Computational Fluid Dynamics (CFD) is an advanced engineering method used to analyze the behavior of liquids and gases through numerical calculations performed by high-performance computing systems. CFD simulations allow engineers to accurately predict velocity fields, pressure distributions, temperature gradients, turbulence effects, and heat transfer processes before physical testing is performed.

Today, CFD analysis services have become an essential part of product development and validation processes across industries such as defense, aerospace, automotive, energy, marine, and heavy manufacturing.

How is CFD Analysis Performed?

A professional CFD engineering analysis typically consists of the following stages:

1. Geometry Preparation

The CAD model of the product or system is prepared, and the fluid domain is defined.

2. Mesh Generation

The geometry is divided into millions of small computational cells to enable numerical solution. Mesh quality is one of the most critical factors directly affecting CFD accuracy.

3. Physics Model Definition

Depending on the analysis requirements, appropriate models are selected:

Turbulence models (k-epsilon, k-omega SST, etc.)

Heat transfer models

Multiphase flow models

Compressible or incompressible flow

Combustion and reaction models

4. Boundary Condition Definition

Inlet velocities, pressure values, temperatures, and environmental conditions are defined.

5. Numerical Solution (Solver)

The Navier–Stokes equations are solved iteratively to compute the fluid flow field.

6. Post-Processing and Evaluation

Velocity, pressure, temperature, and force distributions are evaluated to determine system performance.
