Ensuring car parks are ventilated to prevent the buildup of toxic fumes and flammable gasses is critically serious. 

Physical fire tests help to predict fire behavior and spread and understand the dynamics of fire development such as Comprehensive & Realistic Fire Dynamics Simulation, and Fire Smoke Dispersion Analysis.

The use of CFD  simulation allows us to solve the flow problem with a computer, and obtain precise results. This, in turn, optimizes computation time and resources, as well as calculates the magnitude and direction of the velocities.

HVAC engineers optimize designs using CFD simulation to investigate new heating, air conditioning, or refrigeration system designs and find root causes of performance issues. CFD Achieves operational goals by controlling microclimates, thermal comfort, and air quality compliance. 

Calculations and CFD reports contain the following aspects for technical readers: experimental design, turbulence model and auxiliary heat transfer and flow models, boundary conditions, numerical methods, assessing CFD predictions, and drawing conclusions. 

A proper indoor environment in buildings is crucial for the occupant's comfort. CFD studies have analyzed the impact of increased CO2 concentrations on indoor air quality (IAQ) complaints and health symptoms in buildings

High temperatures can increase the risk of failure of server hardware such as central processing units (CPUs), hard drives, and memory storage, causing very large losses in important and confidential stored information , in addition to the loss of huge amounts of money. Here is the importance of CFD in simulating the efficiency of  cooling units to avoid this damage caused by high temperatures

Misting systems are important for several reasons, especially in hot, dry climates. Its importance lies in cooling, enhancing comfort, health benefits, and improving air quality. The CFD enables engineers to understand how misting systems interact with their environments, improve performance, and address safety, efficiency, and environmental concerns.
