Fluid Dynamics Eng - PAX Mixer - San Rafael, CA

Gary Jong

PAX Mixer Inc. (PMI) located in San Rafael (soon to be Napa, CA) is a well-funded start-up company developing novel industrial mixing technologies for a variety of industries including biofuels, waste water treatment, and pharmaceutical manufacturing. PMI is a spin-out from parent company PAX Scientific â€"a pioneer in the field of biomimetic industrial design â€" applying nature's best designs for efficient fluid movement to man-made systems.

PMI is seeking an energetic and dynamic fluid dynamics engineer to spearhead its computational and experimental research and development program in industrial mixing and thermal mixing processes and impeller design and validation. Because of the small size of the Company the individual will have a broad range of responsibilities with unusual opportunity for rapid growth.

Primary Functions: • Conceive, design and execute advanced 3D computational fluid dynamics (CFD) simulations of fluid flow phenomena in a variety of industrial mixing applications. Simulations will cover both static and rotating mixers and both steady state and time dependant calculations. • Characterize and quantify the fluid systems created by PAX mixers and inserts and apply these characteristics to maximize product performance in application. • Adapt the computationally-based parametric design approach (currently used by parent company PAX Scientific in the field of fan design) to the design of mixing impellers, static mixer inserts. Design and create new features in the tool to tailor it to the requirements of mixer and insert design and allow the control of the unique flow patterns created by PAX mixers/inserts. • Conceive, design and execute scaled mixing experiments to validate and complement numerical analysis. • Develop robust scaling relationships for PMI mixing technologies for real-world industrial mixing applications in a variety of open and closed vessel sizes and geometries. • Work directly with Product Engineers and Technical Sales staff to develop and validate new mixing products for various markets from initial concept, to testing, to client-ready demonstration prototypes for licensing or manufacturing purposes.

QUALIFICATIONS:

• Ph.D. (or Master's degree with sufficient R&D experience) in Mechanical/Aeronautical Engineering with a focus in fluid dynamics. • Experienced user of CFD modeling to simulate and analyze fluid flow in a range of problem types. • Experience in writing computational fluid dynamics code • In depth understanding of fluid dynamics and associated modeling • Proficiency with CAD software. (SolidWorks preferable.) • Experience creating meshes for CFD using commercial packages. • Experience with developing test software. (Labview preferable.) • Experience with Design of Experiments (DOE) techniques. • Strongly motivated to develop technologies with improved energy efficiency, superior performance and outstanding elegance of design
