Labyrinth seal leakage and force estimates are important to the prediction of the stability of rotor-bearing-seal system. The leakage flow is predicted by ANYSYS-CFX in different radial clearance, pressure and whirl speed. It produced labyrinth seal force when the gas flow through the seal. The major goals in this paper were to calculate the rotordynamic(More)
In today's global market,where the concept of super-network is well accepted, it is quite reasonable to assume that members in a supply chain can form a uniform interest community through appropriate coordination mechanisms. Basing on this assumption, we choose profit-maximization of a supply chain alliance as the criterion to analyze the multi-supply(More)
