Experimental Investigation of Heterogeneous Power Systems on the Basis of Lyophobic Liquids and Porous Media
Engineering Education # 05, May 2014
DOI: 10.7463/0514.0711242
A mathematical model of the liquid flow in heterogeneous systems is developed. Heterogeneous systems consist of a porous body with the pore size from 20 nm to 360 nm and a lyophobic (non-wetting) liquid. The paper represents theoretical basics to describe a hysteresis of liquid filling and outflow processes from the pores under the pressure gradient, and also with no liquid outflow after reducing a pressure in the system to the atmospheric value under static and dynamic loads. The paper presents experimentally investigated and calculated results of the energy characteristics of models of the heterogeneous dissipation and accumulating devices of mechanical energy developed on the basis of abovementioned effects.
