Qualification: ME / M.Tech / BE : Thermal /Heat Power/ Mechanical / Automobile Experience Range: 2 to 5 Years Roles & Responsibilities: Perform detailed 3D CFD simulations of internal combustion engines across multiple combustion modes: Diesel, Spark-Ignition (SI), and Hydrogen. Handle the complete simulation lifecycle: a) Pre-processing: Geometry cleanup, mesh generation (sector/full-cylinder), boundary condition definition. b) Simulation Setup & Execution: Selection of appropriate physics modeling(Turbulence,combustion,spray, emission, etc), solver control, simulation execution and troubleshooting. c) Post-processing & Analysis: In-cylinder pressure analysis, heat release rate, emissions prediction (NOx, soot), flame propagation, flow field interpretation and result interpretation. Conduct test correlation and validation using experimental/system simulation data to ensure model accuracy. Provide design and performance recommendations based on CFD insights to support engine development and optimization. Collaborate closely with global counterparts, engine design teams, and test engineers for simulation planning, result interpretation, and design proposals. Ensure best practices, template management, and continuous method improvements aligned with evolving engine technologies and regulatory trends Document simulation procedures, assumptions, model limitations, and publish internal reports and presentations. Must Have: 2+ years of hands-on experience in 3D CFD combustion simulation for internal combustion engines (Diesel/SI/Hydrogen). Proficiency in simulation tools: STAR-CCM+, CONVERGE CFD, AVL FIRE or equivalent. Strong understanding of combustion physics (premixed/non-premixed, spray, ignition), emissions formation, and turbulence-combustion interactions. Exposure to test data correlation and understanding of engine instrumentation (e.g., pressure sensors, emissions analyzers). Ability to define realistic boundary conditions (e.g., injector profiles, wall temperatures, initial conditions) based on engine operating points. Knowledge of combustion strategies (e.g., split injection, EGR effects, H2 mixing). Strong fundamentals in fluid dynamics, thermodynamics, and heat transfer. Excellent analytical skills, communication, and cross-functional collaboration. Willingness to adapt to dynamic simulation demands and collaborate across global teams and time zones. Self-driven personality with a research-oriented mindset and a desire to solve complex combustion challenges. A strong grasp of CFD theory, solver numerics, and model limitations. Flexibility for international travel and and cross-site engagements. Good to Have: Exposure to GT-SUITE for system-level engine performance and boundary condition mapping. Experience in simulation automation and scripting (e.g., Java macros in STAR-CCM+, Python). Experience with post-processing tools (e.g., Tecplot, ParaView, STAR-CCM+ scenes) and report preparation. Understanding of current and future emission regulations and their CFD implications. Automotive or engine OEM experience preferred. Experience with method development, template building, and simulation governance practices. Show more Show less
