This book was released on 1972 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solutions are developed for a one dimensional compressible gas bubble-liquid mixture flow through a converging-diverging nozzle. Gas is assumed in the form of spherical bubbles that do not exchange mass with the liquid, but allowance is made for a differential between bubble and liquid velocities. The critical condition for the specified initial flow conditions is found by iteration to establish the local slope of the nozzle wall at each step near the throat, and thus the critical throat is designed uniquely for each flow. Assuming adiabatic expansion for the air bubbles critical and supercritical solutions are obtained for a few specified initial conditions. A choking condition is noted at the section just upstream of the geometric throat of the nozzle. (Author).

This book was released on 1963 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research concerns the experimental and theoretical studies of the flow of a predominantly liquid two-phase fluid in nozzles and diffusers, undertaken as part of a longrange program dealing with the development of a gas-driven jet pumpt for rocket engines. The physical description of the flow is based on momentum, heat, and mass transfer phenomena, droplet mechanics, and the influence of flow geometry and operating conditions. As the mass ratio of one of the components is increased, it is imperative to consider at least some aspects of the discreteness of the component of lower volume in mass and energy transfer processes in a theoretical analysis for a first-order prediction of velocities, droplet diameters, and pressure for the flow in an accelerating or nozzle flow and a decelerating or diffuser flow. In the nozzle experiments, the total flow rate and the mass ratio of liquid to gas were varied to establish a series of design and performance parameters. The experimental investigation for diffusing flows was performed employing a conical diffuser and a predominantly liquid medium with the gas in the form of small bubbles dispersed in the liquid. The objects of the research were to determine the feasibility of diffusing a free jet to liquid and the effect of gas entrained in the flowing liquid. (Author).

Download or read book An Experimental Investigation of Two phase Two component Flow in a Horizontal Converging diverging Nozzle written by Joseph A. Vogrin and published by . This book was released on 1963 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion is presented of an investigation of the flow characteristics in a horizontal, converging-diverging nozzle for a two-phase, air- water system. The primary consideration, to determine the effects of accelerating the liquid phase by the gaseous phase, was measured in terms of nozzle exit water velocity, exit slip ratio, and exit acceleration factor. A gamma-ray-attenuation technique was used to determine these values by determining the average cross-sectional void fraction, the ratio of gas volume to total volume, for the air-water mixture.

This book was released on 1962 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical method is presented for determining the flow characteristics of a two-phase flow of liquid drops in a gas stream as the mixture expands through an annular converging-diverging nozzle. The subject analysis can be utilized to predict the liquid velocity, gas velocity, static pressure, and droplet diameter as a function of AXIAL DISTANCE ALONG THE NOZZLE FOR A TWO-PHASE FLOW THAT CONTAINS APPROXIMATELY 10 TIMES AS MUCH LIQUID AS GAS BY WEIGHT. Two nozzle configurations were investigated. Both had the same converging angle of 20 degrees, throat radius of 1 in., inlet area of 3.287 sq. in., throat area of 0.267 sq. in. and exit area of 2.450 sq. in. One nozzle had a total diverging angle of 7 degrees and the other had a total diverging angle of 21 degrees. Flow rates of between 8 and 11 lb/sec of water and between 1.0 and 1.3 lb/sec of air were utilized. The liquid and gas were expanded from a low velocity and a pressure of 500 psig to ambient pressure. The theoretical and experimental pressure profiles matched closely for both nozzles investigated. The thrust was predicted to an accuracy of approximately 3% for the short nozzle, but to an accuracy of only approximately 20% for the long nozzle.
