Rotating Machinery Thermal Simulation

Rotating machinery thermal simulation helps to address effective cooling of components, evacuate excess heat, and protect the machine from temperature-related failures.

Simulating the cooling of a full-scale rotating machine with complex geometry requires substantial time and effort. As an alternative, engineers either analyze individual sections of the machine separately or utilize simplified 1D models with limited information about the geometry. The results obtained from simplified models are not ideal for all stages of machine development.

Using a CAD integrated CFD solution, simulation engineers from Siemens Gas and Power division were able to obtain the full simulation results for a gas-cooled complex rotating machine, SGen-3000W series.

Thermal analysis of turbo generator

Full-scale thermal analysis of turbo-generator is a time-consuming task. To minimize effort and resources, engineers often try to utilize multiple simulation models with several assumptions. The resulting analysis insight cannot be of use during all stages of machine development.

While developing a cooling concept of gas-cooled turbo-generator, SGen-3000W series, Siemens engineers encounter a similar challenge — How to eliminate inefficiencies arising out of using both computational fluid dynamics (CFD) and 1D analysis during the design phase? How to perform a full-scale turbo-generator simulation with all sub-sections cooler, stator, blower, and rotor with limited effort and resources? A CAD integrated CFD software provides the solution to our Siemens colleague at the Gas and Power division.
