Projects

The project is dedicated to the study of energy loss mechanisms in full tubular pump which is a novel electromechanical integrated turbopump and to the key technologies for comprehensive optimization. The research specifically includes: the energy dissipation characteristics of full tubular pump operating under stall condition, the fluid–structure interaction characteristics of full tubular pump, the response mechanism of the air gap design and the heat transfer characteristics based on the solid-magnetic-thermal coupling and the formation mechanism of the stator-rotor clearance flow based on the fluid-solid-thermal coupling. By conducting model test and multi-fields coupling simulation, the energy dissipation characteristics of full tubular is explored and the turbulence motion and heat transfer process are simulated. The final goal of this research is to understand of the effect of stator-rotor clearance flow on full tubular pump unit performance and its energy loss mechanism operating under stall condition, thus the comprehensive optimization of the novel electromechanical integrated turbopump, greatly promoting its application and energy conservation.
