Available in PDF, EPUB and Kindle. Book excerpt: Worked Examples in Turbomachinery (Fluid Mechanics and Thermodynamics) is a publication designed to supplement the materials in Fluid Mechanics, Thermodynamics of Turbomachinery, Second Edition. The title provides detailed solution for the unanswered problems from the main textbook. The text first covers dimensional analysis, and then proceeds to tackling thermodynamics. Next, the selection discusses two-dimensional cascades. The text also talks about axial flow turbines and compressors, along with the three-dimensional flow in axial turbo machines. Chapter 7 covers centrifugal compressor and pumps, while Chapter 8 tackles radial flow turbines. The book will be of great use to students of mechanical engineering, particularly those who have access to the main textbook.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research has been the investigation of the nature of three-dimensional motion associated with the interaction between rotating axial flow blade rows and the working fluid, i. e. air, and the quantitative determination of the effect of three-dimensional motion upon the process of energy conversion. The investigation pertained to both the subsonic and the transonic regime of flow in turbomachines. It has been pursued by the theoretical as well as the experimental approach. Theoretical studies have been concerned with the analysis of compression shocks in regions of flow with an upstream total enthalpy gradient and with analogous patterns encountered in the flow relative to the blades of a rotating blade grid. Computations of the flow field behind threedimensional oblique shocks were carried through parallel to corresponding experimental studies.

This book was released on 1974 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general objective of the investigation reported in this thesis is to obtain a reliable understanding of the three dimensional potential flow through axial flow turbomachinery. The calculation of the three dimensional potential flow through an impeller is based on the method of distributed singularities. The blades are replaced by a series of line vortices and line sources which have their axes along the radial direction and are arranged along the blade camber surface. The basic perturbed velocity fields due to a single radial vortex line of constant strength and a single radial source line of variable strength along the radial direction are computed from a modified theory based on Tyson's and Rossow's formulation. Since the resultant perturbed flow fields are solutions of the linear Laplace equation and the boundary conditions are homogeneous, these solutions may be superimposed for a series of radial vortex lines and source lines located at arbitrary points. Eigen values and related functions are calculated for Bessel function of order m = 0 to 100, number of eigen values for each order of Bessel function n - 20, hub-to-tip ratio nu = 0.3, 0.6. A computer program to obtain the three dimensional flow field in a turbomachinery with arbitrary number of blades, number of singular points per blade, and singular points locations was developed. Examples illustrating the interference effects due to hub-to-tip ratio, stagger angle, numbers of the blades were carried out. The effects of the radial variation of the strength of the radial source line were examined. The three dimensional effects are found to be appreciable for low hub tip configuration with fewer number of blades. (Author).

This book was released on 1989 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: While strongly three dimensional and highly unsteady nature of the flow in axial turbines has, until recently, defied in-depth analysis, the benefits that can be realized from an improved capability to predict the aerodynamics and heat transfer in turbines are numerous. These benefits include improved performance through higher efficiency, higher thrust-to-weight ratio through higher turbine inlet temperature, and improved durability through more precise predictions of local heat load. This program was particularly interested in the aerodynamic mechanisms affecting attenuation of a radial temperature profile in the flow as it passed through the turbine. The radial temperature profile in the flow exiting a combustor and entering a turbine can range from compressor exit temperature (approx = 1100 F) near the hub and tip end walls to a maximum (as high as 3200 F) in the midspan region. The heat load at any location on the turbine airfoils or end walls depends strongly on the local gas temperature at that location; hence the mixing, or attenuation, of the inlet temperature profile is of critical importance. This program has advanced the state-of-the-art by providing: 1) an exhaustive aerodynamic data base for the three dimensional flow in a large scale axial turbine; 2) an exhaustive data base documenting the mixing of a simulated combustor exit temperature profile as it passed through the turbine; and 3) an assessment of sota three dimensional time accurate, Navier-Stokes prediction of the flow in the turbine stage. Keywords: Temperature redistribution. (EDC).

Book excerpt: This paper presents an exhaustive experimental documentation of the three-dimensional nature of the flow in a one-and-one-half stage axial turbine. The intent was to examine the flow within, and downstream of, both the stator and rotor airflow rows so as to delineate the dominant physical mechanisms. Part 1 of this paper presents the aerodynamic results including: (1) airflow and endwall surface flow visualization, (2) full-span airfoil pressure distributions, and (3) radial-circumferential distributions of the total and static pressures, and of the yaw and pitch angles in the flow. Part 2 of the paper presents results describing the mixing, or attenuation, of a simulated spanwise inlet temperature profile as it passed through the turbine. Although the flow in each airfoil row possessed a degree of three-dimensionality, that in the rotor was the strongest.
