Summary

Manufacturing is not only the foundation of national economic growth and productivity, but also an important support for building development strategic advantages. Interpreting, describing, predicting and simulating changes in various behaviors and characteristics during manufacturing and material processing is the key to optimizing product attributes. With the development of Industry 4.0 and smart technology, intelligent manufacturing has gradually become an effective means of efficient production. However, even on the basis of smart technology, many physical phenomena will occur in the manufacturing process, such as heat transfer, fluid dynamics, solid mechanics, changes in material state and performance, internal stress, phase transitions, and structural changes, etc. This makes the computational and numerical simulation of manufacturing and material processing very challenging.

Therefore, this special issue aims to publish new and novel original research related to intelligent manufacturing and all classes of material processing. The focus is on the research of computational mechanics, numerical simulation, modeling and fluid dynamics in the manufacturing and material processing processes.

The topics of interest include but are not limited to:

• Finite element and finite-element-based methods

• Numerical methods of structural mechanics analysis

• Molecular dynamics simulations

• Molecular mechanics modelling

• Advanced numerical technology of manufacturing and materials

• Material processing and dynamics in intelligent manufacturing

• Fluid transport simulation and modelling

• Multi-physics problems

• Inorganic and organic fluids

• Interaction mechanisms during material processing

• Engineering design, optimization and manufacture

    Abstract In order to ensure the safe operation of the compressors used in water chillers, in the present study some interlock protections have been added to the related design. These include a low pressure protection, a high pressure protection, an exhaust temperature protection and a differential pressure protection. Some tests have been conducted by tuning the saturation suction and exhaust temperatures of the compressor through adjustment of the cold source outlet temperature and the ambient temperature. The results show that the ambient temperature increases with decreasing device load and increasing fan speed under the same saturated suction temperature; the device refrigerating… More >

    Theoretical and Experimental Analysis of Heat Transfer and Condensation in Micro-Ribbed Tubes

    Daoming Shen, Jinhong Xia, Chao Gui, Songtao Xue

    (This article belongs to this Special Issue: Computational Mechanics and Fluid Dynamics in Intelligent Manufacturing and Material Processing)
    Abstract The thermal transmission coefficient for a micro-ribbed tube has been determined using theoretical relationships and the outcomes of such calculations have been compared with experiments conducted using a R1234yf refrigerant undergoing condensation. In particular four theoretical single-phase flow and three multi-phase flow models have been used in this regard. The experimental results show that: the Oliver et al. criterion equation overestimates the experimental results as its accuracy is significantly affected by the specific conditions realized inside micro-fin tubes; the Miyara et al. criterion equation prediction error is less than 15%; the Cavallini et al. approach gives the highest prediction accuracy;… More >

    Abstract Gases containing sulfur oxides can cause corrosion and failure of bellows used as furnace blowers in high-temperature environments. In order to mitigate this issue, the behavior of an effective blast furnace blower has been examined in detail. Firstly, the Sereda corrosion model has been introduced to simulate the corrosion rate of the related bellows taking into account the effects of temperature and SO2 gas; such results have been compared with effective measurements; then, the average gas velocity in the pipeline and the von Mises stress distribution of the inner draft tube have been analyzed using a Fluid-Structure Interaction model. Finally,… More >

    (This article belongs to this Special Issue: Computational Mechanics and Fluid Dynamics in Intelligent Manufacturing and Material Processing)
    Abstract To improve the application of discrete element models (DEM) to the design of agricultural crushers, in this study a new highly accurate model is elaborated. The model takes into account the fiber structure, porous nature of the material and the leaf sheath coating structure. Dedicated experimental tests are conducted to determine the required “intrinsic” and basic contact parameters of the considered banana straw materials. A large number of bonding parameters are examined in relation to the particle aggregation model in order to characterize different actual banana straws. Using the particle surface energy contact model, the viscosity characteristics of the crushed… More >
