Advanced simulation software, known as Computational Fluid Dynamics (CFD) is capable to model real world ventilation, wind dispersion and energy-related problems in buildings. This state of the art tool is used during (preliminary) design to maximize efficiency and safety of built environments. CFD Freelancing can help you with Building Engineering CFD simulations.

Wind Studies – Building Engineering CFD application for external aerodynamics
The cost-efficient yet accurate study of built environment is done these days via Computational Fluid Dynamics. Wind tunel testing of scale models of large buildings can quickly become expensive and time-consuming while CFD offers a wide range of analysis by using computers only. The numerical simulation provides the building services engineer with wind velocities and patterns, dispersions, temperature profiles, pressures on walls and pedestrian comfort.
Results from a wind simulation:
- Determination of the dispersion of potentially toxic chemicals, exhausts, mist and odsors to sensitive areas such as windows and pedestrian areas
- Wind flow fields and pressures on and around buildings
- Wind pattern on pedestrian levels to determine pedestrian comfort
- Analysis of wind velocity impact on ground floor shops and terraces at different wind directions and speeds
Examples:
- University buildings
- Industrial campuses
- Urban environment
- Street canyons
- Hospitals and labs
- Power plants
- Cooling tower effects
Wind Studies – application of CFD for external aerodynamics of high built structures
Ferris Wheel CFD Aerodynamics. Red color represents high aerodynamic force on the structure.
High structures such as Amusement Park equipment can experience high wind loads in storms. To make sure that the force acting on the structure does not harm the expensive equipment, the engineer has to consider every extreme situtations.
A CFD simulation of extreme wind conditions can point out the areas where the highest aerodynamic force act. The load on the structure can be decreased by careful aerodynamic optimization of the shapes.
Moreover, a fluid dynamic simulation of an amusement park equipment can provide the structural engineer with the necessary loads to calculate with.
An additional example for highly built structures, where CFD can be very useful are antennas.

Data center design using Computational Fluid Dynamics
Data centers can consume more energy than most other facilities. Because of their critical nature, businesses tend to oversize the HVAC equipment in order to prevent any potential damage to the costly electronic hardware.
CFD modeling has become a very important part of green data center design. The performance of the HVAC ducting, fans and air conditioning can be accurately evaluated improved to get the highest efficiency thus lowest operating cost possible by keeping a desired safety margin as well. Many “what-if” scenarios can be simulated to assess potential harm to the computers.
CFD can be used to simulate any data center sizes from small to large.
Results from a server room CFD:
- Air patterns and their cooling efficiency on the computer equipment
- Alternative design scenarios for rack sizes and positions
- Analysis of electronics cooling inside racks
- Assessment of Computer Room Air Conditioning (CRAC) system failure – transient simulation of overheating
- Smoke propagation analysis in data centers
Examples:
- Critical computer centers
- Telecom centers
- Emergency power generation rooms (hospitals, schools etc.)
- Web server rooms
- Supercomputer rooms
- CFD of electronics cooling (liquid or airflow)

Smoke Simulation using Building Engineering CFD
CFD models can be used to determine the impact of potential fires and smoke on various building designs. CFD fire analysis allows us to simulate smoke development and smoke dispersion as well as smoke ventilation in built environments. Information from the CFD simulation allows engineers to better design the smoke mitigation system and the ductwork therefore reducing building and operation costs.
- CFD analysis of the effects of smoke and fire on interior spaces
- Improved efficienty of smoke management ventilation systems
Types and sizes of interior spaces that can be simulated via CFD:
- Atriums and auditoriums
- Server and data center rooms
- Office buildings
- Civil buildings
Clean Room Computational Fluid Dynamics
The use of CFD simulation in a clean room allows the engineer to gain insight into their designs with regard to flow patterns and fields, particle dispersion, ventilation and temperature uniformity. CFD is a great tool to either double-check or improve existing interior and ductwork designs.
Results from a clean room simulation:
- CFD analysis of particulate controlled spaces
- Calculation of flow fields
- Dispersionhttps://cfd-freelancing.com/portfolio/building-engineering/
- Identification of recirculation zones and “age of air” values indicating badly ventilated areas
Examples:
- Robotics
- Manufactures
- Any class of clean spaces or controlled environment warehouses
- Semiconductor industry
- Healthcare operation rooms
