ANSYS CFX software is a high-performance, general-purpose fluid dynamics program that engineers have applied to solve wide-ranging fluid flow problems for over 20 years. At the heart of CFX is its advanced solver technology, the key to achieving reliable and accurate solutions quickly and robustly.

The modern, highly parallelized solver is the foundation for an abundant choice of physical models that capture virtually any type of phenomena related to fluid flow. The solver and models are wrapped in a modern, intuitive, and flexible GUI and user environment, with extensive capabilities for customization and automation using session files, scripting and a powerful expression language. High Efficiency via High Technology As power plants have become more complex, energy efficient and renewable, the challenges to ensure reliable operation have increased.

With more than 20,000 steam turbines installed worldwide, Siemens has long relied on ANSYS simulation solutions to predict how their products will perform under today’s diverse, demanding conditions. In this article, Leif Paulukuhn, head of Global Steam Turbine Technology at Siemens, explains the critical role of simulation and other advanced engineering technologies in their design efforts.
