CFD Analysis Services

Practical HVAC CFD studies scoped to address your specific design question — from air distribution and thermal comfort to contaminant control and exhaust performance.

01 — HVAC CFD Analysis

Air Distribution CFD

Evaluate supply air throw, stratification, short-circuiting, stagnant zones, diffuser performance, return/exhaust placement, and high-ceiling space air movement.

  • Supply air throw and diffuser jet behaviour
  • Thermal stratification and layering assessment
  • Short-circuiting between supply and return/exhaust
  • Identification of stagnant or poorly ventilated zones
  • High-ceiling and atrium air movement
  • Return and exhaust placement optimisation

02 — Thermal Comfort Analysis

Thermal Comfort Studies

Assess occupant comfort using temperature gradients, velocity distribution, draft risk, radiant effects where applicable, and project-specific comfort targets.

  • Temperature gradient mapping across occupied zones
  • Velocity distribution and draught risk assessment
  • PMV/PPD comfort index evaluation
  • Operating temperature analysis
  • Asymmetric radiant temperature effects
  • Project-specific comfort performance criteria

03 — Ventilation Effectiveness & Age of Air Analysis

Age of Air & Air Change Effectiveness

Analyze ventilation effectiveness, fresh air distribution, local mean age of air, air change effectiveness, and areas with poor ventilation performance.

  • Local mean age of air mapping
  • Air change effectiveness evaluation
  • Fresh air distribution across occupied zones
  • Identification of poorly ventilated areas
  • Ventilation effectiveness benchmarking
  • Support with ventilation design criteria

05 — Exhaust Capture Analysis

Exhaust & Capture Performance

Review exhaust placement, capture effectiveness, make-up air interaction, cross-contamination risk, and airflow paths for specialized rooms and process exhaust applications.

  • Exhaust hood and grille placement optimisation
  • Capture effectiveness under varying airflow conditions
  • Make-up air supply and interaction with exhaust
  • Cross-contamination risk assessment

Compare multiple HVAC layouts, diffuser selections, supply temperatures, airflows, or exhaust strategies to support design decisions.

  • Side-by-side comparison of HVAC layout options
  • Diffuser type and placement evaluation
  • Supply air temperature and flow rate optimisation
  • Exhaust strategy comparison
  • Ranked performance against comfort and ventilation criteria
  • Design decision support documentation
