Abstract:The grounds for further fundamental study of heterogeneous lyophobic systems (HLS) under technical thermodynamics in order to create nontraditional high-performance thermo-mechanical devices (dampers, accumulators and energy converters) are presented. A number of unusual HLS properties have been analyzed in view of their practical use: nontypical for conventional working bodies (gas, vapor) compression/decompression endo-/exothermal effects; operational features under adiabatic and cycling conditions. Thermodynamic model describing HLS behavior under conditions that are useful for operational requirements of technical devices and systems is proposed.

Correlation effects arising during liquid infiltration into hydrophobic porous medium are considered. On the basis of these effects a mechanism of energy absorption at filling porous medium by nonwetting liquid is suggested. In accordance with this mechanism, the absorption of mechanical energy is a result expenditure of energy for the formation of menisci in the pores on the shell of the infinite cluster and expenditure of energy for the formation of liquidporous medium interface in the pores belonging to the infinite cluster of filled pores. It was found that in dependences on the porosity and, consequently, in dependences on the number of filled pores neighbors, the thermal effect of filling can be either positive or negative and the cycle of infiltration-defiltration can be closed with full outflow of liquid. It can occur under certain relation between percolation properties of porous medium and the energy characteristics of the liquid-porous medium interface and the liquid-gas interface. It is shown that a consecutive account of these correlation effects and percolation properties of the pores space during infiltration allow to describe all experimental data under discussion.

Research and development of new materials with high energy dissipation density is one of the key approaches to promote the automotive crash safety. [1,2] Conventional energy dissipation materials and structures based on metal plastic deformation, [3] buckling of cellular truss or foam, [4] damping of polymers, [5] internal friction of textile composites, [6] and phase transformation [7] are employed to achieve the energy desired dissipation goal. Most materials developed so far, however, have relatively low energy dissipation performance in terms of the unit mass/volume consideration, and most of them are not reusable. Therefore, reusable, high-density energy dissipation material candidates are in pressing need for industries.Nanomaterial is considered and proven to be a promising alternative to these traditional materials, [8][9][10][11] among which an innovative nanoporous material energy absorption system (NEAS) was recently established [12] where a nanoporous material and liquid are combined with controllable wetting properties. In essence, NEAS takes advantage of the ultralarge surface area of nanoporous material and during the liquid infiltration process, it converts the external mechanical energy into the excessive solid-liquid interfacial energy and frictional heat. The wetting characteristic, which dominates the infiltration/defiltration and flow behaviors of liquid molecules, can be adjusted via various approaches, including COMMUNICATIONInteraction with liquids at the ultra-large surface area of nanoporous material enables a high-efficiency energy dissipation system with wide perspective applications [A. Han, et al., Langmuir 2008, 24, 7044]. In this paper, a nanoporous energy dissipation system composed of a mixture of zeolite ZSM-5 and water is established and studied experimentally. Firstly, quasi-static compression experiments are carried out to analyze the pressure-volume curve and reveal the energy dissipation mechanism. Afterwards, a parametric study is conducted to explore the effects of three parameters, the pretreatment temperature of zeolite ZSM-5 (600-1100 8C), mass ratio of ZSM-5 to water (1:5-6:5), and average zeolite particle size (2.145-5.251 mm before heated or 6.104-9.557 mm after heated). Results show that in order to obtain optimum energy absorption performance, the pretreatment temperature of about 1000 8C, and higher ratio of ZSM-5 with larger particle size are desired. With high energy dissipation and reusability, the zeolite-water system with optimal parameters established herein may become an attractive cushioning device. 740 wileyonlinelibrary.com ß
