Aiming at the problems of high grain entrainment loss rate and impurity traditional horizontal axial-flow combine harvesters, a threshing-separating device with coaxial differential threshing drum, conical cleaning fan, double-layer vibrating screen spiral plate-tooth re-thresher is designed. Meanwhile, test-bed feeding 2 kg/s designed to improve performance. The test through quadratic orthogonal rotation combination design method used inspect effects drumspeed combination, fan blade taper,...
Coal, as a heterogeneous porous medium, exhibits substantial adsorption capacity for coalbed methane, highlighting the necessity to comprehend methane storage mechanisms reserve evaluation and production optimization. To investigate characteristics of novel approach calculating thermodynamic parameters is developed based on phase equilibrium fugacity principles. Isothermal experimental results are utilized assess influence moisture mechanism, disclosing variations in enthalpy, entropy, Gibbs...
When developing weakly consolidated reservoirs by horizontal wells and facing the problems of sand production water breakthrough, a poor understanding particle-water-oil transport interaction mechanisms in porous media can seriously affect comprehensive benefits well production. In this paper, an unresolved discrete element method-volume fluid (DEM-VOF) coupling method is proposed for oil-water two-phase flow containing fine particles within pore-scale media. The characterized calculation...
Abstract Hole cleaning is one of the key issues in extended reach drilling, thickness cutting bed monitor and control critical technique which urgent to solve. Based on solid-liquid flow mechanics, considering actions between layers, slip solid liquid phase, rotation drill pipe, a three layer dynamic transport model was developed, staggered mesh Stability Enhancing Two Step method were adopted for simulation. The influence factors analyzed, ECD with variable can be accurately predicted, by...
Summary As an efficient method for hard rock fracturing, rotary-percussive drilling has been widely used in various scenarios, especially deep drilling. Drilling parameter monitoring and control are necessary to ensure stable underground processes. However, this may be more difficult deep, harsh conditions. In paper, our goal is establish models based on learning optimization. Combining impregnated diamond bits granite samples, we conducted experiments using a test rig. Real-time acoustic...
Considering the special wellbore configuration and operating environment of deep-water drilling, a comprehensive model for circulating pressure loss drilling is established. Based on fluid mechanics theory heat transfer theory, temperature riser section are calculated coupling approach proposed. Comprehensive factors that affect considered in this study. These mud properties, flow regime, drill pipe rotation, eccentricity, cuttings bed, tool joints, BHA (Bottom Hole Assembly), bit surface...
In view of the complex constraints ships choosing entry and exit channels, which are likely to cause ship congestion low efficiency, support vector machine algorithm is used establish a classification model suitable for navigation channels realize decision-making management control channels. By deleting missing values irrelevant features AIS data, eight related factors size sailing state were selected as input variables machine, two-classification waterway based on SVM was established. Using...
