Computational Fluid Dynamics (CFD) utilizes several numerical approaches to solve three-dimensional fluid flow problems. CFD is extensively used for industries such as aerospace, automotive, HVAC, building external and internal analysis, manufacturing, product design, etc.

CFD works out to be a quick & effective tool to predict the performance of the system in design stages, ensuring safe, efficient and engineered solutions.

CFD Analysis helps to understand complex flow problems. Performance of the system can be analyzed in the early design stages making the design process flawless, efficient and shorter turnaround time for development work. In the building design, CFD can be used to analyze external flow such as building aerodynamics and wind load as well as the internal flow analysis including thermal comfort, contaminant control and smoke control thus providing a safer greener design.

Fire and Smoke control is a major challenge in buildings. Using CFD analysis temperature and smoke generation can be visualized and it is ensured that smoke control system meets the relevant safety codes. Staircase pressurization, zone modeling for smoke control can also be analyzed to ensure safe escape of occupants.

Carbon-monoxide (CO) control is a major challenge in covered car parks. By using CFD Analysis, we ensured that the ventilation system meets the NBC, ASHRAE and WHO guidelines for CO exposure and contaminant control.

The CFD Analysis of the data-center facility is done to predict airflow patterns, temperature distribution. The hotspots and recirculating zones around the racks can be identified and eliminated. The study is further extended to get detailed information of the Rack Cooling Index (RCI) and effective & optimized air distribution.

In a commercial kitchen, working conditions are especially demanding. Ventilation plays an important role in providing comfortable and productive working conditions and in securing contaminant removal. By CFD Analysis, we ensure that the removal of high heat loads, steam generation, food odors and contaminants.

For industrial applications meeting the process requirement of specific temperature and humidity with human comfort is difficult to achieve and mostly results in over-sized HVAC equipment and insufficient system. CFD Analysis helps to evaluate the air distribution inside the concerned space and achieve process requirement efficiently with human comfort as well as contaminants removal.

CFD helps to predict pressure drops in AHU, and optimize the design to reduce the pressure drop and best utilizing the energy of fans. It helps to analyze airflow patterns and velocities across the different components such as filters, coil, inlet box, plenum etc. CFD Analysis can be further used to optimize the velocity distribution and gain maximum output from the AHU.

CFD can be used to analyze the ventilation system design for bio-safety labs. Factors such as fume containment, safety of the working person, pressure gradient relative to adjacent areas, filtration, air changes per hour (ACPH), temperature and humidity requirements necessary to design the ventilation system to meet requirements.

Design and optimization of turbo-machinery prediction of operating curve for fan and pumps blade, housing design & optimization based upon head and flow requirements. Prediction of the operating curve at different impeller speed, and cavitation analysis, particle erosion analysis are performed to get best available efficiency and life.
