The Effect of Axial Spacing of Constant and Variable Blockages on the Deflagration-to-Detonation Transition in a Pulse Detonation Engine
… was conducted into the effects of obstacle spacing on the deflagration-to-detonation transition section length in a pulse detonation engine. Testing was conducted with one hundred and ninety-five different obstacle, and spacing configurations. The configurations included constant, as well as …

Impact of unsteady flow processes on the performance of a high speed axial flow compressor
… vane/rotor configurations with different axial spacing between vane and rotor are considered. The numerical simulations of the two configurations are used to determine the effect of axial blade row spacing on the level of entropy generation and the flow mechanisms that affect stage …

A CFD analysis of the pressure drop through misaligned Stirling engine regenerators
… was also used to determine the influence of axial spacing on the pressure drop, and it was found to be dependent on the misalignment, with pressure loss reductions only being realized in highly misaligned cases. As a result of this thesis, Stirling designers can confidently disregard …

Benchmarking of Computational Models Against Experimental Data for Adiabatic Film-Cooling Effectiveness for Large Spacing Compound Angle Full Coverage Film Cooling Arrays
… of blowing ratio, surface angle, and hole spacing for two full coverage geometries composed of cylindrical staggered holes at a compound angle of 45 degrees. These holes varied parametrically the inclination angle to be 30 and 45 degrees, while maintaining a lateral and axial spacing of …

Simulation of 3-D viscous compressible flow in multistage turbomachinery by finite element methods
… the upstream and downstream rows. The effects of axial spacing, blade count, clocking (relative position of follow-up rotors with respect to wakes shed by upstream ones), and levels of unsteadiness may have a significance on performance and durability. In this Thesis, finite element formulations …

Flow in Multistage Transonic Compressors
… part of the thesis the effect of the IGV-Rotor axial gap on the compressor efficiency, and the dynamic blade loading, is investigated in multistage unsteady simulations. This shows that a reduced IGV-Rotor axial spacing gives an improvement in the efficiency but leads to an increase in the …
