Aerothermodynamics of Low Pressure Steam Turbines and Condensers

Avoiding Stressed-Out Steam Turbines

assembly, Pro/ENGINEER CAD geometry was imported into ANSYS Mechanical software and meshed using SOLID185 elements. Frictionless surface-tosurface contact pairs with augmented Lagrangian algorithms were created between mating surfaces. A matching node pattern was maintained at the root and slot pressure faces, where load transfers take place between the two components. As an in-house design pra...

Simulation Techniques in Hypersonic Low-density Aerothermodynamics

Hypersonic rarefied flows near a wedge, disk, plate, and sphere were studied under the conditions of wind-tunnel experiments [1-8] and hypersonic flights. The direct simulation MonteCarlo (DSMC) method [9] is used to study the influence of similarity parameters on aerodynamic coefficients in He, Ar, N2, and CO2. It is found that, for conditions approaching the hypersonic stabilization limit, th...
