Turbomachinery & Piping System Computational Fluid Dynamics
Pressure contours and velocity vectors for flow through first stage blades are determined from computational fluid dynamics codes. Boundary element codes determine heat transfer coefficients that are then used in thermal and stress analysis of the blades.

Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. For many years, the study of dynamics, heat transfer, combustion, and fluid-structure interaction were unthinkable without the help of CFD, and this dependence has increased as more of the flow becomes amenable to numerical prediction. It is clear that CFD plays a significant role in the effective design, application, and performance evaluation of gas turbines and modern piping systems.
At Southwest Research Institute (SwRI), CFD is used comprehensively to solve turbomachinery fluid/thermal problems in tandem with experienced review staff and experimental verification of results. Its use in internal flow investigations is usually focused on examining phenomena such as:
- Pressure/velocity profiles
- Thermal transients
- Acoustic/mechanical resonances
- Effects of multiple operating conditions
