Summary

In recent years, due to high demands for fuels and their consequential environmental crises, renewable materials have received significant attention. The conversion of biomass to bioenergy includes many steps and mechanisms that are not well studied and understood. However, by advances in computational tools such as molecular dynamics simulations and modeling, these mechanisms are becoming more understandable. Renewable materials are made of various biomolecules that play an important role in their conversion to energy. Considering biochemical conversion methods, there are various enzymes that participate in breaking down biomass into its monomer in bioenergy production, and currently, a huge gap in understanding these processes exists. Computational tools can assist not only in understanding these mechanisms it can be applied in designing novel enzymes with higher capability for the conversion of renewable materials. Moreover, in other processes such as pyrolysis and hydrothermal liquefaction, the intermediate molecules and conversion mechanism are not well known. Understanding the mechanisms and enhanced knowledge about these mechanisms would enlighten our understanding of achieving more sustainable conversion platforms and discover new high-value products.

 

This Special Issue, Computational tools for renewable materials, seeks high-quality works and topics on a better understanding of biomolecules involved in converting renewable materials.

    Abstract In this paper, the occurrence and development mechanism of strain on the cross-section during the wood drying is explored. Therefore, strain regularity on the cross-section of 50 mm thickness elm (Ulmus rubra) board at the temperature of 40°C and 80°C is detected via digital image correlation technology. Hence, the difference between tangential and radial strain at surface and core layers was denoted. The results showed that strain distribution in the width direction of the board is uneven. Moreover, a large drying shrinkage strain occurs at the near-core layer, while the maximum strain difference reaches 4.08%. Hence, the surface of the… More >

    Abstract Municipal sludge is a sedimentation waste produced during the wastewater process in sewage treatment plants. Among recent studies, pilot and field tests showed that chemical conditioning combined with vacuum preloading can effectively treat municipal sludge. To further understand the drainage and consolidation characteristics of the conditioning sludge during vacuum preloading, a large deformation nonlinear numerical simulation model based on the equal strain condition was developed to simulate and analyze the pilot and field tests, whereas the simulation results were not satisfactory. The results of the numerical analysis of the pilot test showed that the predicted consolidation degree was greater than… More >

    Abstract A calculation model of stress field in laser additive manufacturing of walnut shell composite powder (walnut shell/Co-PES powder) was established. The DFLUX subroutine was used to implement the moveable application of a double ellipsoid heat source by considering the mechanical properties varying with temperature. The stress field was simulated by the sequential coupling method, and the experimental results were in good accordance with the simulation results. In addition, the distribution and variation of stress and strain field were obtained in the process of laser additive manufacturing of walnut shell composite powder. The displacement of laser additive manufacturing walnut shell composite… More >

    Abstract Space solar power station is a novel renewable energy equipment in space to provide the earth with abundant and continuous power. The Orb-shaped Membrane Energy Gathering Array, one of the alternative construction schemes in China, is promising for collecting space sunlight with a large-scale spherical concentrator. Both the structural and optical performances such as root mean square deformation, natural frequency, system mass, and sunlight blocking rate have significant influences on the system property of the concentrator. Considering the comprehensive performance of structure and optic, this paper proposes a novel mesh grid based on normal polyhedron projection and spherical arc bisection… More >

    Abstract A new type of microstructure inspired by the cross section of barchan dunes was proposed to reduce windage, which was considered as a passive drag reduction technology in aerospace manufacturing field. Computational fluid dynamics method was carried out to discuss the effect of the microstructure on the skin friction reduction under high velocity flow condition. Different microstructure heights were employed to survey the reduction of drag. The results illustrated that the appearance of microstructure led to a generation of pressure drag in non-smooth model (with microstructures inspired by cross section of barchan dune) in contrast to smooth model. However, the… More >
