CFD (Computational Fluid Dynamics) is a computer-based method used by engineers to predict how liquids and gases will flow, heat up, cool down, or react chemically. Think of it as a virtual testing environment where engineers can simulate real-world situations on a computer before building anything physical. This saves companies time and money compared to physical testing. Engineers use CFD software to design better chemical plants, improve manufacturing processes, or make products more efficient. It's similar to how architects might use 3D modeling to visualize a building before construction, except CFD focuses on how fluids (liquids and gases) behave.
