TurboTides is a turbomachinery design software startup company founded in 2017. TurboTides is an all-in-one integrated platform for turbomachinery design, including 1D modeling, cycle modeling, 3D geometry generation, 2D and 3D CFD and FEA, and optimization tools. As of 2023, TurboTides software is now distributed by Spinpo LLC, my employer.• Managed relationships with rotating machinery design teams of major turbomachinery manufacturers globally with the goal of securing sales, responsible for ~$1M revenue generated• Designed and optimized dozens of turbomachines (radial, axial, and mixed flow compressors, pumps, compressors, and turbines)• Conducted analyses on proposed compressors, fans, and turbine designs and made adjustments to designs to improve efficiency and expand operating range• Suggested design improvements to customers based on aerodynamic, structural, modal analyses• Developed TurboTides training materials from scratch (including manuals, tutorials, guided exercises, and a video library) as well as training materials covering aerodynamic design of radial compressors• Conducted in-depth on-site and remote training for TurboTides customers & prospects• Managed refrigeration centrifugal turbocompressor design project, successfully providing completed design to customer • Collaborated with TurboTides engineering development team to develop new custom features for customers, including integrating a novel AI optimizer (OASIS) into TurboTides• Performed ~75 demonstrations of the software to potential customers and partners • Conducted analyses with ANSYS CFX and ANSYS Mechanical• Created and delivered technical and sales presentations to current and potential customers• Wrote and presented marketing webinars to generate sales leads• Managed and participated in Turbomachinery trade shows

• Conducted aerodynamic design, manufacturing, and testing of seven mixed flow fan prototypes (100 CFM, 1.02 pressure ratio) for forcing air through a novel plasma filtration system developed by Magplasma, participating in a Department of Homeland Security SBIR grant• Design objectives were to minimize housing diameter, axial length while minimizing noise• 1D, 2D preliminary analysis and design optimization using 3D CFD• Optimized flow path, blade angle, tangential stacking, blade thickness of impeller and axial vaned diffuser to create highest pressure ratio design with shortest possible axial length and diameter• Conducted transient analyses to predict cyclical loads and fluid-structure interaction • Conducted modal, structural analyses and optimized design to avoid resonance• Created tolerance stackups for assembly

Startup I founded in 2014 to develop and commercialize a highly efficient, low cost modular axial compressor to compete with centrifugal turbocompressors in high volume applications.• From 2016 to 2020, I led the design, manufacturing and testing of novel 10kW axial turbocompressor technology, including a prototype with designed pressure ratio of 1.15, 87% polytropic efficiency, powered by an integrated 20000RPM permanent magnet motor with novel inside-out design• Produced CAD engineering drawings and tolerancing stackups for prototype assembly with 32 custom manufactured components• Completed CAE, structural and CFD simulations of modular turbocompressor with considerations for manufacturability, tolerancing, modal & harmonic response, and integration of real-time data acquisition during testing• Led team of 4 turbomachinery engineers to successfully complete the prototype, and coordinated outsourced manufacturing/engineering design support• Completed Design Failure Modes and Effects Analysis (DFMEA) to identify and address potential failures in manufacturing, assembly, testing, and long term operation• Managed development of Woven Wheel turbomachinery manufacturing process, which involves manufacturing turbomachinery out of continuous carbon fiber wound in tension around a low-cost 3-D printed mandrelBusiness Accomplishments: • Managed investor relationships and fundraising, raised over $390,000 in start-up capital through investments and grants.
