Design And Numerical Simulation Of Two Dimensional Ultra Compact Combustor Model Sections For Experimental Observation Of Cavity-Vane Flow Interactions, David S. Moenter
Design And Numerical Simulation Of Two Dimensional Ultra Compact Combustor Model Sections For Experimental Observation Of Cavity-Vane Flow Interactions, David S. Moenter
Theses and Dissertations
An improved computational fluid dynamics (CFD) model was developed for numerical simulation of the Ultra Compact Combustor (UCC) concept to enhance turbulent flow characterization of the circumferentially traveling, centrifugal-force enhanced combustion, cavity flow into the engine main flow passage via a radial cavity in the turbine axial guide vanes. The CFD model uses a dense grid on a 60° periodic, axisymmetric combustor section, with the RNG κ-ε turbulence model to resolve turbulent flow details. An overall analysis and performance evaluation of the experimentally tested UCC configuration and an axially shortened cavity baseline configuration was conducted at various experimentally documented operating …
Application Of The Finite Element Method Using The Method Of Weighted Residuals To Two Dimensional Newtonian Steady Flow With Constant Fluid Properties, Mien Ray Chi
Theses and Dissertations
In this thesis we will be concerned with the two-dimensional steady laminar Newtonian fluid flow with constant fluid properties in Cartesian coordinate system. More precisely, we will consider a flow for which the interesting dependent variables, for example, velocity, vorticity, stream function, etc., are expressible as functions of two independent Cartesian coordinates.
Transition From Laminar To Turbulent Flow For A Two-Phase Mixture, Mohammed Sharief Qureshi
Transition From Laminar To Turbulent Flow For A Two-Phase Mixture, Mohammed Sharief Qureshi
Theses and Dissertations
A phase is simply one of the states of matter. Multiphase flow is the simultaneous flow of several phases. Two-phase flow is the simplest case of multiphase flow.
Developing Turbulent Flow In An Annulus, Dwight H. Kelly
Developing Turbulent Flow In An Annulus, Dwight H. Kelly
Theses and Dissertations
Turbulent flows are encountered in nearly every case where fluid motion is involved. Since turbulent flow through relatively short annular sections occurs frequently in practical applications, e.g., flow through heat exchangers, axial flow turbomachinery and jet aircraft engines, there is a need for detailed information on this subject.
The Development Of Turbulent Flow In The Inlet Region Of Smooth Pipe, Forrest C. Smith
The Development Of Turbulent Flow In The Inlet Region Of Smooth Pipe, Forrest C. Smith
Theses and Dissertations
Turbulent flows are encountered in nearly every case where fluid motion is involved. Turbulent flow in pipes is of great practical interest, and the problem of flow in the entry region is of special importance since the great majority of applications are in the realm of developing flow.
Turbulent Flow In The Entry Region, Chin-Hsiu Li
Turbulent Flow In The Entry Region, Chin-Hsiu Li
Theses and Dissertations
When entering into the subject of turbulent flow, it is essential to understand that the kind of flow with which we deal belongs to a particular class known as shear flow. These types of flow comprise flow fields in which relative velocities have been induced by shear stresses rather than by the action of pressure forces. In pipe flow, when the fluid enters through the well-rounded bell from a reservoir or from the calm open air, a uniform velocity distribution occurs at the pipe entrance. Immediately down stream from the entrance of the pipe, the flow is structured with a …
Liquid Particle Interaction With A Normal Shock Wave, Victor George Forsnes
Liquid Particle Interaction With A Normal Shock Wave, Victor George Forsnes
Theses and Dissertations
The atomization of a liquid by an air stream has been an item of much concern in the past, and there have been numerous experimental studies of the process made in an effort to correlate liquid and air- stream physical properties into a general model which will predict the degree of and the time required for atomization for a given physical situation. The breakup of liquid drops, a major portion of the atomization process, finds application in the field of meteorology, where the formation, breakup, and shape of raindrops is an item of much concern; in the field of internal …
