  • Conduct application-specific cooling system analysis; develop cooling system layouts and optimize cooling air and water systems using 1-D simulation tools for up-front system sizing and component selection.
  • Perform high-end Computational Fluid Dynamics (CFD) simulation for virtual design and validation — including component CFD to determine performance characteristics of heat exchangers, pumps, radiators, and aftercoolers.
  • Develop CFD models to understand airflow through cooling packages and underhood thermal models to predict component temperatures.
  • Collaborate with design partners to meet technical and regulatory requirements; correlate analysis models with test engineers to validate simulation accuracy.
  • Perform analysis to assist in resolving cooling-related field problems; determine root causes of issues and communicate design improvement recommendations to product development teams.
  • Help establish technical requirements and specifications for new products; contribute to continuous improvements in simulation methods and processes.
