Abstract Compliant thermoelectric generators (TEGs) hold great promise in the field of self‐powered wearable electronics. Yet, low heat transfer efficiency arising from large thermal resistance between elastic encapsulating materials and contacted objects severely lowers thermopower. This issue is much more challenging for organic TEG ( o TEG) due to high parasitic loss whole polymer system. Herein, guided by finite element analyses, a polydimethylsiloxane based composite coated with Cu...
Abstract With the increasing attention to clean and economical energy resources, geothermal enhanced systems (EGS) have gained much importance in recent years. For efficient development of deep reservoirs, it is crucial understand mechanical behavior reservoir rock its interaction with injected fluid under high-temperature high confining pressure environments for employing hydraulic stimulation technologies. In present study, we develop a novel numerical scheme based on distinct element...
Abstract With the increasing attention to clean and economical energy resources, geothermal enhanced systems (EGS) have gained much importance. For efficient development of deep reservoirs, it is crucial understand mechanical behavior reservoir rock its interaction with injected fluid under high temperature confining pressure environments. In present study, we develop a novel numerical scheme based on distinct element method (DEM) simulate failure by considering influence thermal stress...
We developed a new multi-component sensor based on distributed acoustic sensing (DAS) technology for seismic exploration. A prototype DAS is designed to independently record 3D vectorial wavefield, i.e., x-, y- and z-components, consisting of an optical fiber wound around polyvinyl chloride frame. conducted field experiment evaluate the performance sensor. The observed wavefield by compared with those conventional geophones. observation results indicate that each component has its own...
ABSTRACT With the development of reservoir stimulation technology, more and deep shale reservoirs (>4000m) have become targets gas exploitation. In order to better understand performance in environment, we carry out a series high-temperature high-pressure experiments on Longmaxi shale. A thermal-mechanical coupled model for anisotropic rocks is then proposed based discrete element method (DEM). The thermal behaviors are implemented by introducing expansion algorithms, while...
In the present study, we investigate thermal effect on physical and mechanical properties of rock mass using numerical experiments based discrete element method (DEM) to understand influence treatment process in geothermal reservoir rocks. We propose a new thermal-mechanical coupling model for DEM focus cooling under various confining pressure. After verifying proposed by comparing results with those laboratory temperatures, uniaxial compression tests different processes are conducted. apply...
