  • Condition monitoring philosophy for tidal turbines 
    Elasha, Faris; Mba, David; Amaral Teixeira, Joao (RAMS Consultants, 2014-07-01)
    Renewable energy is currently considered as the main solution to reduce greenhouse gas emission. This has led to great developments in the use of renewable energy for electricity generation. Among many renewable energy ...
  • Detailed study on stiffness and load characteristics of film-riding groove types using design of experiments 
    Tibos, S. M.; Georgakis, C.; Harvey, K.; Amaral Teixeira, Joao (American Society of Mechanical Engineers (ASME), 2017-04-11)
    In the application of film-riding sealing technology, there are various groove features that can be used to induce hydrodynamic lift. However, there is little guidance in selecting the relative parameter settings in order ...
  • Exploration of the possibility of acoustic emission technique in detection and diagnosis of bubble formation and collapse in valves 
    Alhashan, Taihiret; Addali, Abdulmajid; Amaral Teixeira, Joao (International Organization of Scientific Research, 2016-11-30)
    The application of acoustic emission (AE) technique in detection and monitoring of bubble formation and collapse in valves are presented in this review. The generation of AE signals and the basic compositions of AE ...
  • Heat removal in high pressure turbine seal segments 
    Alenezi, Abdulrahman H. (Cranfield University, 2017-02)
    An important parameter for turbomachinery designers is “clearance control”, because the clearances between interfaces must be set to optimum values to maximize power output, operational life and efficiency. Leakage of ...
  • A hybrid prognostic methodology for tidal turbine gearboxes 
    Elasha, Faris; Mba, David; Togneri, Michael; Masters, Ian; Amaral Teixeira, Joao (Elsevier, 2017-07-24)
    Tidal energy is one of promising solutions for reducing greenhouse gas emissions and it is estimated that 100 TWh of electricity could be produced every year from suitable sites around the world. Although premature gearbox ...
  • Tidal turbine modelling from the perspective of design and operation 
    Corsar, Michael (Cranfield University, 2016-06)
    The aim of this thesis is to study the effects of turbulent flow on a fixed pitch tidal current turbine from the perspective of turbine design and operation. A prototype turbine, Deltastream as it is known, is being ...
