We are seeking a skilled CFD Engineer with experience in project-based consulting, ANSYS Fluent, HAP, and IES software. The ideal candidate will have a deep understanding of Computational Fluid Dynamics, heating and ventilation system design, and energy modeling.

Responsibilities

Perform high-quality CFD simulations to analyze airflow, pollutant dispersion, and thermal distribution.
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.
