What is CFD?
Computational Fluid Dynamics (CFD) is a powerful engineering tool that uses computer simulations to predict how liquids and gases move, mix, and interact with surrounding objects. Think of it as a virtual wind tunnel or a digital flow laboratory.
It allows engineers to understand, predict, and optimise complex fluid behaviour, leading to better designs, reduced costs, and faster innovation, all before a single physical prototype is built.
What are the steps in CFD?
Geometry & Mesh:
We start with a 3D model of your product or environment. Then, this model is divided into millions of tiny 'cells' to prepare it for analysis.
Physics & Boundary Conditions: Next, we tell the computer about the physical properties of the fluid (e.g., air, water, oil) and define how it interacts with its surroundings – such as flow rates, temperatures, pressures, or how walls affect the flow.
Simulation & Solving: Computers then solve complex equations (the governing laws of fluid dynamics) for each tiny cell, predicting the fluid's behaviour across the entire system.
Results & Visualisation: Finally, we interpret the vast amounts of data, creating intuitive visualisations like flow streamlines, temperature contours, and pressure maps, which help to understand inefficiencies and areas of improvement.
