Normalized value of air specific heat capacity ratio and the errors in measurement

空气比热容比的标准值与测量的误差

The entropy generation number N st of heat exchangers of several flowing pattern was compared with that of contraflow heat exchanger. The varying law of N st with the heat transfer unit number NTU, inlet temperature ratio τ and heat capacity ratio C was obtained.

将几种流动型式换热器相对于逆流式换热器进行了熵产生数相对值的比较，得到了熵产生数相对值随传热单元数、入口温度之比和热容量之比的变化规律。

Using FD-NCD air specific heat capacity ratio determinator, the universal gasconstant and Boltzman constant were measured based on the phase transition method.
