Seeking a challenging position in mechanical engineering utilizing knowledge in computational fluid dynamics, stress analysis, and heat transfer.
2004 to 2010 CFD Research Corporation, Huntsville, AL
Applications Engineer, Aeromechanics Branch
• Served as senior support engineer for NASA MSFC in developing CFD models for Low-Orbit Debris Transport analysis for the Space Shuttle. Involvement in projects included geometry/grid generation, solver execution for attainment of multiphysics solutions, post-processing, and data visualization.
• Performed geometry/grid generation for SSME and Launch Pad structures for NASA MSFC using the OVERFLOW flow solver. Fieldview was used for post-processing and all results were documented.
• Developed the three-dimensional close proximity ARES Launch Abort Vehicle (LAV) computational model. I generated the geometry and grid for several configurations of the LAV. I also performed post-processing tasks and documentation.
• Developed the detailed (including protuberances) ARES Crew Launch Vehicle model for roll characteristics analysis. This major effort involved geometry/grid generation of the exterior flight control hardware.
• Performed geometry/grid generation of an integrated inflatable ballute for planetary atmospheric entry. The hypersonic atmospheric entry of the ballute required modeling of the stress management of the internal toroidal substructures which revealed solver inadequacies, the correction of which proved paramount for continued obtainment of funding. I afforded the solution of these problems.
• Performed Fluid/Structure Interaction Analysis (FSI) of the AGARD wing model and Delta Wing model using the CFD-ACE Solver. This required geometry/grid generation, model setup, solution generation, post-processing, and documentation of these efforts. The objective was to compare the solutions with empirical data related to mode shapes, flutter frequencies, and dynamic phase transitions.
• Perfected grid modifications for Large Eddy Simulations (LES) solutions of chemically reacting flow fields (Complex Combustion Simulations). Problems associated to the LES subroutine indicated formulation of key coding components were required. Wall Model reconstruction continued. The grid analysis made the code viable.
• Performed fluid flow/heat transfer analysis of the Flexible Engine Diagnostics System Dynamometer. I was responsible for geometry/grid generation, solver execution for attainment of multiphysics solutions, post-processing, data visualization, and documentation..
2000 to 2004 CFD Research Corporation; Huntsville, AL
Software Support Engineer
• Main responsibilities included customer problem management tasks and implementation of software development input protocol.
• Have prepared 124 tutorials that demonstrate grid generation techniques and procedures for numerous clients.
• Have developed advanced techniques for extending CFD-GEOM’s (CFDRC’s most effective Geometry/Grid generation tool) capabilities which mimic advancing layers capabilities for prismatic grid generation between arbitrarily shaped surfaces.
• Responsible for helping the Fluids Group at CATERPILLAR with cavitation models. This includes overcoming convergence problems due to cavitation settings and grid issues. The success of this support was instrumental in the group’s continued use of CFDRC’s products.
• Responsible for CFD-GEOM release notes verification/validation as well as monthly reviews of the ACE (CFDRC’s main flow solver) modules documentation. Conducted monthly training classes and performed tasks associated with improving the clients ability to utilize CFDRC’s tools effectively and efficiently. This includes extensive one-on-one training in model development for clients attending training each month.
1998 to 2000 SY Technology, Inc; Huntsville, AL
CFD Applications Engineer
• Worked on the Sapphire Statistical Characterization and Risk Reduction (SSCARR) program where I was responsible for maintaining the database for the sapphire test bars.
• Developed software for the Hypersonic Blunt Body problem used to predict convective heat transfer to the sapphire windows mounted on missiles.
• Performed CFD simulations for Tunnel 9 Aero-Optics Instrumentation Development Project using GASP.
1996 to1998 Adaptive Research; Huntsville, AL
CFD Applications Engineer
• Served as CFD Applications Engineer as head of support where my chief responsibilities were technical support in the areas of sales, development, and engineering contracts.
• Support of the software development consisted of organizing, documenting, participating in the software testing of new releases of CFD2000, a pressure based code (based on a variation of the PISO algorithm).
• My responsibilities in Engineering support consisted of performing analysis of flow fields related to contract work and documentation of such efforts.
• Additional responsibilities included conducting CFD2000 training classes and the development of the training manuals.
1995 to1996 Adaptive Research; Huntsville, AL
Code Development Consultant
• Worked as a consultant in the development of software performing a complete ramjet cycle analysis of hypersonic vehicles. This code combines elements from unstructured Euler solution methodologies in CFD and a ramjet cycle analysis in two or three dimensions.
• Responsibilities included extensive modification of existing code to include unstructured adaptive grid capabilities for the two-dimensional option, development of the three-dimensional option for structured grids, and general debugging of existing code.
1989 to1991 Teledyne Brown Engineering, Space Programs Division; Huntsville, AL
• Performed classical stress analysis for equipment mounted in Spacelab, mainly using NASTRAN. Project experience includes integrating Finite Element Models (FEMs), provided by each experiment’s principal investigator into Spacelab Rack FEMs according to the designers configurations dictated by module constraints and structural/mechanical requirements.
• I was responsible for stress analysis of the Spacelab Racks and Payload support hardware with emphasis on the Experiment-to-Rack and Rack-to-Module interfaces, detailed Rack structural analysis, and Rack dynamic characteristics.
