It also studies the advantage of the recursion least square method. When theLSM is used in compuring the fault of hydraulic equipment, not only does it save the computerCPU-time and memory, but it also has a high computation speed and,makes it easy to identifythe estimation parameters.展开更多

This paper proposes a completely 2-dimensional modelling in which a 2-dimensional electromagnetic field formulation is used to be coupled with 2-dimensional continuity, momentum and energy equations for an axisymmetrical plasma generator. Typical results show that the calculated flow, temperature and electromagnetic fields near the inlet and inside the coil region, especially at low powers, are quite different from those predicted with previous approaches.展开更多
