Fluid Flow Structures in Staggered Banks of Cylinders Located in a Channel
(The American Society of Mechanical Engineers (ASME), 1995)This paper contains numerical experiments that model fluid flow through a staggered array of cylinders and represents a continuation of work previously performed by the authors (Braun et al., ... -
Effects of Initial Acceleration on the Flow Field Development Around Rapidly Pitching Airfoils
(The American Society of Mechanical Engineers (ASME), 1995)Computational results are presented to show how the acceleration period at the start of nominally constant pitch rate trajectories affects the dynamic stall process. Large amplitude motions of ... -
Experimental and Numerical Investigation of Flow Oscillations in a Rectangular Cavity
(The American Society of Mechanical Engineers (ASME), 1995)The unsteady, incompressible, moderate Reynolds number flow past a rectangular cavity is experimentally and numerically investigated. Laser-Doppler anemometry, flow visualization and unsteady numerical ... -
Mixing of a Generalized Newtonian Fluid in a Cavity
(The American Society of Mechanical Engineers (ASME), 1995)Mixing of a generalized Newtonian fluid in a corotating discontinuous cavity flow is studied. The flow period and the rheological coefficients are used as parameters. Using geometrical construction ... -
Separating and Reattaching Flow Structure in a Suddenly Expanding Rectangular Duct
(The American Society of Mechanical Engineers (ASME), 1995)The incompressible turbulent flow over a backward-facing step in a rectangular duct was investigated experimentally. The side wall effects on the core flow were determined by varying the aspect ... -
Relationship Between Unsteady Flow, Pressure Fluctuations, and Noise in a Centrifugal Pump—Part A: Use of PDV Data to Compute the Pressure Field
(The American Society of Mechanical Engineers (ASME), 1995)Velocity distributions determined by using Particle Displacement Velocimetry are used for computing the pressure field within the volute of a centrifugal pump. It is shown that blade-tongue ... -
