AIChE Journal, EarlyView.Abstract Bayesian estimation enables uncertainty quantification, but analytical implementation is often intractable. As an approximate approach, the Markov Chain Monte Carlo (MCMC) method is widely used, though it entails a high computational cost due to frequent evaluations of the likelihood function.

A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip
Advanced Intelligent Discovery, EarlyView.A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.

Modelling of natural convection along isothermal plates and in channels using diffusion velocity method [PDF]
Maejo International Journal of Science and Technology, 2010 The diffusion velocity method (DVM), a version of vortex element method (VEM), was used to model the steady state, laminar natural convection flows along isothermal vertical plates and in isothermal vertical channels. For each case, numerical models were

Evolution of Physical Intelligence Across Scales
Advanced Intelligent Discovery, EarlyView.By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Hybridized discontinuous Galerkin method for convection–diffusion problems [PDF]
Japan Journal of Industrial and Applied Mathematics, 2014 In this paper, we propose a new hybridized discontinuous Galerkin (DG) method for the convection-diffusion problems with mixed boundary conditions. A feature of the proposed method, is that it can greatly reduce the number of globally-coupled degrees of freedom, compared with the classical DG methods.

Exergy and Economic Analysis of Hybrid Mechanical Vapor Compression and Membrane Distillation
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Hybridization of two or more desalination processes has been identified as an attractive option for improved energy efficiency and recovery rate. To appropriately assess the performance enhancement of hybrid desalination systems, an integrated approach for energy, exergy, economic, and environmental investigations should be adopted. This study

A gradient-enhanced approach for stable finite element approximations of reaction-convection-diffusion problems [PDF]
Journal of Theoretical, Computational and Applied MechanicsWe develop a micromorphic-based approach for finite element stabilization of reaction-convection-diffusion equations, by gradient enhancement of the field of interest via introducing an auxiliary variable. The well-posedness of the coupled-field approach

Photothermal Interfacial Evaporation Characteristics of PVA/SA–CNT–Borax Hydrogel
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The desalination of seawater has demonstrated significant potential to use solar‐driven interfacial evaporation technologies due to its sustainability, outstanding productivity, and kindness to the environment. In this paper, a hydrogel interfacial evaporator was produced, with PVA and SA as the base materials. The addition of carbon nanotubes

A Novel Characteristic Expanded Mixed Method for Reaction-Convection-Diffusion Problems
Journal of Applied Mathematics, 2013 A novel characteristic expanded mixed finite element method is proposed and analyzed for reaction-convection-diffusion problems. The diffusion term ∇·(a(x,t)∇u) is discretized by the novel expanded mixed method, whose gradient belongs to the square ...
