Use of Subdomains for Inverse Problems in Branching Flow Passages
(The American Society of Mechanical Engineers (ASME), 1993)For inverse problems in complex flow passages, a calculation procedure based on a multizone Navier-Stokes method was developed. A heuristic approach was employed to derive wall shape corrections ... -
Capillary Instability of a Jet of Liquid Metal
(The American Society of Mechanical Engineers (ASME), 1993)A system based on ink-jet technology has been used to demonstrate the controlled generation of monodispersed 100 μm diameter molten solder droplets. Oxide formation on the surface of the molten ... -
One-Equation Near-Wall Turbulence Modeling With the Aid of Direct Simulation Data
(The American Society of Mechanical Engineers (ASME), 1993)The length scales appearing in the relations for the eddy viscosity and dissipation rate in one-equation models were evaluated from direct numerical (DNS) simulation data for developed channel ... -
Added Mass Coefficients for Submerged Bodies by a Low-Order Panel Method
(The American Society of Mechanical Engineers (ASME), 1993)The added mass coefficients for two and three-dimensional submerged bodies were calculated using a low-order panel code. The source and dipole strengths, and the panel surface area for each ... -
Experimental Observations of Flow Instability in a Helical Coil (Data Bank Contribution)
(The American Society of Mechanical Engineers (ASME), 1993)Experimental observations were made for the nominally fully developed flow through a helically coiled pipe of circular cross-section with a curvature radius to pipe radius ratio Rc /a = 18.2. ... -
Turbulent Swirling Flow in Short Cylindrical Chambers
(The American Society of Mechanical Engineers (ASME), 1993)Turbulent swirling flow in a short closed cylindrical chamber has been measured with laser Doppler anemometry. The swirl was generated by a rotating roughened disk and measured during steady ... -
Prediction of Three-Dimensional Steady Incompressible Flows Using Body-Fitted Coordinates
(The American Society of Mechanical Engineers (ASME), 1993)A finite-volume method for three-dimensional, steady, incompressible flows in complex geometries is presented. The method uses generalized Body-Fitted Coordinates to accurately take into account the ... -
Study of Nuclei Distribution and Vortex Diffusion Influence on Nuclei Capture by a Tip Vortex and Nuclei Capture Noise
(The American Society of Mechanical Engineers (ASME), 1993)Earlier studies of cavitation nuclei behavior in the presence of a Rankine tip vortex have shown that the nuclei is attracted or captured by the vortex pressure field and during this process ... -
Interpretation of Impeller Flow Calculations
(The American Society of Mechanical Engineers (ASME), 1993)Most available computer programs are analysis and not design programs. Therefore the intervention of the designer is indispensable. Guidelines are needed to evaluate the degree of fluid mechanic ... -
A Comparison of Four Velocity Bias Correction Techniques in Laser Doppler Velocimetry
(The American Society of Mechanical Engineers (ASME), 1993)Data from a two-component dual-beam laser-Doppler Velocimeter were used to evaluate four different velocity bias correction methods. The data were collected over a range of valid data rates from ... -
Turbulent Flows in a Model SDR Combustor
(The American Society of Mechanical Engineers (ASME), 1993)An experimental study is reported on the isothermal flow fields in a model solid-propellant ducted rocket combustor with two opposing side inlets. The measurements were made by using a four-beam ... -
Holographic Visualization of Convective Flow Around a Heated Rotating Cone of Finite Length
(The American Society of Mechanical Engineers (ASME), 1993)The convective flow around a heated rotating cone of finite length is investigated experimentally by means of 3-D and real-time holographic interferometry at rotational speeds of up to 4600 rpm ... -
Simulation of the Nonreacting Flow in a Bluff-Body Burner; Effect of the Diameter Ratio
(The American Society of Mechanical Engineers (ASME), 1993)Axisymmetric vortex simulation is used to study the unsteady dynamics of the flowfield generated by the interaction between two concentric jets initially separated by a thick bluff-body. The ... -
