Review of Relevant Experiences

Space Turbomachinery Semiconductor Automotive BioMedical Fuel Cells

Various Fields - Two

Commonalities

• Combination of hands-on approach to engineering

and testing with analytical tools for analysis, design

and measurements

semiconductor, aeropropulsion, biomed,

space systems, automotive, energy

• Complex multi-physics systems based on

interactions of fluids with other media and physical

fields (electrical, chemical, magnetic, structural,

thermal) in steady state and dynamic situations
