以综合性能较好的氧化镁固体为例,并在保证一定开孔率的前提下,分别在其中开设不同孔数的圆形或方形孔道进行蓄热以及以空气为介质的放热特性分析;通过数值计算得出了蓄热体达到稳定时的蓄热时间,以及在放热过程中放热介质的温度、压力及换热量随孔数和换热时间变化而变化的规律。

Adopting Solid MgO of good function as an instance,guaranteeing the least number of round poles,the paper,through numerical calculation,conducts the characteristic analysis of heat storage with a different number of round or square pore canals and heat release with the medium of air.It comes to the conclusion about the regenerative time for heat storage media getting sta-ble and the temperature and pressure of heat release media while releasing heat as well as the relations between the number of poles and the duration of heat release.
