在各种热学教材及参考书中,求卡诺循环的效率都是以特殊的工作物质——理想气体来研究的,同时利用卡诺定理,即在相同的高温热源和相同的低温热源之间工作的一切可逆热机,其效率都相等,与工作物质无关,与可逆循环的种类也无关,得到了任意实际气体在准静态过程中的卡诺效率.
实际上,热机的工作物质一般都不是理想气体,那么实际气体的卡诺循环效率应满足什么关系,对于非理想气体是否仍遵守关系式.现以范德瓦尔斯气体为工作物质推导出非理想气体的卡诺循环效率,比较是否与理想气体卡诺循环的效率相同,进一步来证明卡诺定理的正确性.
Textbooks and reference books in a variety of thermal, seeking the efficiency of the Carnot cycle are studied with a special material - ideal gas Carnot theorem, that is in the same high-temperature heat source and the same low temperature heat sourcethe work of all reversible heat engine, its efficiency is equal to nothing to do with the work material has nothing to do with the type of the reversible cycle, any real gas Carnot efficiency in the quasi-static process.
In fact, the heat of the working substance is generally not an ideal gas Carnot cycle efficiency of the actual gas should satisfy the relationship, and still comply with the non-ideal gas relationship. Now derive the non-ideal gas Carnot cycle efficiency as the working substance to the van der Waals gas, compare the same with the ideal gas Carnot cycle efficiency and further to prove the correctness of the Carnot theorem.
