Embry Riddle Aeronautical University
Dr. Attia spent 9 years as a senior engineer working for Westinghouse Electric and Siemens Westinghouse Power first in the advanced engine development group, then in the compressor group, and later in the design systems and methods group. His research focuses on the aerodynamics and thermodynamics of axial compressors and turbines for industrial applications. Areas of particular interest are design systems, aerodynamics of highly loaded components, and cycle thermodynamics. Dr. Attia has multiple publications in the field as well as one patent, he is also active in consulting for industry.
Dr. Eric Perrell - Dr. Perrell expertise is in CFD, especially for combustion applications. His current areas of research include CFD development, parallel computing, and multi-species non-equilibrium CFD.
Dr. David Sypeck - Dr. Sypeck's research deals with cellular solids - interconnected networks of solid struts or plates that join to form the edges and faces of cells. Polymers, ceramics, glasses, metals and composites can be fabricated into a cellular structure. These types of materials find application as impact energy absorbers and cores of composite structural panels. Imitating decades of work by structural engineers, cellular metals are now being fabricated as miniature open cell lattices (trusses) constructed from wrought steel (or other alloy) struts precisely arranged at the cell level. The open interconnected porosity within cells provides opportunity for a variety of matrix materials (e.g., air, coolant, polymer foam, etc.) and multifunctional possibilities. With this research, efficient truss-like architectures are identified, fabrication by affordable textile and sheet lamination methods are pursued with properties validation through experiment.
Dr. Hany Nakhla - Dr. Nakhla worked in the consulting field prior to joining Embry Riddle University . His expertise is in general CFD for large volumes and complex geometries. In the past, he worked on problems such as heat exchangers with conjugate heat transfer issues, axial and radial fan performance, inlet systems with droplet tracking (fogging), exhaust gas treatment with multi-species, and turbine blade cooling.
Dr. Vladimir Golubev - Dr. Golubev spent 3 years as a CFD specialist for the Trane Company in the field of numerical and experimental investigations of rotating instability in multi-stage centrifugal compressors. His current areas of research include steady and unsteady CFD of ultra quiet axial fan, noise prediction and control, and multi-disciplinary optimization (MDO) analysis tools. Dr. Golubev is currently working with NASA-Glenn to develop high order aero-acoustic CFD tools. Dr. Golubev has a number of publications in the field.
Dr. Eric Hill - Dr. Hill is involved in research dealing with NDE for structures and instrumentation. In particular he is interested in acoustic emissions for predicting and detecting cracks and crack propagation, and the use of neural networks to manage and interpret acoustic data for real time detection of cracks.
In terms of applicable facilities, ERAU has the following:
• A large UNIX-based supercomputer (NSF funds approved, system is anticipated to be operational by spring of 2005)
• Two fully functioning gas turbine engine test cells along with several turbojet (J34) and turbo shaft (T53) engines. The test cells are actively used for instructional purposes. The existing instrumentation serves to monitor the overall engine performance. The instrumentation can be appropriately modified to suit any research needs.
• Several small LINUX clusters (6-, 8-, and 16-node) for parallel computing
• Full licenses of the most widely used commercial software such as CFX, Fluent, Star-CD, Pro-E, and CATIA, as well as visualization software.
• Four wind tunnels for various applications
• Structures and Instrumentation Lab and composites Lab.
