Abstract The molecular structure‐editing through selective C−C bond cleavage allows for the precise modification of structures and opens up new possibilities in chemical synthesis. By strategically cleaving bonds editing structure, more efficient versatile pathways synthesis complex compounds could be designed, which brings significant implications drug development materials science. o ‐Aminophenethyl alcohols amines are essential key motifs bioactive functional material molecules....
Grinding circuit must provide stable particle size distribution and should also operate in a way to maximize mill efficiency. Fuzzy logic based on-line optimization control integrated an expert system was developed product while enhancing efficiency ball grinding circuit. In the supervisory level, fuzzy determined optimum set-points for controllers regulatory level. The whole not only ensured long-term stableness of even ore hardness has changed but increased more than 8 percent practical...
Abstract To simulate the centrifugal short‐path distillation process, both two phases and interfacial transport are taken into account simultaneously for first time. A new computational fluid dynamics model based on volume‐of‐fluid species methods is built up to analyze detailed flow transfer characteristics. binary system with dibutyl phthalate‐dibutyl sebacate (DBP‐DBS) used as an example investigation numerical experimental methods. The residence time effects of operating parameters such...
A deterministic-stochastic coupling scheme is developed for simulating rarefied gas flows, where the key process alternative solving of macroscopic synthetic equations [Su et al., J. Comput. Phys., 407 (2020) 109245] and mesoscopic equation via asymptotic-preserving time-relaxed Monte Carlo [Fei, 486 (2023) 112128]. Firstly, are exactly derived from Boltzmann equation, incorporating not only Newtonian viscosity Fourier thermal conduction laws but also higher-order constitutive relations that...
The shock wave and boundary layer interaction (SWBLI) plays an important role in the design of hypersonic vehicles. However, discrepancies between numerical results high-temperature gas dynamics experiment data have not been fully addressed. It is believed that rarefaction effects are SWBLI, but systematic analysis temperature-jump conditions translational/rotational/vibrational heat conductivities lacking. In this paper, we derive three-temperature Navier-Stokes-Fourier (NSF) equations from...
Abstract This paper proposes a novel two-axis solar tracker with redundant parallel mechanism and investigates the distribution method of driving torque. In view difference between singular configuration mechanisms that corresponding non-redundant ones, an index related to minimum value Jacobian matrix is used indicate position relative boundaries required workspace. The torque energy consumption can be optimized this index. Based on fact direction opposite rotor in most running processes,...
Transformable robots are attracting increasing interest because of their ability strong environmental adaptability. In this paper, a double-body car-snake hybrid transformable robot with flexible movement and adaptability was developed to meet the needs automatic inspection in complex industrial environments. A special connecting rod aid digital steering gear designed for robot, which enables it quickly switch between car-shaped snake-shaped moving postures. The also equipped mecanum wheels,...
Convective heat transfer enhancement can significantly improve the thermal efficiency in conversion, utilization, recovery and storage of energy (in particular solar thermal). Modifying velocity field is most direct approach to enhance convective transfer. However, cases optimal unknown difficult find even for an experienced researcher. In this paper, a predictive optimization methodology based on minimum entropy generation (MEG) principle was developed. A set Euler’s equations were derived...
The commonly used methods in dual-porosity systems assume constant reservoir permeability over an entire range of formation pressure and hydraulic fracture conductivity inside the fractures.
