Fire and Life Safety

Thermal Comfort Analysis

I perform detailed thermal comfort and indoor environmental quality assessments to ensure occupant well-being while optimizing energy performance.

Scope of work:

• CFD-based thermal comfort modeling

• PMV/PPD and local discomfort analysis

• Air velocity, temperature, and radiant asymmetry assessment

• HVAC diffuser and return optimization

• Hot climate design considerations (Middle East)

Tools:

• ANSYS Fluent / CFX

• COMSOL Multiphysics

• Coupled CFD–HVAC simulations

Evacuation Modeling & Crowd Dynamics

I model human movement and behavior during emergency and non-emergency conditions to evaluate safe egress, congestion, and evacuation efficiency.

Capabilities:

• Pathfinder evacuation modeling

• Occupant load estimation and distribution

• Flow rate and bottleneck analysis

• Staircase and exit capacity assessment

• Interaction between smoke conditions and evacuation

Crowd dynamics analysis:
