Develop and execute 1-D system-level simulations using GT-SUITE for DU and SU applications.
Build an understanding of DU/SU architecture, components, operating characteristics, boundary conditions, and system interactions.
Develop, maintain, and improve GT-SUITE models for component- and system-level analysis.
Perform pressure-drop, flow-performance, and thermo-fluid system analysis for DU/SU applications.
Support the development and improvement of Fast Running Models (FRMs) for integrated DU/SU performance evaluation.
Work closely with CMHF technical experts during the knowledge transfer and capability-development phase.
Reproduce and assess established models and use cases to understand the GT workflow, assumptions, modelling methodology, and post-processing approach.
Correlate and validate 1-D models against available test data and/or higher-fidelity simulation results, where applicable.
Perform sensitivity studies and provide sound engineering interpretation of simulation results.
Interact with customers to gather input requirements and present the simulation findings by interpreting and explaining the physical significance of the results to them.
Establish standard modelling practices, templates, documentation, and simulation workflows for long-term capability within CTCI.
Collaborate with CFD, product engineering, testing, validation, and other cross-functional teams for system-level problem solving.
Gradually take independent ownership of 1-D simulation Work Requests and provide clear technical recommendations to stakeholders.
Skills and Experience Required:
Bachelor’s or master’s degree in mechanical, Automotive, Aerospace, or a related engineering discipline, with a strong foundation in thermo-fluid sciences and system simulation.
Relevant hands-on experience in 1-D system simulation is preferred. GT-SUITE experience should be prioritized over prior DU/SU product experience.
Good understanding of 1-D thermo-fluid and system-simulation fundamentals.
Experience with GT-SUITE, GT-POWER, or a comparable 1-D system-simulation tool.
Strong fundamentals in fluid mechanics, thermodynamics, heat transfer, pressure-drop modelling, and flow-system modelling.
Ability to develop, debug, and interpret physics-based simulation models.
Understanding of model correlation and validation methodologies.
Ability to interpret engineering drawings, test data, boundary conditions, and system requirements.
Knowledge of Simulink/ Matlab is desired but not essential.
Preferred (Good to have skills):
Hands-on experience with GT-SUITE.
Experience in automotive, engine, fuel-system, dosing-system, aftertreatment, pump, or fluid-delivery system simulation.
Experience developing reduced-order models or Fast Running Models.
Exposure to 3-D CFD and an understanding of how 3-D analysis complements 1-D system simulation.
Exposure to simulation automation and data processing using Python or MATLAB.
