  conductive heat
Neglecting conductive heat transfer, it is shown that for the model in question in the plane of the complex potential not only are the problems linear but the decoupling of the thermal and hydrodynamic problems is also allowed.
      
A self-similar solution describing the heat and mass transfer processes associated with radiative-conductive heat exchange between the walls of a plane channel and evaporation from one of the walls is obtained.
      
Calculation of channel flow with wall evaporation induced by radiative-conductive heat transfer
      
Below, a flow model and a method of calculating the flow in a narrow plane channel of finite length in the presence of evaporation or sublimation on one wall induced by radiative-conductive heat transfer from the other hot wall are proposed.
      
These flows are due to the effect of the heat-release source, the propagation of perturbations induced by elements of the rigid wall, and the dynamics of conductive heat transfer in the solid material.

Despite the lacking in observed conductive heat flows, an attempt has been made to divide the upper crust with depth up-to 10 km of the whole Xizang Plateau into superthermal, thermal and the normal states according to the hydrothermal manifestations omnipresent there and their quite different characteristics. The superthermal zone is present between the Himalayas and the Kangdese-Nyainqentanglha. This is the Himalayan Geothermal Belt. The thermal zone is located in the southern part of the Zangbei (Northern...

Despite the lacking in observed conductive heat flows, an attempt has been made to divide the upper crust with depth up-to 10 km of the whole Xizang Plateau into superthermal, thermal and the normal states according to the hydrothermal manifestations omnipresent there and their quite different characteristics. The superthermal zone is present between the Himalayas and the Kangdese-Nyainqentanglha. This is the Himalayan Geothermal Belt. The thermal zone is located in the southern part of the Zangbei (Northern Tibet) Plateau, while the northern part of this plateau is in the normal zone. Althougth a volcanic eruption occurred in the northern margin of the latter zone at 27 Oct. 1951, the chemistry of its lava suggests that it did not originate from intracrustal melting and the upper crust of the northern part of Zangbei Plateau might not be hot.

本文在缺乏传导热流量实测数据的情况下,试图根据遍布高原上的水热活动显示及其南部的板缘水热活动性质,将西藏高原上地壳深10公里的厚度内划分为高热、热和一般等三种状态。高热带位于喜马拉雅山以北至冈底斯-念青唐古拉山以南之间,这就是所谓的喜马拉雅地热带。热带位于藏北高原的南半部,它的北半部被划为一般正常带,其北缘昆仑山中虽于1951年有过火山喷发,但岩浆性质说明它并非来源于壳内熔融,因此上地壳未必是热的。

The crustal temperature distribution and conductive heat flows of the Himalayan region were estimated by non-linear finite element method.There are different crustal temperature structures in the Himalayan region. The temperature contour lines on the south of the Himalayan mountain range are relatively even and the conductive heat flows are less than 1.5 HFU, whereas on the north, the distribution of contour lines are clearly concentrated from the earth surface to 20 km depth. However, the contour...

The crustal temperature distribution and conductive heat flows of the Himalayan region were estimated by non-linear finite element method.There are different crustal temperature structures in the Himalayan region. The temperature contour lines on the south of the Himalayan mountain range are relatively even and the conductive heat flows are less than 1.5 HFU, whereas on the north, the distribution of contour lines are clearly concentrated from the earth surface to 20 km depth. However, the contour lines below 20 km are circularly distributed. The conductive heat flows on the north of Himalayan mountain range are from 1.5 HFU to 2.1 HFU.Based upon the analysis of the distribution of the temperature contour lines, a possible partial melting area has been drawn in the southern part of Xizang plateau and the result of this analysis ha,s been compared with those obtained from other geological and geophysical data.

本文考虑放射性热源,采用非线性稳态有限单元法估算了喜马拉雅地区地壳的温度分布和地表热流值。 喜马拉雅山南、北有不同的地壳温度结构,南部等温线比较均匀,地表热流值低于1.5HFU;北部地表下20公里以上等温线成密集型分布,20公里以下成环状分布,地表热流值从1.5HFU至2.1HFU。根据等温线圈出西藏南部地区地壳内可能存在局部熔融的部位,并与其他地球物理资料作了比较。

In tnis paper an analytical method is proposed to predict the distribu-tion of the rate of entropy generation per unit volume in the boundary layer by means of the simultaneous solution of continuity, momentum, energy and entropy differential equations. Air is taken as an example to investigate the effects of the local Reynolds number, the Eckert number and the ratio of characteristic temperature difference to wall temperature on the distribution of the entropy generation in laminar boundary layer along a flat plate. In addition, the rules that govern the change of entropy generation by conductive heat transfer and viscous dissipation are also discussed in this paper.This paper may offer some aids to understand the mechanism and the distribution of entropy generation as well as to overcome the irreversibility so as to provide menas for fully-utilizing the energy in the process of convective heat transfer.

本文通过连续方程、动量方程、能量方程和熵方程的联立求解,对于对流换热边界层内单位体积熵产生率的分布,提出了一种计算方法。并以空气为例,研究了局部雷诺数、爱克特数和特性温差与壁面温度比对平板层流边界层内熵产生率分布的影响。还分别对传热熵产生率和粘性耗散熵产生率的变化规律作了分析。 本文对了解对流换热过程中熵产生的机理及其分布情况,改善该过程的不可逆性和节约有用的能量等方面,有一定现实意义。
