Finite element analysis of subregions using a specified boundary stiffness/force method
(Virginia Polytechnic Institute and State University, 1985)
A three-dimensional turbine engine analysis compressor code (TEACC) for steady-state inlet distortion
(Virginia Tech, 1996-12-15)
Modem high-performance military aircraft are subjected to rapid flight maneuvers which place great operational demands on their compression system by producing highly distorted flow to the compressor. Inlet distortion ...
Micropolar Continuum Modeling of Large Space Structures with Flexible Joints and Thermal Effects: Theory and Experiment
(Virginia Tech, 2008-01-30)
The presented work is intended to develop a geometrically reduced order (homogenized) model for a large antenna space structure with flexible joints. An energy equivalence concept is employed to find the continuum model ...
Numerical Analysis of Flow and Heat Transfer through a Lean Premixed Swirl Stabilized Combustor Nozzle
(Virginia Tech, 2017-04-11)
While the gas turbine research community is continuously pursuing development of higher cyclic efficiency designs by increasing the combustor firing temperatures and thermally resistant turbine vane / blade materials, a ...
Impact Damage Resistance of Shape Memory Alloy Hybrid Composite Structures
(Virginia Tech, 1998-05-26)
The strain energy absorption of shape memory alloy (SMA) bars and beams under tension and bending loading was studied. A theoretical model is presented that can give quantitative relations between the martensite fraction, ...
Non-linear finite element thermo-hydrodynamic analysis of oil ring seals used in high pressure centrifugal compressors
(Virginia Tech, 1995-08-09)
The analysis of oil seals is of great concern for the proper design of high pressure centrifugal compressors, because they can have significant influence on the dynamic stability of the compressor rotor. The lack of adequate ...
Molecular Structure and Dynamics of Novel Polymer Electrolytes Featuring Coulombic Liquids
(Virginia Tech, 2019-01-25)
Polymer electrolytes are indispensable in numerous electrochemical systems. Existing polymer electrolytes rarely meet all technical demands by their applications (e.g., high ionic conductivity and good mechanical strength), ...
Adaptive vibration absorber
(Virginia Tech, 1996)
A Detailed Study of Fan-Shaped Film-Cooling for a Nozzle Guide Vane for an Industrial Gas Turbine
(Virginia Tech, 2005-11-28)
The goal of a gas turbine engine designer is to reduce the amount of coolant used to cool the critical turbine surfaces, while at the same time extracting more benefit from the coolant flow that is used. Fan-shaped holes ...
