Virtaussimuloinnit, often referred to as computational fluid dynamics (CFD) in English, are numerical methods used to analyze and predict fluid flow, heat transfer, and related phenomena. These simulations involve solving the fundamental equations governing fluid motion, such as the Navier-Stokes equations, on a computer. The process typically begins with defining the geometry of the problem domain and discretizing it into a mesh of smaller control volumes or elements. Boundary conditions, representing physical constraints at the edges of the domain, are then applied. The governing equations are then solved iteratively for each cell in the mesh, calculating properties like velocity, pressure, temperature, and turbulence.

CFD simulations are employed across a wide range of industries. In automotive engineering, they are used to optimize aerodynamic designs for fuel efficiency and performance. Aerospace engineers utilize CFD to design aircraft wings and predict airflow characteristics. Within the medical field, simulations can model blood flow in arteries or airflow in lungs. Other applications include HVAC system design, chemical process engineering, and environmental studies. The results of these simulations provide valuable insights into fluid behavior, allowing for design optimization, troubleshooting, and prediction of performance under various conditions, often reducing the need for extensive and costly physical prototyping.
