Novel turbomachinery concepts for highly integrated airframe/propulsion systems
- P. Shah
Two novel turbomachinery concepts are presented as enablers to advanced flight missions requiring integrated airframe/propulsion systems. The first concept is motivated by thermal management… Expand
Reconstruction of Far-Field Noise Using Multireference Acoustical Holography Measurements of High-Speed Jets
Aero-Acoustics of Drag Generating Swirling Exhaust Flows
Aircraft on approach in high-drag and high-lift configuration create unsteady flow structures which inherently generate noise. For devices such as flaps, spoilers and the undercarriage there is a… Expand
2-D Tank Sloshing Using the Coupled Eulerian- LaGrangian (CEL) Capability of Abaqus/Explicit
Tank sloshing has been a unique challenge in many civil, aerospace, and energy applications, and it can cause forces that are difficult to predict using traditional simulation techniques.… Expand
A High-Resolution, Continuous-Scan Acoustic Measurement Method for Turbofan Engine Applications
Detailed mapping of the sound field produced by a modern turbofan engine, with its multitude of overlapping noise sources, often requires a large number of microphones to properly resolve the… Expand
Corneal pathology in microphthalmia with linear skin defects syndrome.
PURPOSE To describe the histopathology of the cornea in microphthalmia with linear streaks (MLS) syndrome. METHODS Two patients with MLS syndrome underwent penetrating keratoplasty. This study… Expand
Insulin autoimmune syndrome as a cause of spontaneous hypoglycemia in alcoholic cirrhosis.
Hypoglycemia in fulminant hepatic failure and hyperinsulinemia in cirrhosis are well-described phenomena. A patient with alcoholic cirrhosis who developed fasting hypoglycemia with an extremely high… Expand
Axisymmetry and azimuthal modes in jet noise
This paper will show that the matrix of all noise spectra radiated from a jet in a stationary condition, axisymmetric in construction and boundary conditions, has a special invariant structure which… Expand
Turbulent transport in the core of a trailing half-delta-wing vortex
The development of a turbulent streamwise vortex core in the wake of a half delta wing has been examined using high-resolution DPIV. The objective of this work was to gain understanding of the… Expand
The viscous Fluid Mechanical Particle Barrier for the prevention of sample contamination on the Mars 2020 mission
Abstract The Mars 2020 mission will land a rover on the surface of Mars that will acquire, encapsulate, and cache scientifically selected samples of martian material for possible return to Earth by a… Expand
