Why CFD?

Computational Fluid Dynamics (CFD) enables detailed evaluation of system behavior and performance at the design stage. By resolving flow, heat transfer, and related physical phenomena, CFD supports informed engineering decisions and delivers: 

  • Significant cost savings by reducing physical prototyping and design iterations
  • Early identification and mitigation of technical risks
  • Design insights that are often inaccessible through experimental measurements alone

A scientific, data-driven basis for engineering and optimization.

From capability to application, the real value of CFD lies in how it is applied.

Applied CFD/CAE at HY

At HY, CFD is practiced as an applied engineering tool, not a purely academic exercise. Built on a strong foundation in

Electrical and Mechanical consulting, CFD is integrated directly into real-world design workflows across:

  • Built Environment
  • Transformer Substations
  • Underground power cables
  • Data Centres
  • Electronics

This applied approach is driven by experience, not just software proficiency.

Project highlights

Residential/Commercial Buildings

Comfort, safety, and energy efficiency begin with effective ventilation design. Using CFD, we analyze airflow patterns, temperature distribution, and ventilation effectiveness at the early design stage—well before construction starts. This empowers architects, consultants, and developers to make data-driven decisions that enhance occupant comfort, improve indoor air quality, and significantly reduce the risk of costly redesigns later.

Transformer Substations

Thermal performance is a critical factor influencing the reliability, safety, and operational life of underground transformer substations. Conventional design methods based on thumb rules and simplified calculations often fall short in representing real operating conditions.

HY’s CFD-driven approach delivers quantitative assessment of fan performance and ventilation effectiveness. Optimization of exhaust ducting and overall thermal layout

Agriculture/Urban Farming

CFD-based parametric studies are used to optimize air and water flow distribution in slotted pipe systems for enhanced vegetation growth. The analysis reveals strongly counterintuitive flow distribution mechanisms, leading to pipe configurations that conventional design intuition—even among experienced engineers—would typically overlook.

Underground Power Cables

In urban cable tunnels and underground substations, CFD models the coupled effects of cable heat generation, tunnel airflow, and soil conduction. The simulations expose thermal bottlenecks and quantify ventilation effectiveness. Cable layout and spacings are optimized to maintain safe operating temperatures, deliver realistic ampacity estimates, ensuring long-term reliability.

Data Centers

Thermal management of high-density server racks is critical to data centre reliability. CFD is used to predict airflow and temperature distribution, validate hot-aisle/cold-aisle containment, and optimize HVAC performance in air-cooled facilities. For liquid-cooled data centres, CFD resolves coolant flow distribution, CDU sizing, heat exchanger effectiveness, and rack-level heat removal for direct-to-chip and immersion systems. This integrated CFD and consulting expertise delivers end-to-end mechanical engineering solutions that control hotspots, maintain inlet temperature compliance, and support reliable operation of high-performance data centres.

Refrigeration

Condensers in refrigeration units, chillers, and heat pumps operate as multiphase heat exchangers. Advanced multiphase CFD is used to resolve phase change, void fraction distribution, heat transfer coefficients, and flow maldistribution within condenser tubes. These insights enable precise optimization of tube geometry and circuiting, reducing pressure drop, enhancing thermal performance, and improving overall system efficiency—resulting in substantial, quantifiable operational cost savings.

Slurry flow

Performance of slurry-handling equipment in the chemical and process industries is strongly influenced by complex interactions between immiscible phases. CFD models such as Full Eulerian, Volume of Fluid (VOF), and Mixture approaches are employed to resolve interactions between immiscible phases, including phase distribution, slip velocity, and separation behavior. HY has proven multiphase CFD capabilities in analyzing and optimizing equipment such as slurry mixers, cyclone separators, and related process devices.


Electronics

Effective thermal management is fundamental to reliable electronic hardware design and operation. Our experience in diagnosing and resolving burnout issues, combined with applied CFD expertise, enables delivery of reliable thermal design solutions for electronic systems operating under demanding conditions.
