AI/Simulation Engineer (Computation Fluid Dynamics - Combustion)

Responsibilities

• Develop and execute CFD simulations for refrigerant leakage, gas dispersion, and ventilation analysis
• Model multiphase flows, multi-species transport, and transient flow behavior
• Perform fire and combustion simulations, including ignition, flame propagation, and heat release
• Analyze hazard scenarios such as confined space leakage, accumulation, and flammability limits
• Apply appropriate boundary conditions for leak sources, mass flow rates, and environmental conditions
• Conduct steady-state and transient simulations for leak evolution and fire scenarios
• Interpret results to identify risk zones, ignition probability, and mitigation strategies
• Support V&V activities, including comparison with test data and literature correlations
• Prepare technical reports highlighting assumptions, risks, and safety insights
• Collaborate with cross-functional teams on safety, compliance, and product design

Requirements

• Bachelor's or Master's in Mechanical, Chemical, or Aerospace Engineering
• 4–8 years of experience in CFD with a focus on fluid flow and safety modeling
• Strong fundamentals in fluid dynamics, turbulence, heat transfer, and multiphase flow
• Proficiency in CFD tools such as ANSYS Fluent, CFX, STAR-CCM+, OpenFOAM, or COMSOL
• Hands-on experience in refrigerant leakage modeling, gas dispersion, and fire/combustion simulations
• Understanding of flammability limits, hazard assessment, and transient flow dynamics
• Strong technical documentation and communication skills

Preferred Qualifications

• Exposure to HVAC or refrigeration systems
• Familiarity with safety or regulatory-driven simulations
