On Aerothermal Optimization of Low-Pressure Steam Turbine Exhaust System
… computational cost due to the complexity of LPES geometry. To make things worse, designers have to consider extra cost caused by change of constraints, multi-objective and multi-disciplinary optimization. The second is the vulnerability of optimization due to the lack of comprehensive validation …
