Energy Sources, Part A: Recovery, Utilization, and Environmental Effects
In this study, the effects of various absorber configurations of a tubular solar air heater are investigated. The models such as direct flow with a standard absorber (DF-SA), swirl flow with a standard absorber (SF-SA), swirl flow with perforated ...

Flow Phenomena in Swirl Chambers
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 1997Results are presented from two different swirl chambers. One of the practical directions for this study is simulation of cooling passages located near the leading edges of turbine blades where screw-shaped, swirling flows are generated to enhance heat transfer.

Engineering Computations, 1986
A mathematical model has been developed to study incompressible, isothermal, turbulent, confined, swirling flows. The model solves the conservation equations of mass, momentum, and two additional equations for the turbulent kinetic energy and the rate of dissipation of turbulent kinetic energy. The numerical predictions show a recirculation zone in the

Swirling flow between rotating plates
Archive for Rational Mechanics and Analysis, 1984The authors seek the solutions of the Navier Stokes equations in the form: \[ U_ x=xH'(z)-G(z)y+g(z);\quad \] \[ U_ y=yH'(z)+G(z)x- f(z);\quad U_ z=-H(z) \] and showed that H(z), G(z), g(z), f(z) satisfy a boundary value problem which constitutes the nonlinear von Kármán equations for axially symmetric swirling flow for functions H(z,\(\epsilon)\), G(z,

Calculation of confined swirling flows
23rd Aerospace Sciences Meeting, 1985Swirling jets are an important constituent flow of many types of combustion equipment. Flame size, shape, stability and combustion intensity are all favorably influenced by swirling some portion of the incoming air with the fuel. Fluid dynamics computer codes are being developed for the mathematical simulation of flows in practical combustors.

Abstract The problem of the decay of a rotationally symmetric steady swirl superimposed on Poiseuille flow in a round pipe was investigated theoretically and experimentally. The object was to determine the degree to which the rate of decay of the swirl as predicted by a linearized theory agreed with measured rates of decay at flow ...

Experiments on swirling turbulent flows. Part 1. Similarity in swirling flows
Journal of Fluid Mechanics, 1973The effects of swirl on internal turbulent flows are studied by conducting experiments on turbulent pipe flow with variable initial swirl. This first part of the study is primarily concerned with similarity laws. The mean velocity profiles, both away from and close to the wall, are found to admit similarity representations at sufficiently large ...
