CFD Case Studies

Turbomachinery

Centrifugal Pump Performance Optimization

Efficiency Gain: +4.2%

Objective: To minimize energy losses and cavitation risk within a high-capacity chemical transfer pump operating under variable loads.

Methodology: We conducted steady-state and transient simulations using structured hex meshes to map rotating frame interactions, impeller blade passages, and volute designs. Turbulence was modeled using k-omega SST to capture separation boundaries.

Key Results:

• Reduced flow recirculation zone areas by 34%.
• Increased overall pump hydraulic efficiency by 4.2%.
• Mitigated cavitation erosion points by optimizing blade angle incidence.

Smoke & Fire Ventilation

Underground Car Park Jet Fan & CO Study

Fewer Fans Needed: -4 Fans

Objective: Optimize jet fan placement and emergency ventilation performance to clear smoke safely in the event of vehicle fires.

Methodology: Transient fire simulations using discrete fire source models (4MW) and CO gas species transport models. Evaluated visibility limits and toxic accumulation profiles under NFPA and local guidelines.

Key Results:

• Optimized jet fan layout, reducing total fan count from 14 to 10.
• Verified that escape routes remain clear of smoke for at least 15 minutes post-ignition.
• Achieved complete compliance with ASHRAE standards.

Electronic Cooling

Data Center Server Thermal Management

Average Temp Drop: -6°C

Objective: Eliminate localized thermal hot spots in high-density server racks and optimize cold-aisle air delivery containment.

Methodology: Conjugate Heat Transfer (CHT) modeling combining airflow patterns, buoyancy, heat radiation, and conduction inside server housings.

Key Results:

• Removed hot air leakage paths, lowering average rack intake temperature by 6°C.
• Reduced cooling loop fan power consumption by 18%.
• Mitigated thermal throttling risk for maximum compute reliability.
