  • The effects of wear on abradable honeycomb labyrinth seals 
    Collins, Dermot (Cranfield University, 2007-03)
    This thesis reports on work undertaken to understand the effects, due to wear, on the performance of abradable honeycomb labyrinth seals. The phenomena studied are aerodynamic in nature and include compressible flow, ...
  • Heat removal in axial flow high pressure gas turbine 
    Alhajeri, Hamad (Cranfield University, 2016)
    The demand for high power in aircraft gas turbine engines as well as industrial gas turbine prime mover promotes increasing the turbine entry temperature, the mass flow rate and the overall pressure ratio. High turbine ...
  • 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 ...
  • Optimisation of bidrectional impulse turbines for wve power generation 
    Banks, K (Cranfield University, 2009-03)
    The generation of electricity from ocean waves using oscillating water column (OWC) wave energy converters is currently uneconomic due to the high capital cost and low efficiencies of such devices. The bidirectional air ...
  • 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 ...
  • Transition Modelling for Axial Compressor Flows 
    Beevers, A. (Cranfield University, 2008-11-03)
    Abstract The application of Menter's transition model (Menter et al. (2004a), here-after known as the ץ - θ model) available in the CFX CFD code, for use within an axial compressor design group was studied. Simulations ...
  • Unsteadiness In An Embedded Axial Compressor Stage 
    Naylor, Edward (Cranfield University, 2008-02)
    Previous research on blade boundary layers in turbomachinery have been recognised to crucially influence the stability and performance of the gas turbine components. The interactions between rotating and stationary blade ...
