocean (NIO). The aim of this study is to numerically simulate the cyclone GONU and its resulting waves in the southern seas of Iran leading to the best parametric model to simulate future occurrence of tropical cyclones (TCs) in the NIO. In this regard, the best track data of the cyclone is extracted from Indian Meteorological Department (IMD). The cyclone GONU wind field is simulated by Young and Sobey, Holland, and Rankin models in order to determine the most appropriate model which is then considered for regenerating cyclonic wind fields over the Makran coastline and the sea of... 

    The Effects of PTO Characteristics on Performance of a Floating Point Absorber Wave Energy Converter

    , M.Sc. Thesis Sharif University of Technology Ramazani, Arman (Author) ; Behzad, Mahdi (Supervisor) ; Abazari, Abuzar (Supervisor)
    In recent years, the challenges of using fossil energy causes governments and researchers to focus on renewable energies. In this regard, one of the strategies for generating power is using wave energy converters. The aim of present study is modeling frequency and time domain analysis of the wave energy converter. the study focuses on the effect of Power-Take-Off system on the output power and efficiency under the Macoran sea waves. First, the concept of wave converters is explained and the commercialized ones are introduced. Then the related previous works are reviewed and the wave theories are briefly presented. In the following, a specified one-degree-of-freedom converter is modeled in...
