Abstract:
We consider the stability of a thin flexible cylinder considered as a beam, when subjected to axial flow and fixed at the upstream end only. A linear stability analysis of transverse motion aims at determining the risk of flutter as a function of the governing control parameters such as the flow velocity or the length of the cylinder. Stability is analysed applying a finite-difference scheme in space to the equation of motion expressed in the frequency domain. It is found that, contrary to previous predictions based on simplified theories, flutter may exist for very long cylinders, provided th

Abstract:
Two different approaches have been used to calculate turbulent flow along a long thin cylinder where the flow is aligned with the cylinder. A boundary-layer code is used to predict the mean flow for very long cylinders (length to radius ratio of up to O(106)), with the effects of the turbulence estimated through a turbulence model. Detailed comparison with experimental results shows that the mean properties of the flow are predicted within experimental accuracy. The boundary-layer model predicts that, sufficiently far downstream, the surface shear stress will be (almost) constant. This is cons

The flow in the near wake of a square cylinder at Reynolds numbers of 205 and 225, corresponding to three-dimensional wake instability modes $A$ and $B$, respectively, and that of the square’s circumscribed circular cylinder are examined by using three-dimensional Navier–Stokes numerical simulations. At small times, prior to the streamwise vortex shedding, a self-similar velocity is observed in the wake and no significant difference is observed in the dynamics of the flows past the square and the circular cylinders. The exponential growth of the three-dimensional instability reaches a saturati

The vortex-induced vibrations of two side-by-side flexible cylinders in a uniform flow were studied using a three-dimensional direct numerical simulation at Reynolds number Re = 350 with an aspect ratio of 100, and a center-to-center spacing ratio of 2.5. A mixture of standing-traveling wave pattern was induced in the in-line (IL) vibration, while the cross-flow (CF) vibration displayed a standing-wave characteristic. The ninth vibration mode prominently occurred in both IL and CF directions, along with competition between multiple modes. Proximity effects from the neighboring cylinder caused

Abstract:
The mass transfer from an array of naphthalene-coated parallel rectangular cylinders, through which air passes in a slitlike flow, has been measured. The local Sherwood numbers indicate that the flow pattern is asymmetric in spite of using an array of two-dimensional, equally spaced identical cylinders. Smoke-wire flow visualization verifies this asymmetry, showing alternate short and long wakes around the cylinders, due probably to the instability of vortex shedding. On the side surfaces of the cylinders with the short wakes, the airflow deflects and reattaches, resulting in a high mass trans

The hydrodynamic effects of long-line mussel farms are studied through a two-pronged approach. Large-scale hydrodynamic effects are investigated through the use of field measurements, primarily at a large mussel farm in Golden Bay, New Zealand (230 long-lines, covering an area of 2.45 km by 0.65 km). The research focuses on three areas: the effect of the farm on currents, mixing and stratification, and the dissipation of wave energy.

The analytical modeling is based on three dimensional wave propagation utilizing constant complex moduli. The solution is achieved by determining the displacement and stress on the surface, and by complying with requirements at the boundary. Analysis was conducted to express displacement stresses at any point of the solid cylinder to boundary stress. Dimensionless natural frequencies and mode shapes for different circumferential and axial wave numbers are determined.

Abstract:
The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on their stability design. The cylinder response is characterized by cross-sectional ovalization, followed by buckling (bifurcation instability), which occurs on the compression side of the cylinder wall. Using a nonlinear finite element technique the bifurcation moment is calculated, the post-buckling response is determined, and imperfection sensitivity with respect to the governing buckling mode is examined.

Abstract:
This project conducted field optimization and long term testing on a typical Two Stroke Cycle (2SC) Lean bum pipeline engine to assess the feasibility of cylinder level diagnostics, air/fuel ratio balancing and air/fuel ratio control using ion sensing. Compare the performance with current and potential in-cylinder pressure based methods.

Abstract:
The ultimate goal of this work is to improve the current control methods for large bore, lean burn natural gas engines in order to combat performance and emissions issues during variable fuel composition events. This will be achieved in the long term by simulating the effects of variable fuel composition on a large bore, natural gas engine and developing engine control strategies which work to mitigate adverse effects. The work of Phase IV adds onto previous work by enabling the prediction of NOxemissions in the validated, full-scale engine simulation of a Cooper-Bessemer GMWH-10C developed in

Abstract:
In 2001, the Compressor and Pump Station Technical Committee (CAPSTC) recognized the importance of cylinder level sensing and control to minimize NOx emissions while maintaining optimum engine performance, therefore, a CAPSTC member brought the concept of ion sense to the committee as an alternative to fiber optic pressure sensors for continuous combustion performance monitoring. Derived from automotive technology, ion sense utilizes post ignition ionization measurements from a standard spark plug to monitor the combustions process.

Abstract:
The objective for this research was to conduct field-testing of typical Non Selective Catalytic Reduction (NSCR) Fitted Rich Burn pipeline engines to assess the feasibility of utilizing Ion Sense for cylinder level combustion diagnostics, load balancing and air fuel ratio indications. Sufficiently define the potential benefits of lon Sense in this application so that third party manufacturers and/or other funding agencies will consider further development and commercialization.
