  • Aerodynamic interference between high-speed slender bodies 
    Chaplin, Ross (Cranfield University, 2009-12)
    Significant aerodynamic interference can occur between high-speed bodies in close proximity. A complex flowfield develops where shock and expansion waves from a generator body impinge upon the adjacent receiver body. The ...
  • Aerodynamics of vortex ingestion for aero-engines 
    McLelland, Grant (Cranfield University, 2013-12)
    The potential impact of inlet flow distortion on the stability and performance of aircraft engines remains a key concern for engine-airframe integration. Current and future configurations, such as Unmanned Combat Air ...
  • Analysis and control of resonant cavity flows 
    Roberts, David (Cranfield University, 2013)
    Recently, the trend for the internalisation of stores within an aircraft fuselage has led to a renewed interest in the field of cavity aero-acoustics. Many modern military aircraft, including recent unmanned combat ...
  • CFD design analysis of ventilated disc brakes 
    Pulugundla, Gautam (Cranfield University, 2008)
    This thesis reports the numerical investigation of the automotive ventilated disc brake rotor. Disc brakes operate on the principle of friction by converting kinetic energy into heat energy. The main objective of a disc ...
  • Contra-rotating open rotor reverse thrust aerodynamics 
    McCarthy, Martin (Cranfield University, 2011-06)
    Reverse thrust operations of a model scale Contra-Rotating Open Rotor design were numerically modelled to produce individual rotor thrust and torque results comparable to experimental measurements. The aims of this ...
  • Effect of swirl distortion on gas turbine operability 
    Mehdi, Ahad (Cranfield University, 2014-05)
    The aerodynamic integration of an aero-engine intake system with the airframe can pose some notable challenges. This is particularly so for many military air- craft and is likely to become a more pressing issue for both ...
  • Intake Ground Vortex Aerodynamics 
    Murphy, John (Cranfield University, 2008-12)
    When an aircraft is operating in static or near static conditions during taxiing or take-o a vortex can form between the ground and the intake. With engine diameters increasing, intakes are moving non-dimensionally ...
  • Lateral jet interaction with a supersonic crossflow 
    Christie, Robert (Cranfield University, 2010-10)
    A lateral jet in a supersonic crossflow creates a highly complex three-dimensional flow field which is not easily predicted. The aim of this research was to assess the use of a RANS based CFD method to simulate a lateral ...
  • Numerical simulations of the wing wake and tip vortex for air-to-air refuelling 
    Miranda, Alice (Cranfield University, 2012-10)
    The present research was carried out in the framework of the ASTRAEA II project, in collaboration with Cobham Mission Equipment. One part of the overall ASTRAEA II project is to design an autonomous air-refuelling ...
  • Passive flow control devices for a multi megawatt horizontal axis wind turbine 
    Vimalakanthan, Kisorthman (Cranfield University, 2014-03)
    Renewable energy is an environmentally friendly alternative to the use of fossil fuels. In response to reducing the dependency on fossil fuels, the European Wind Energy Association (EWEA) has made a policy to increase ...
  • Reduced-order modelling for high-speed aerial weapon aerodynamics 
    Mifsud, Michael (Cranfield University, 2008-10)
    In this work a high-fidelity low-cost surrogate of a computational fluid dynamics analysis tool was developed. This computational tool is composed of general and physics- based approximation methods by which three ...
  • Refuelling tanker aerodynamics and hose characteristics 
    Liggieri, Antonio (Cranfield University, 2012-12)
    The present work is conducted within the context of air to air refuelling technologies and aims at the development of an understanding of a typical refuelling tanker wake like that of an A330 [54] and the A400M [54]. The ...
  • Tightly-wound vortex and self-generated intake distortion effects on turbomachinery performance 
    di Cugno, Domenico (2013-07)
    Current developments of civil and military applications may require the installation of aero-engines embedded into the aircraft structure. Consequently, complex diffusing Sducts are necessary to convey air from the intake ...
  • Unsteady aerodynamics of high work turbines 
    Richardson, David (Cranfield University, 2009-10)
    One method aircraft engine manufactures use to minimize engine cost and weight is to reduce the number of parts. A significant reduction includes reducing the turbine blade count or combining two moderately loaded turbines ...
