A heat–fluid–solid coupling method was established to calculate the flow and stress fields, changes in temperature pressure fields erosion stresses on aluminum surfaces under 100 MPa submerged water jets were studied. The results show that impact is key factor affecting area jet angle viscous dissipation. can produce an of 80 °C, above 70 °C more than ten times MPa. maximum tensile shear temperature–pressure field are 1.5 6 field, respectively. Under will not be destroyed, while...
In previous studies it has been shown that supercritical carbon dioxide (SC-CO2) jets are more efficient at rock breaking than water jets, but the corresponding systematic mechanism explanations were not available. Therefore, this paper conducts an in-depth analysis of fluid properties with equations suggested by American National Institute Standards and Technology (NIST), establishes fluid-solid-heat coupling model support ANSYS, reveals stress responding SC-CO2, nitrogen jets. When is room...
Abstract The supercritical carbon dioxide (SC‐CO 2 ) jet is a new‐type of rock‐breaking method that effectively combines pressure impact and thermal shock. Current studies show produces larger damaged area requires lower threshold for rock breaking compared to water jet; however, the mechanism SC‐CO has not been clearly explained. This study developed heat‐fluid‐solid coupling model using ANSYS. simulation experimental results good agreement, explaining effect stress in jet. shows...
Abstract To reduce near wellbore fracture complexity in continental laminated shales, in-plane perforations completion technology is introduced. The global embedded cohesive elements are capable to simulating arbitrary propagation growth while the laminae effects on path can be considered established finite element model. Numerical simulations reflect that existence of weak micro fractures only locally alter but change greatly. Furthermore, in-situ stress anisotropy, pump rate, perforation...
In view of the problems that most load forecasting methods are difficult to achieve high-precision data processing in process power grid digitization, a digital method based on twin and improved GRU is proposed. Firstly, model constructed technology, operation mode introduced detail. Then, time convolution network (TCN) gated recurrent unit (GRU) fused design GRU-TCN prediction model. The high-dimensional features extracted by TCN input into for learning enhance performance. Finally, applied...
Aiming at the problem that traditional power flow coordination and optimization methods are difficult to apply situation a large number of Distributed Generations (DG) connected can′t effectively control flow, Coordination Optimization Control(COC) method based on Deep Reinforcement Learning (DRL) for Power Grid (PG) with DGs is proposed. Firstly, influence DG grid connection Distribution Network node voltage distribution analyzed, JFNG algorithm used calculate distributed considering DG....
CO2 is a potential fluid for absorbing and accumulating thermal energy; an accurate fast calculation method the heat capacity essential study of flow state near critical point. However, point by equations suggested NIST can easily be divergent, such as CO2, nitrogen, methane, etc. Therefore, explicit fitting equation was studied. The equation, which used density temperature variables contained three constants, derived from nature change (molecular kinetic energy energy). Based on data...
In order to cure the crux of low accuracy traditional PG transient stability prediction (PGTSP) methods, a PGTSP method based on improved Convolutional Neural Network(CNN) is proposed under big data.
