  • Heat transfer during the piston-cylinder expansion of a gas

    Creator:
    Rodrigues, Matthew Jose
    Abstract:
    The expansion of a gas within a piston-cylinder arrangement is studied in order to obtain a better understanding of the heat transfer which occurs during this process. While the situation of heat transfer during the expansion of a gas has received considerable attention, the process is still not very well...

  • Effects of orifice geometry and surface boundary condition on heat transfer of impinging jet array

    Creator:
    Kanokjaruvijit, Koonlaya.
    Abstract:
    The effects of the orifice geometry and the surface boundary condition on the heat transfer distribution to a flat surface of an impinging jet array were investigated. The jet array impinged normally onto the surface which was either isothermal or had a uniform heat flux. The experiments were performed for...

  • Flow characteristics of semi-confined impinging jet arrays

    Creator:
    Dano, Bertrand P. E.
    Abstract:
    The present study proposes to investigate the flow structure of different arrays of jets impinging on a flat surface enclosed by three walls, creating a channel that forces the air to leave in one preferential direction, generating a self sustain crossflow. Details of both the mean and some turbulence quantities...

  • Study of creeping, inertial and turbulent flow regimes in porous media using particle image velocimetry

    Creator:
    Patil, Vishal A.
    Abstract:
    Porous media flows are encountered in many natural and man-made systems such as gas adsorption, filtration, heat exchangers, combustion, catalytic reactors and groundwater hydrology. This study experimentally investigates these flows as function of pore Reynolds number, Re[subscript pore]. The pore Reynolds number is based on the porous bed hydraulic diameter,...

  • A study of the characteristics of oscillatory surface instabilities leading to droplet formation

    Creator:
    Daniels, Brian J.
    Abstract:
    The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...

  • The effects of pulsing and blowing ratio on a 45° inclined jet in cross flow

    Creator:
    Stander, Arjan
    Abstract:
    The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...

  • Investigations into the effects of a vibrating meniscus on the characteristics of drop formation

    Creator:
    Lewis, Kevin T.
    Abstract:
    As drop-on-demand (DOD) applications continue to gain ground in desktop inkjet-printing, 3D printing, fluid mixing, and other areas the demand for higher frequency operations are beginning to push against the current physical boundaries in DOD technology. The current research is exploring the possibility of controlling drop volume and velocity at...

  • Simulation of drag reduction due to multi-aligned spheres

    Creator:
    Lindqvist, Varna
    Abstract:
    A method was sought to predict the flight paths and collisions for closely spaced ink droplets of various sizes as a design aid for ink-jet printing development. Computational fluid dynamics models of two rigid aligned spheres, as a proxy for ink droplets, were initiated in atmospheric pressure air at constant...

  • Characterization of flow boiling in a fractal–like branching microchannel network

    Creator:
    Edward, Lee M.
    Abstract:
    Based on experimental investigations the present study evaluates flow instability and void fraction in a fractal-like branching microchannel network with rectangular cross-section. The hydraulic diameter of the channels ranged from 308μm at the inlet to 143μm at the outlet. The flow network used is characterized by set branching ratios for...

  • Interactions of a fully modulated inclined jet with a crossflow

    Creator:
    Dano, Bertrand P. E.
    Abstract:
    Jets in crossflow are used in a wide range of engineering applications and have been studied for more than 60 years. The transversal penetration and structure of a jet placed in a crossflow is known to be strongly three-dimensional. It is believed that, by using a pulsed jet inclined in...
