OBJECTIVE:	A position of R&D Design Engineer.
SUMMARY:	Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), 3D CAD

WORK EXPERIENCE:

1995-Present

MEGTEC Systems, De Pere, WI, USA.

R&D Research Associate.

Responsible for technical analysis of heat exchangers, combustion equipment, air mixing devices, air dampers and other custom air handling equipment utilizing Computational Fluid Dynamics software, Finite Element Analysis Software as well as through utilization of materials engineering knowledge.

Interpreted experiment results and prepared associated documentation and reports.

Researched and filed patents and performed technical searches. Performed hardware setup and maintenance relating to Windows NT PC, UNIX workstations and networking.

FEA models include thermal and structural stresses analysis in both linear and nonlinear deformation range.

CFD simulation used both steady and transient turbulent flows with heat transfer, moving walls, multiple reference frames. Structured and unstructured meshes up to 1,600,000 cells were solved with temperature dependent flow properties, chemical mixing and reactions including combustion.

Following equipment was analyzed:

Regenerative Thermal Oxidizers 7,000 - 100,000 Nm³/hr were simulated for flow and temperature distribution, thermal and structural stresses.

Valves designs were evaluated for pressure drop, thermal and mechanical stresses. Number of mixing chambers (1150°K) was optimized for temperature gradient of mixed gases.

Combustion in low emission swirl burner (1400 kW) were simulated. Moving mechanism for this burner was designed.

Recuperative Thermal Oxidizer 14,000 Nm³/hr flow modeled to visualize flow in the combustion chamber. Tube sheet of tube and shell heat exchanger was modeled to evaluate thermal stresses.

Flow in 48,000 Nm³/hr Catalytic Oxidizer was optimized for a shorter gas line burner and lower temperature distribution on catalytic beds.

Components of Industrial Dryers (9 to 15 meter long) such as air-bars, airfoils, headers, fans, dampers, and burner chamber were analyzed and optimized with both CFD and FEA software. Paper web deflection in the dryer was modeled.
