Unsteady pressure-pulsation-induced severe vibration and high alternating stress can cause some unexpected results, including impeller crack structural damage of the entire pumping system. In present paper, a review on pressure pulsations in pumps is carried out based published studies. A comprehensive view from several aspects discussed detail. The contents studies include mechanism rotor–stator interaction; prediction model experimental numerical investigations pulsations; unsteady...
This paper presents an improved empirical modal decomposition (EMD) method to eliminate the influence of external environment, accurately compensate for temperature drift MEMS gyroscopes, and improve their accuracy. new fusion algorithm combines mode (EMD), a radial basis function neural network (RBF NN), genetic (GA), Kalman filter (KF). First, working principle newly designed four-mass vibration gyroscope (FMVMG) structure is given. The specific dimensions FMVMG are also given through...
Several giant oilfileds have been discovered during recent exploration in the Ordovician carbonates zone between Awati and Manjiaer depressions, Tarim Basin, China. These oilfields are deeply buried (>7000 m), most productive wells found adjacent to fault zones, suggesting faults may play a crucial role reservoir development. Here, we use petrographic, microanalytical geochemical techniques on different stages of void-filling calcite cements decipher tectonic-fluid evolution history. Vugs...
Considering the complicated interactions between temperature, pressure and hydration reaction of cement, a coupled model temperature based on kinetics during deep-water well cementing was established. The differential method used to do numerical calculation, calculation results were compared with experimental field data verify accuracy model. When are considered, proposed is within 5.6%, which can meet engineering requirements. A series simulation conducted find out variation pattern degree...
The past decade has witnessed a breakthrough in the gas exploration of deep marine carbonates central Sichuan Basin. Deep faults research also attracted increasing attention, as faulting plays an important role reservoir control. Previous studies have suggested developed series high-angle strike-slip fault systems Basin, but correlated activities are limited, distribution rules and dynamic mechanisms remain unclear. In this study, spectral decomposition coherence method was used to describe...
Rock mechanics parameters are crucial factors for predicting rock behavior in oil and gas reservoirs, optimizing extraction strategies, ensuring drilling safety. In this study, we propose a random forest (RF)-convolutional neural network (CNN)-long-term short-term memory (LSTM) fusion model based on the dynamic time warping (DTW) algorithm to construct intelligent prediction models elastic modulus, Poisson’s ratio, compressive strength using real-time engineering data. An autoencoder with...
As the critical component of a nuclear power plant (NPP), reactor coolant pump (RCP) will suffer energy losses during operation, which can lead to series safety issues and adversely affect efficiency stability NPP. In this study, SST k-ω turbulence model is utilized simulate internal flow field an axial-flow under operating conditions 0.8QN 1.2QN. Combined with entropy production theory, distribution characteristics hydraulic causes loss within different regions RCP are revealed. The...
A novel high-efficiency cooling mini-channel heat-sink structure has been designed to meet the package technology demands of high power density laser diode array stacks. Thermal and water flowing characteristics have simulated using Ansys-Fluent software. Owing increased effective area, this a better effect when compared with traditional macro-channel heat-sinks. lower flow velocity in efficient structure, chillers' water-pressure requirement is reduced. Meanwhile, machining process simple...
