Computational fluid dynamics (CFD) is an engineering method for simulating the behavior of systems, processes and equipment involving flow of gases and liquids, heat and mass transfer, chemical reactions and related physical phenomena.
Computational fluid dynamics (CFD) is an engineering tool. It simulates how gases and liquids flow. It also examines heat and mass transfer, chemical reactions, and similar physical processes.
More specifically, we can use CFD, or fluid simulation, to
-
Calculate pressure drops through flow meters, valves, etc.
-
Predict aerodynamic lift or drag.
-
Analyze subsonic, transonic, and supersonic flow transitions.
-
Predict rotor thrust.
-
Calculate airflow in air-conditioned rooms.
-
Ensure adequate cooling.
-
Optimize mixing rates.
-
Determine the forces fluids exert on solid bodies (Fluid-Solid Interactions).
-
Visualize airflow and calculate pressures around buildings or cityscapes.
This is a small sample.
Fluid flow analysis technology lets us examine fluid mechanics in different products and processes. It reduces the need for costly prototypes and provides detailed data that is hard to get from experimental tests.
Fluid simulation can complement physical testing. Designers often check new systems with it. They perform this before deciding on validation tests and how many tests they need. Fluid dynamics analysis identifies the root cause of problems during troubleshooting on time.
Analysts can explore many what-if scenarios in a short amount of time when optimizing new designs. This leads to better performance, reliability, and product consistency.
The software we use, ANSYS, continues to innovate. This helps our customers shift from expensive design methods to a simulation-driven product development approach.
