摘要
通过对超临界二氧化碳管内流动及换热特性研究现状和分析方法介绍,列出常用的超临界二氧化碳在不同条件下的传热和压降关联式,进一步说明自然工质二氧化碳的跨临界循环特点和所具有的独特的热物理性质,指明超临界二氧化碳的利用和新型换热设备的研发方向。
Through introducing present study and analysis methods of supercritical carbon dioxide flow and heat transfer in tube, listing some recognized correlations for heat transfer coefficient and pressure drop during in tube heating and cooling, further confirming the characteristics of supercritical carbon dioxide flow and heat transfer in tran-critical cycle system, then showing the direction for the use of supercritical carbon dioxide and invention of new heat transfer equipment.
