How CFD Works

CFD relies on mathematical models and computational power to solve the governing equations of fluid dynamics, such as the Navier-Stokes equations. The process begins with defining the problem, creating a geometrical model, and dividing it into smaller elements through meshing. Numerical methods are then applied to simulate the flow behavior within these elements, generating detailed insights into parameters like pressure, velocity, and temperature.

Applications of CFD

CFD is widely used in industries such as aerospace, automotive, and energy. In aerospace, it helps design efficient aircraft by studying aerodynamics. In the automotive sector, it optimizes vehicle performance by analyzing airflow, cooling systems, and combustion processes. CFD also contributes to renewable energy, enhancing the efficiency of wind turbines and hydroelectric systems. Additionally, it is used in medical research to study blood flow and in environmental studies for weather prediction and pollution control.

Advantages of CFD

CFD provides a cost-effective and time-saving alternative to physical testing. It allows engineers to simulate complex fluid behavior in a controlled virtual environment, reducing the need for prototypes. CFD also enables the study of scenarios that may be challenging or dangerous to replicate in real life, offering greater flexibility in experimentation.
