Theoretical and Experimental Study on Fully-Developed Compartment Fires
… and crib fires. The focus on the study is on the fully-developed fires where all available fuel becomes involved to the maximum extent and can potentially yield the severest damage to the structural elements. A single-zone compartment fire model is developed along with a fuel mass loss rate model …

Large Eddy Simulation Based Turbulent Flow-induced Vibration of Fully Developed Pipe Flow
Flow-induced vibration caused by fully developed pipe flow has been recognized, but not fully investigated under turbulent conditions. This thesis focuses on the development of a numerical Fluid-Structure Interaction (FSI) model that will help define the relationship between pipe wall vibration and …

Pressure drop in fully developed, turbulent, liquid-vapor duct flows at zero gravity
… of the frictional pressure drop in steady, fully developed, turbulent liquid-vapor duct flows in both dispersed and annular flow regimes. The dynamics of such flows are simulated by using two immiscible, neutrally buoyant liquids, water and n-butyl benzoate, in an earth based flow facility.

Laser doppler anemometer measurements of Reynolds stresses in a fully developed pipe flow
… used to make Reynolds stress measurements in a fully developed, turbulent pipe flow. Traverses are made to measure shear stress, normal stresses, and the correlation coefficient. To assess the accuracy of this system, these measurements are compared with results from other published …

Numerical Study of Fully Developed Laminar and Turbulent Flow Through Microchannels with Longitudinal Microstructures
… reports the numerical study of hydrodynamically fully-developed laminar and turbulent flows through a parallel plate channel with walls exhibiting micro-ribs and cavities oriented parallel to the flow direction, where fully developed turbulent flow is considered in a time-averaged sense. Three …

A direct numerical simulation of fully developed turbulent channel flow with passive heat transfer
A direct numerical simulation of a fully developed turbulent channel flow with passive heat transfer is performed. The time-dependent three-dimensional Navier-Stokes equations and advection-diffusion equation are solved numerically using a pseudospectral technique with 1,064,960 grid points in …

An experimental study of the effect of small particles on the fluid turbulence in fully developed flow of air in a horizontal pipe
Measurements of the mean and fluctuating velocities of both the solid and gas phases in a dilute suspension flowing through a 5 in diameter horizontal pipe are presented. Velocity measurements for both phases were obtained using Laser Doppler Velocimetry; signal discrimination was accomplished …

An experimental investigation of the turbulent flow in a closed compound channel
… laser Doppler anemometer was used to measure the fully developed, turbulent flow in a closed, symmetric, smooth-wall compound channel. Measurements were made across one quadrant of the cross-section since the flow was assumed symmetric. Measurements were made for a single channel Reynolds number. …

An experimental investigation of interacting wing-tip vortex pairs
… cores. Flow in the vicinity of the cores appears fully developed. During the merging process, the cores rotate rapidly about each other, winding the wing wakes into a fine spiral structure. Merger roughly doubles the core size and appears to produce turbulence over abroad range of frequencies. The …

Atomization and Deposition in Two-Phase Annular Flow: Measurement and Modeling (Pressure Drop, Thin Films, Turbulent Dispersion)
Models have been developed for the rate processes of atomization from the wall layer in vertical annular two-phase flow and of deposition of this liquid back to the liquid film. These models have been incorporated into a design scheme for the prediction of two-phase pressure drop and fully …
