  • Integrated forward light scattering as a measure of aerosol mass concentration

    Creator:
    Tomine, Chris Shinya
    Abstract:
    A mathematical model was developed that relates the ratio, R, of two light flux measurements to the mass concentration, m, of the atmospheric aerosol particles between a source of parallel light (e.g., the sun) and the measuring system. R is defined as the ratio of the light fluxes passing through...

  • Heat transfer in magnetic fluids at low Reynolds number

    Creator:
    Choi, Sang Hyouk
    Abstract:
    This study was concerned with the flow of a magnetic self-propelled ferrohydrodynamic fluid in a horizontal circular tube subjected to axially varying temperature and magnetic field. The first phase of the study involved the analytical solution to the governing equations for the velocity and temperature profiles within the fully developed...

  • Robust lateral pulse jet control of an atmospheric rocket

    Creator:
    Burchett, Bradley Thomas
    Abstract:
    Uncontrolled direct fire rockets exhibit high impact point dispersion, even at relatively short range, and as such have been employed as area weapons on the battlefield. In order to reduce the dispersion of a direct fire rocket, feedback control is employed to fire short-duration solid rocket pulses mounted near the...

  • Study of Energy Harvesting Performance of Oscillating Airfoils using a Discrete Vortex Model

    Creator:
    Kamrani Fard, Kiana
    Abstract:
    The energy harvesting performance of oscillating airfoils is studied using a discrete vortex model (DVM) with a leading-edge separation criterion. The airfoil undergoes a combined sinusoidal heaving and pitching motion at reduced frequencies of k = 0.06 − 0.16, with heaving amplitude of h0 = 0.5c, and pitching amplitude of...

  • Applications of the thermal wave technique in liquid thermal conductivity measurements and flow field diagnostics

    Creator:
    Wang, Zhefu
    Abstract:
    The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...

  • Drilling process evaluation by predicting drilled hole quality and drill bit wear with on-line acoustic emission signals

    Creator:
    Wang, Kuang-Jen, 1962-
    Abstract:
    Improvement of manufacturing productivity is dependent on the successful automation of manufacturing processes, the success of which is based in turn upon the availability of information which describes the state of manufacturing operations. Acoustic Emission (AE) signals related to the cutting process and tool wear have been recently applied to...

  • Response of guyed offshore towers to stochastic loads in the presence of steady current

    Creator:
    Brynjolfsson, Sigurdur
    Abstract:
    The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered....

  • Vibrations of suspended cables

    Creator:
    Gale, John Gregg
    Abstract:
    The equations of motion of an elastic cable suspended in a viscous medium from two arbitrary points are derived. These are then linearized for the undamped, inextensible case, and it is found that the equations describing the in-plane motion of the cable are then independent of the equation describing the...

  • An analytical model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed

    Creator:
    Adams, Ronald Lynn
    Abstract:
    A steady gas convection model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed is presented. Contributions due to flow within attached bubbles as well as the interstitial voids are included. The interstitial flow is approximated as flow within a series of double cusped channels and...

  • A relationship between wave dispersion and fracture strength for a composite material

    Creator:
    Ilcewicz, Larry Bert
    Abstract:
    Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...
