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:
A scientific, data-driven basis for engineering and optimization.
From capability to application, the real value of CFD lies in how it is applied.
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:
This applied approach is driven by experience, not just software proficiency.
The strength of HY lies in Applied CFD, driven by deep industrial exposure and a solid understanding of CFD fundamentals. Engineers bring hands-on experience across a wide range of applications—including built environments, data centres, transformer and generator substations, shipping, multiphase flows in mining industries, and electronic hardware.
This physics-led approach consistently delivers actionable insights into system and product behavior, creating measurable business impact for clients.
These strengths translate directly into a broad and proven set of capabilities.
Thermal performance is a critical factor influencing the reliability, safety, and operational life of underground transformer substations. HY’s CFD-driven approach delivers Complete visualization of complex airflow and temperature fields, quantitative assessment of fan performance and ventilation effectiveness, optimization of exhaust ducting and overall thermal layout.
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.
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.
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 can optimize CDU sizing, heat exchanger effectiveness, and rack-level heat removal.
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, enhancing thermal performance.
HY has multiphase CFD capabilities in analyzing and optimizing equipment such as slurry mixers, cyclone separators, and related process devices. 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.
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.
