Science and technology have advanced drastically over the past few decades, enabling engineers to create more capable and efficient machines/infrastructures than ever.

Computational Fluid Dynamics is one such technology that uses modern and accurate concepts and methods to understand the fluid flow to evaluate the performance of a design and determine its efficiency.

The world we live in is a juncture of interactions between solids, gas, and liquid. Therefore, understanding and abiding by the nature of these elements and their impacts become ubiquitous for successful designs.

Computational Fluid Dynamics or CFD helps understand the flow and fluid transfer in the entire design process, which helps in design optimizations. Let’s see how engineers can utilize this cutting-edge technology for practical applications…

How Does Computational Fluid Dynamics Work?

Computational Fluid Dynamics is a branch of fluid mechanics that uses numerical analysis and algorithms to solve complex problems related to fluid flow. For example, partial differential equations (PDEs) quantify gas and fluid flow.

The PDEs represent high-performing computer software solving mass, momentum, and energy conservation laws. In addition, the simulations of boundary conditions help understand the interaction of liquids and gasses with surfaces.

The CFD software uses Navier-Stokes Equation to solve the problems and obtain solutions. For example, using the FCD software, engineers can solve fluid flow-related problems like flow velocity, density, temperature, and chemical concentrations.
