  heat transfer processes
When the nonuniformities in the imposed temperature differences are increased, large deformations of the liquid-vapor interface occur that lead to an enhancement of the heat transfer processes.

A macroscopic model of the diffusion and heat transfer processes in a periodically micro-stratified solid layer
      
The analysis of the obtained results showed that the flow field is appreciably influenced by the viscosity/temperature parameter, and hence care must be taken to include the variation of viscosity with temperature in the heat transfer processes.
      
In particular, it is concluded that when the viscosity of a working fluid is sensitive to the variation of temperature, care must be taken to include this effect, otherwise considerable error can result in the heat transfer processes.

This anticle introduces a more aceurate calculating method for the down-film absorber, a main apparatus in the NH_3 absorp tion refrigerating machine. The absorption of NH_3 is both a mass transfer and a heat transfer process. In the process,the temperature of the absorbing solution is not uniformly decreased by cooling. So it is necessary to divide the tube into many small segments in length, and calculate the absorption and heat transfer rate of the segment one by one, until the...

This anticle introduces a more aceurate calculating method for the down-film absorber, a main apparatus in the NH_3 absorp tion refrigerating machine. The absorption of NH_3 is both a mass transfer and a heat transfer process. In the process,the temperature of the absorbing solution is not uniformly decreased by cooling. So it is necessary to divide the tube into many small segments in length, and calculate the absorption and heat transfer rate of the segment one by one, until the required absorbing degree of the NH_3 has been reached. Thus the number of segments,the lenth of the tube and the area of absorber can be determined. Comparing the area obtained simply by LMT heat transfer method with the area obtained by the aforesaid method, the latter is much smaller than the former. The way to enhance the heat transfer of the tube, in order to shorten the size of the absorber, is also presented in this article.

本文论述了氨吸收制冷中主要设备降膜式吸收器较为精确的计算方法。由于氨吸收过程为强放热过程,故既有传质过程,又有传热的过程。因为吸收过程溶液的温度不是均匀下降的,故其所需传热面积不能采用一般的平均温度差来计算,而需将管子按长度分为许多微小段,逐段进行吸收和传热计算.求出直到将全部氨气负荷吸收时所需的段数和管长,即求出了设备所需的面积。用对数温度差传热方法计算的设备面积比用逐段传热传质计算所得的结果要大得多。文中还提出了强化传热的措施,以提高设备效率。

By managing the heat conduction problem in solids the thermal conductivity is usually taken as a constant, but in reality varying thermal conductivity reveals in every heat transfer process. Therefore, in the present paper, we wish to consider it to vary with the space coordinate according to a linear and an exponential law; basing on this proposal we have been able to set up six second order heat conduction differential equations. By the way, for the case of variable density, specific heat...

By managing the heat conduction problem in solids the thermal conductivity is usually taken as a constant, but in reality varying thermal conductivity reveals in every heat transfer process. Therefore, in the present paper, we wish to consider it to vary with the space coordinate according to a linear and an exponential law; basing on this proposal we have been able to set up six second order heat conduction differential equations. By the way, for the case of variable density, specific heat as well as thermal conductivity, we have been successful to deduce other similar six heat transfer differential equations.
