Turbulent Characteristics in Stirring Vessels: A Numerical Investigation
(Virginia Tech, 2006-06-16)
Understanding the flow in stirred vessels can be useful for a wide number of industrial applications, like in mining, chemical and pharmaceutical processes. Remodeling and redesigning these processes may have a significant ...
Large Eddy Simulation of Flow and Heat Transfer in a Staggered 45° Ribbed Duct and a Rotating 90° Ribbed Duct
(Virginia Tech, 2003-11-24)
For the past several years there has been great effort in the analysis of internal duct cooling. The steady increase in power output and thermal efficiency requirements for gas turbine engines has called for significant ...
Flow Field Computations of Combustor-Turbine Interactions in a Gas Turbine Engine
(Virginia Tech, 2001-02-07)
The current demands for higher performance in gas turbine engines can be reached by raising combustion temperatures to increase thermal efficiency. Hot combustion temperatures create a harsh environment which leads to the ...
An Analysis of Using CFD in Conceptual Aircraft Design
(Virginia Tech, 2002-05-27)
The evaluation of how Computational Fluid Dynamics (CFD) package may be incorporated into a conceptual design method is performed. The repeatability of the CFD solution as well as the accuracy of the calculated aerodynamic ...
Simulation of Airflow and Heat Transfer in Buildings
(Virginia Tech, 2009-10-30)
Energy usage in buildings has become a major topic of research in the past decade, driven by the increased cost of energy. Designing buildings to use less energy has become more important, and the ability to analyze ...
Liquid Sodium Stratication Prediction and Simulation in a Two-Dimensional Slice
(Virginia Tech, 2017-03-28)
In light of rising global temperatures and energy needs, nuclear power is uniquely positioned to offer carbon-free and reliable electricity. In many markets, nuclear power faces strong headwinds due to competition with ...
Using Simulink to Develop a One-Dimensional, Two-Phase Fluid Model
(Virginia Tech, 2014-02-04)
In this thesis, a one-dimensional, two-fluid model is developed in MATLAB-Simulink. The model features a mass, momentum, and energy balance for each fluid--an ideal gas and an incompressible liquid. The simulation may ...
Investigation of suction recirculation in rocket pump inducers
(Virginia Tech, 1996)
Tools and Techniques for Flow Characterization in the Development of Load Leveling Valves for Heavy Truck Application
(Virginia Tech, 2018-06-04)
This research examines different techniques and proposes a Computational Fluid Dynamics (CFD) model as a robust tool for flow characterization of load leveling valves. The load leveling valve is a critical component of an ...
Computational study of hub corner stall in an axial compressor rotor
(Virginia Tech, 1995-08-15)
<p>The Deverson rotor, a single stage axial compressor designed to simulate a multistage axial compressor, was studied computationally using a 3-D Navier-Stokes solver, the Moore Elliptic Flow Program. A one equation, q-L, ...
