NONEQUILIBRIUM MULTIPHASE DYNAMIC PROCESSES IN POROUS MEDIA

B. Draganov, A. Dolinsky

 

The processes of heat exchange in multiphase porous medium occurring in many plants. Therefore it is important to establish the laws of these processes.

The purpose of research - to develop a method of analysis of the dynamics of adsorption processes in a porous medium.

We consider a heterogeneous system consisting of several homogeneous parts, each of which contains a certain mass. In accordance with the Gibbs free energy equation is obtained, which is performed in any homogeneous part of the system.

process of heat and mass transfer analysis was performed by the above medium in a porous body.

The dynamics of the stream, you can take two-dimensional. Main characteristics of the fluid - the density and temperature vary according to the linear relation Boussinesque.

 

Conclusions

The energy processes often take place the processes that accompany phase changes. A special role they play in the adsorption thermotransformers. The paper presents a method for analyzing the process of heat transfer medium in a multiphase porous medium.
