CFD Applications/Support Engineer & Documentation Specialist

I served as Support Engineer involving technical support for clients using PumpLinx, Simerics MP, Simerics-PD, Simerics-Turbo, and Simerics-Valves. These CFD analysis tools provide accurate virtual testing for the analysis and performance prediction of fluid pumps, motors, compressors, turbines, valves, and complete fluid systems with rotating/sliding components. My responsibilities included training clients how to make effective use of Simerics Inc. products for the attainment of accurate and reliable CFD solutions and educating clients about best CFD practices.

Performed as Principle Technical Documentation Specialist where my responsibilities are to write technical manuals and tutorials for the many modules and templates comprising all Simerics Inc. CFD virtual testing tools.

I have performed FEA/CFD analysis requiring in depth knowledge of statics, dynamics, strength of materials, fluid mechanics, and heat transfer for the following devices: Screw & Scroll Compressors, Piston Pumps, Rolling Piston Pumps, Centrifugal & Axial Pumps, Relief Valves (Spool, Ball, Flip), Automatic Transmission Components, Aerospace LOX Turbopumps, Diesel Fuel Injectors, Propellers, Orifice Flows, Turbines, and Motors. The following are instructional videos that I produced while working for Simerics Inc. showing some of the simulations I generated:

08/2004 to 10/2010: CFD Research Corporation, Huntsville, AL

CFD/Multiphysics 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. This includes geometry/grid generation, solver execution for attainment of Multiphysics solutions, post-processing, and data visualization.

Performed geometry/grid generation for the 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 determination of roll characteristics. This 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 to these problems.

Performed Fluid/Structure Interaction (FSI) analysis for the AGARD Wing model and Delta Wing using the CFD-ACE+ solver. This required geometry/grid generation, model setup, post-processing, and documentation of these efforts. The objective was to compare the CFD 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) CCS. Problems associated with the LES module indicated reformulation key coding components were required. Wall Model reconstruction continued. The grid analysis I performed made the code viable.

Performed fluid flow/heat transfer analysis for the Flexible Engine Diagnostics System Dynamometer. I was responsible for geometry/grid generation, post-processing, and solver execution for attainment of multiphysics solutions, post-processing, data visualization, and documentation.

04/2000 to 08/2004: CFD Research Corporation, Huntsville, AL

CFD/Multiphysics Software Support Engineer, Software Support Branch

Main responsibilities included customer problem management tasks and implementation of software development input protocol.

Have developed advanced techniques for extending CFD-GEOM’s (CFDRC’s primary geometry/grid generation tool) capabilities to mimic advancing grid layers to better resolve Boundary Layers used for prismatic grid generation between arbitrarily shaped surfaces.

Responsible for helping many clients such as the Fluids Group at CATEPILLAR with implementation of cavitation models. This included 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.
