• Build CFD models from 3D CAD geometries, applying best practices in meshing and setup.
• Set up physics models and numerical schemes appropriate for engineering problems.
• Troubleshoot simulation issues and ensure reliable outputs.
• Analyze simulation results to extract actionable insights and optimize ventilation system design.
• Collaborate with engineers to improve car park ventilation design (fan placement, duct sizing, inlet / outlet placement).
• Conduct iterative simulations to meet required standards for ventilation performance.
• Lead or contribute to CFD studies related to :
• Fire and smoke dispersion in underground car parks, tunnels, and stations
• Pedestrian comfort and air quality modeling
• Hydraulic modeling for water utility installations
• Provide fluid dynamics and thermal consultation to interdisciplinary teams.
• Participate in project technical meetings and internal stakeholder communications.
• Use 1D simulation data to enhance and validate 3D CFD models.
• Perform engineering calculations including fire curves, Heat Release Rate (HRR), ASET / RSET.
• Conduct HVAC load calculations using HAP / IES software.
• Design HVAC systems, ductwork, and piping layouts using CAD tools.
• Select appropriate HVAC equipment based on simulation data and system requirements.
• Integrate sustainable engineering practices to reduce environmental impact.
