Key Responsibilities
Key Responsibilities
- Correlate models with test data for torque, power, air mass, BSFC, temperatures, and pressures, documenting assumptions and correlation quality.
- Simulate full load and part load maps, steady state, and transient conditions to support performance, drivability, and thermal assessments.
- Conduct DOE and optimization studies to explore design and calibration options such as valve timing, boost, turbo sizing, and heat rejection.
- Translate insights from 3D CFD and testing into accurate 1D models, discretizing system components and applying loss and heat transfer models.
- Develop and enhance modeling methods, templates, and procedures for setup, correlation, and coupled analyses.
- Process large datasets for efficient analysis, visualization, and reporting.
- Provide design and calibration recommendations based on model results and sensitivity analysis at component and system levels.
- Communicate findings through reports, presentations, and technical reviews with cross-functional teams.
- Bachelor’s degree in Mechanical, Automotive, Aerospace Engineering or related field.
- 1-3 years of experience with propulsion simulation, GT Suite/GT Power, or similar tools.
- Strong understanding of combustion engines, thermodynamics, fluid dynamics, and heat transfer.
- Experience building, correlating, and evaluating 1D models and working with engine testing data.
- Proficiency in data analysis and scripting (e.g., Python).
- Excellent communication skills and attention to detail.
- Master’s or PhD in a related field with emphasis on engines or fluid mechanics.
- 5 years of advanced GT Power experience, including optimization and coupled modeling.
