Experimental Study on Influence of Orifice Plate Water Distribution Structure on Thermal Storage Performance
A cylindrical thermal storage water tank with orifice plates above and below is taken as the research object,and a thermal storage performance ex-perimental platform is constructed for the thermal stor-age water tank.Multiple operational conditions are de-signed,the thickness of the thermocline is used as the evaluation index to study the influence of pore plate water distribution structure parameters(hole area ratio and number of holes)on thermal storage performance.Placing orifice plates in the heat storage water tank can effectively prolong the duration of the thermocline dur-ing the heat storage process and reduce the thickness of the generated thermocline.For both single hole and porous hole plate schemes,the optimal ratio of opening area is 0.2.
