What adsorption model can be used for solid liquid adsorption?5 answersThe fractal pseudo-first-order model is a suitable choice for solid-liquid adsorption processes. This model accurately describes the interrelationships between pollutants and adsorbents, dynamic adsorption results, and provides a fractal-like modeling approach for experimental data. It offers a more statistically accurate representation compared to the canonical pseudo-first-order model, with a lower hybrid fractional error function value, indicating better estimation of the degree of surface coverage. The fractal model considers an instantaneous rate coefficient influenced by various factors like particle size, specific surface area, and pore volume, making it a comprehensive choice for understanding adsorption mechanisms in solid-liquid systems.
What is a unified solidification model?5 answersA unified solidification model is a mathematical framework that combines different aspects of solidification processes into a single model. It allows for the modeling of various phenomena such as non-equilibrium solidification/melting, non-isothermal dynamic wetting, and microstructure evolution. This approach eliminates the need for ad hoc assumptions and provides a conceptually consistent way to describe fluid flows with phase transitions and dynamic wetting. The model can explain the arrest of a moving contact line in the impact and spreading of a molten drop on a cold substrate, as well as the formation of interfaces and the behavior of materials during additive manufacturing processes. It can also predict the characteristics of melt pools, phase evolution, and residual stresses in laser powder bed fusion. The unified model aims to sequentially predict solidification microstructure, residual stresses, and structural cracking.
How to model residual stress during solidification in OpenFOAM?5 answersResidual stress during solidification can be modeled in OpenFOAM by developing a finite volume solver to simulate the behavior of pore pressure and shear stress in the soil. Additionally, a criterion based on the accumulated pore pressure can be applied to predict the onset of residual liquefaction. Another approach is to use numerical finite-element models to analyze the effects of temperature gradient and progressive solidification on residual stress. A reduced-order modeling strategy can be employed to efficiently reproduce the final residual stress state in additive manufacturing processes. Computational fluid dynamics analysis and phase-field modeling can be used to predict melt pool characteristics, solidification microstructure, and residual stresses in laser powder bed fusion processes. The numerical simulation of temperature field and stress field during solidification can be carried out using professional casting simulation software, such as ProCAST. A numerical simulation system that integrates finite difference and finite element methods can be established to model the stress evolution, residual stress, and deformation during casting solidification.
How is the pressure behavior on a solidification problem?4 answersThe behavior of pressure on solidification processes has been investigated in several studies. It has been found that applying pressure during solidification can improve the microstructure and mechanical properties of composites. High pressure can also alter the matter state and change physical and chemical properties, leading to the synthesis of new metastable compounds. In the case of metallic materials, high pressure during solidification can affect the solidification microstructure, phase constitution, and mechanical properties. Molecular dynamics simulations have shown that pressure influences nucleation rate, growth modes, and crystallite size during solidification. Additionally, pressure can affect the inclusion number distribution, phase transition sequences, and heat transfer boundary conditions during solidification. Overall, the understanding of pressure behavior on solidification is still an active area of research, and more experimental and theoretical investigations are needed to fully comprehend its effects.
How open cell foams improve the heat transfer in catalytic reactors ?5 answersOpen cell foams improve heat transfer in catalytic reactors due to their large specific surface area, high void fractions, and enhanced internal mass transport. These features make them attractive as catalyst supports in structured reactors for multiphase systems. The use of open cell foams as catalyst supports allows for a high catalyst loading while maintaining significant void fraction. Additionally, open cell foams provide low pressure drop, radial mixing, and exceptional heat transport properties, making them suitable for small-scale, dynamically operated reactors with strongly exothermic reactions. The understanding of structure-heat transport relations is key for designing efficient and safe structured reactors using open cell foams. Conduction is the dominant heat removal mechanism in open cell foams, and the strut diameter and solid thermal conductivity are key parameters for improving heat transport and reducing hot spots. Overall, open cell foams offer improved heat transfer capabilities in catalytic reactors, making them a promising option for process intensification.
How can we use OpenFOAM to model tsunami waves?4 answersOpenFOAM can be used to model tsunami waves by employing three-dimensional multiphase models that consider various important factors such as a sharp water-air interface, granular rheology for landslides, differentiation between effective pressure and pore pressure, and porosity, dilatancy, and permeability. These models simulate complex events with a relatively simple approach, although at a high computational cost. The parameters of the model are intrinsic material parameters, allowing for event prediction without significant parameter optimizations. Another approach involves using a Volume-Averaged Reynolds-Averaged Navier-Stokes solver, IHFOAM, developed in the OpenFOAM environment, to assess the attack of a tsunami on a rubble mound breakwater. Additionally, a three-dimensional non-hydrostatic model has been extended to compute submarine-landslide-generated waves, providing a good agreement with experimental data. The use of unstructured meshes adapted to the distribution of ocean depths can also enhance the numerical efficiency of tsunami models in OpenFOAM.
