Research on Internal Flow of Power System and Thermal-Power Conversion Chief Scientist: Xiaoyun Han (Institute of Engineering Thermophysics, Chinese Academy of Sciences) This project studies the law of the state of the total energy system and its interaction with each other and the change of state, Create a system of generalized theory of sustainable energy systems that takes multi-criteria of efficiency, transformation, environmental protection, economy and safety into account. Research on optimization and synthesis of total energy system, development of process topology and parameter synchronization optimization software, establishment of design, improvement of system and discovery of new methods, disclosure of holographic performance of advanced coal-powered energy systems, development of new systems, formation of coal-power conversion computer Integrated system. Research, put forward several future new energy - a new process of powertrain and ways to achieve. To study the theoretical model of unsteady flow in multi-stage environment and the accurate calculation method of high-speed and high-stability time, and to develop corresponding analysis software package and pneumatic design tools. Studying the mechanism and control strategy of flow instability, revealing the law of the precursor of flow instability and exploring new methods of controlling the stability and instability. The turbulent eddy system, the blade gap flow, the advanced cooling and other unsteady flow fine structure, the geometric parameters and the unsteady flow are interrelated, and the new concept of unsteady composite bending and twisting blade is explored, and the method and realization of novel blade geometry modeling are studied way. The steady and transient vapor-liquid two-phase and multi-phase flow laws, phase interface dynamics and heat and mass transport mechanisms are studied. To study non-axisymmetric structure caused by unsteady flow, cross-problem hybridization problem, flow field characteristics evaluation, integration of the related research results, the development of steam turbine, gas turbine quasi-quaternary design system.
