稳定流动干绝热递减率的研究

Research Analysis and Modification of Oil Heater of Refrigeration Unit

经过分析和推导,发现"干绝热递减率"在实际应用中有一定的局限性。本文在此基础上,根据空气流动的不等速性,运用稳定流动方程重新推导了更具有普适性的干绝热递减率公式,称为稳定流动干绝热递减率。并分析了两个干绝热递减率的区别和联系,有一定的理论意义。

Through analysis and deduction, it found that the “dry adiabatic lapse rate” theory has certain limitations in the application. On the basis, according to the performance of different speed of airflow and using the steady-state flow equation, a more universal “dry adiabatic lapse rate” theory is induced, called the steady-state flow “dry adi-abatic lapse rate” theory. Besides, this paper analyzes the differences and relationship of these two theories. In some certain, it has theoretical significance.
