换热关联式中流体定性温度的确定

Determination of Fluid Qualitative Temperature in the Relational Formula of Heat Exchange

在介绍两种常见边界条件下流体定性温度确定方法的基础上,提出了一种用积分平均温度确定流体定性温度的方法,这种方法对确定进出口温差比较大的流体物性有更高的精确度。

This paper presents a way to determine fluid qualitative temperature with integral average temperature, based on methods on two kinds of common boundary conditio- ns. This new way has greater accuracy of determining fluid property when fluid temperature difference between inlet and outlet is great.
