In the process of the exploitation of heavy oil, the energy loss of well bore directly affects the effect of steam injection thermal recovery, reasonable thermal calculation model of stream injection well bore is important for establishing the surface energy of well bore. There are already many calculation models about well bore energy loss, however there are still shortcomings of the application...
Based on the properties of conventional cyclic water gathering process, the key question of energy saving was attained. A novel cyclic water gathering process was introduced according to the thermal short circuiting theory of borehole heat exchanger in the ground. Energy conservation calculation model was proposed. And the conservation calculations of system were studied using model. The results show...
The secure shutdown time of submarine oil pipeline must be determined before pipeline designed and put into production. Considering the actual operation situations, physical model of heat transfer was established for submarine oil pipelines, and experimental equipment of submarine oil pipelines with shutdown and heat transfer was designed based on the similarity theory. It can simulate the shutdown...
In the process of the exploitation of heavy oil, the energy loss of the ground steam pipelines directly affects the effect of steam injection thermal recovery, reasonable calculation model is important for establishing the surface energy of the steam pipelines. There are already some calculation models about the ground steam pipe energy loss, however there are still shortcomings of the application...
High error in calculating the heat transfer of floor heating system can be introduced by existing models, considering the heat transfer of the floor slab and different temperature between interior wall and exterior wall. A modified calculation model of heat transfer of floor heating system was proposed, analyzed the influence of the interior or exterior wall and the floor slab, and discussed the disadvantages...
Features of the I-V characteristics and the electrical properties of electronics-grade carbon nanotube (EG-CNT) sensors, which were fabricated and integrated in micro fluidic system by combining MEMS-compatible fabrication technology with AC dielectrophoresis technique, were investigated at room temperature to account for significant Joule heating effect under high activation current. The experimental...
