Study on micro modeling equipment of condenser-throat

Combing with comparability principle, and on the premise of satisfying the same flow state, using the method of modelling blew, simulating the steam of turbine with flow air. This paper puts forward a kind of micro modelling equipment of condenser-throat and gives the design project of the micro modelling experiment, and the feasibility analysis to the micro modelling equipment is studied. Influence proportion of different equipments was compared in flow resistance and flow state respectively. On this basis, analysis of the influence of body and inner-equipment on the flow resistance, which mainly includes the disturbance by the body, sticking effect of the body, the flow resistance by the low-pressure heater and so on, and gets the curve of steam flow resistance with the dimension of body structure and inner-equipment.
