Optimisation for interconnected energy hub system with combined ground source heat pump and borehole

Da HUO, Wei WEI, Simon Le BLOND

Frontiers in Energy 2018, Volume 12, Issue 4,   Pages 529-539 doi: 10.1007/s11708-018-0580-0

Abstract: Ground source heat pumps (GSHP) give zero-carbon emission heating at a residential level. However, as the heat is discharged, the temperature of the ground drops, leading to a poorer efficiency. Borehole inter-seasonal thermal storage coupled with GSHP maintains the efficiency at a high level. To adequately utilize the high performance of combined GSHP and the borehole system to further increase system efficiency and reduce cost, such a combined heating system is incorporated into the interconnected multi-carrier system to support the heat load of a community. The borehole finite element (FE) model and an equivalent borehole transfer function are proposed and respectively applied to the optimisation to analyze the variation of GSHP performance over the entire optimisation time horizon of 24 h. The results validate the borehole transfer function, and the optimisation computation time is reduced by 17 times compared with the optimisation using the FE model.

Research Status and Development of the Bowed-Twisted Blade for Turbomachines

Wang Zhongqi,Zheng Yan

Strategic Study of CAE 2000, Volume 2, Issue 6,   Pages 40-48

Abstract:

The bowed-twisted blades have been widely used in the developed countries in the 1990s, such as the USA and UK. In China, this new type blades are also successfully applied to the steam turbines, and the application of these blades to gas turbines of air-engines has had a good beginning. The effectiveness of applying the bowed-twisted blades to turbines demonstrated by the tunnel and static experiments is discussed, and the mechanism of reducing the radial-and cross-secondary flow losses by using the bowed-twisted blades is analyzed in this paper. The advances in research on compressor bowed blades and key problems in this research are considered shortly. Based on design experiences, several principles for designing stages with bowed-twisted blades are summarized in the end of this paper.
