Self-oscillation Chamber Design And Flow Field Analysis Of Pipeline Supercharger

Pipeline supercharger is widely used in hydraulic systems such as ships, cars, heating systems etc. It has significant advantages in relation to reduce costs, save energy and improve efficiency. However, the general supercharger also has the shortcomings of complex structure, maintenance inconvenience and outleakage. The self-oscillation jet devices have the advantages of small size, simple structure, no additional driver outside the body and no dynamic seal etc. It has better erosion effect than continuum jet, so it is a promising jet devices. It's application to the line supercharger can save production costs, reduce energy consumption, so that the issue accordance with the actual needs uses the self-oscillation pulse jet into the application of pipeline supercharger for the first time and gets a good result from simulation test.This paper carries out simulation and analysis on the supercharging effect caused by self-oscillation of different parameters of the structure by finite element analysis. First of all, the formation of self-oscillation is researched and the principle that self-oscillation can be used for pipeline supercharger is found, then the self-oscillation structures combined with the fluid network theory, calculation of the natural frequency, resonance conditions and Large Eddy Simulation Theory was designed, and a series of pipeline superchargers was gotten. In this paper It has been introduced that the flow field simulation to the self-oscillation cavity of the pipeline supercharger based on the Self-oscillation Theory with the help of ANSYS. Combined with the structure predigestion and the borderline disposal, the research deduces the 3D-flow field of the pipeline supercharger. According to the distributing chart of the flow field and the pressure, the press curve that varies with the parameter is plotted and the influence of the structure parameter to the press-increasing effect is validated and the reference to the optimization design is. provided. It does analysis for the quiver characteristic and provides the beneficial reference for fault diagnosis and dynamic design of the pipeline supercharger. Combined with the theoretical study and the other scholars' test process, analysis results, it shows that the use of self-oscillation in the pipeline supercharger is feasible.
