Unstructured tetrahedral meshes are used to simulate the flow field inside high pressure combined valves of a 600mw ultra supercritical steam turbine under the nominal condition.

Secondly, model output tracking robust control is proposed under the large-scale mode aggregation and the condition that the controlled nominal system is similar to the reference model.

Then it analyzes the interaction among the inflows of foreign fund under the condition of its unsymmetrical flow, domestic nominal interest rate, and inflation of currency, as well as the limit…
