چکیده
Temperature is one of the main loads super-high arch dams. (1) Background: a dam in southwest China was taken as an example this paper and temporal-spatial evolution law temperature analyzed based on monitoring data. (2) Methods: finite element simulation analysis method adopted to invert boundary conditions upstream surface thermal parameters concrete, process long-term operation simulated analyzed. After distribution characteristics designed reservoir water actual were compared, difference field during impoundment under studied. (3) Results: period accords with conventional knowledge, calculated value through feedback good agreement value, which can reflect dam. (4) Conclusions: design condition, rose slowly after closure grouting then tended be stable. Under by 7.1~9.2 °C grouting, reached highest about 8~12 years, fell back stable 40~80 years.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
The Numerical analysis of an anode-supported high temperature DIR-PSOFC operating conditions with considering the maximum allowable temperature difference
In the present study, the operating conditions of an anode-supported high temperature direct internal reforming (DIR) planar solid oxide fuel cell (SOFC) are numerically analyzed. SOFCs are the energy conversion devices that produce electricity and heat directly from a gaseous fuel by the electrochemical combination of that fuel with an oxidant. A planar SOFC consists of an interconnect structu...

15 صفحه اولHigh-Temperature Stable Operation of Nanoribbon Field-Effect Transistors
We experimentally demonstrated that nanoribbon field-effect transistors can be used for stable high-temperature applications. The on-current level of the nanoribbon FETs decreases at elevated temperatures due to the degradation of the electron mobility. We propose two methods of compensating for the variation of the current level with the temperature in the range of 25-150°C, involving the appl...
