The Performance of Bubble Pump Applied on Solar Water Heater

The performance of bubble pump was discussed in this paper. First, this article gave a brief introduction of solar water heating system and bubble pump. It explained the research background. In the second chapter, the theoretic foundation of bubble pump, which refer to two-phase flow and heat transfer in boiling was given. Based on this, commend a structure of bubble pump. In the third chapter, by the numerical simulation to design the optimize dimension of bubble pump. In the forth chapter, involves the testing of bubble pump solar water heating system. Four sub-chapters included short-term results and analysis, long-term result and analysis. At the meantime, because of thε quarter application difference, the comparative analysis of winter and summer running condition was given. Final1y, give the comparative analysis with the reference. The last chapter is the conclusion part of this thesis.
