What is CFD?

June 13, 2011 kamran.fouladi

CFD is state-of-the-art computer-based simulation predicting what will happen when fluids (e.g., air, water or gases) flow. Using numerical methods and algorithms, CFD provides the ability to visualize and understand the complicated flow phenomena for systems too challenging and expensive to prototype. The factors affecting the path of flow such as objects and boundary conditions are mapped to a three-dimensional computational domain that is subdivided to small and finite volumes. The governing non-linear differential equations of fluid dynamics are then solved in the computational domain using high-performance computers and performing millions of calculations. The solutions to these equations are usually presented in graphical form as flow patterns. CFD analysis for data centers provides the virtual modeling of the room complete with IT and cooling equipment to help visualize and understand complicated airflow and thermal patterns in the room.
