  • Holzhauer, Eva (Cranfield University, 2012-12)
    The early effects of the global warming can be observed and people around the world are beginning to realize the seriousness of the situation. Reducing the CO2 emissions produced by fossil energy seems to be one of the ...
  • Spence, R. (Cranfield University, 2006-10)
    The operation of centrifugal pumps can generate instabilities and pressure pulsations that may be detrimental to the integrity and performance of the pump. Until recently these pressure pulsations could only be determined ...
  • Alshimmeri, Fiasael (Cranfield University, 2017-01)
    It is widely acknowledged that bearing failures are the primary reason for breakdowns in rotating machinery. These failures are extremely costly, particularly in terms of lost production. Roller bearings are widely used ...
  • 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, ...
  • 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 ...
  • Alenezi, Abdulrahman (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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
