This book was released on 2012 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase transport in unsaturated swelling porous materials involves fluid mass transport, heat transfer as well as swelling of the porous solid matrix. Neglecting the deformation of the solid matrix can lead to erroneous results when modeling transport phenomena in porous materials. In particular, many porous materials exhibit viscoelastic effect upon wetting/drying, which can expedite or slow the transport process. This work presents modeling and simulation of two-way coupling of multiphase transport and viscoelastic large deformation of unsaturated swelling porous systems based on fundamental physics. The work includes the development of a thermomechanical theory for multiphase transport in unsaturated swelling porous media based on the Hybrid Mixture Theory (saturated systems can also be modeled as a special case of this general theory). The theory includes three phases: solid matrix, fluid and air and uses the Coleman-Noll procedure to obtain restrictions on the form of the constitutive equations. Derived relationships include, for example, a modified Darcy's law, which takes into account both Fickian and non-Fickian transport, and a viscoelastic constitutive relationship that relates the stress and strain tensors for the solid phase. A model is then developed based on this theory for isothermal conditions which involves a simple form of a differential-integral equation that governs the fluid transport and is fully coupled with the solid large deformation. Numerical implementation of this model is then presented that involves a finite element analysis of water absorption of plane sheet pasta and numerical results of sorption curves show good agreement with experimental results obtained from the literature. Importance of including viscoelastic relaxation is investigated for soaking processes of pasta. Drying of potato is also considered in this work as an important example of two-way coupling of multiphase transport and viscoelastic large deformation of the solid matrix of porous materials because during drying processes, the transition of outer surface of the material from rubbery to glassy state at low moisture content can slow or stop shrinkage of the materials, and thus viscoelasticity plays an important role.

Download or read book Heat and Mass Transfer Modelling During Drying written by Mohammad U.H. Joardder and published by CRC Press. This book was released on 2021-09-30 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most conventional dryers use random heating to dry diverse materials without considering their thermal sensitivity and energy requirements for drying. Eventually, excess energy consumption is necessary to attain a low-quality dried product. Proper heat and mass transfer modelling prior to designing a drying system for selected food materials can overcome these problems. Heat and Mass Transfer Modelling During Drying: Empirical to Multiscale Approaches extensively discusses the issue of predicting energy consumption in terms of heat and mass transfer simulation. A comprehensive mathematical model can help provide proper insight into the underlying transport phenomena within the materials during drying. However, drying of porous materials such as food is one of the most complex problems in the engineering field that is also multiscale in nature. From the modelling perspective, heat and mass transfer phenomena can be predicted using empirical to multiscale modelling. However, multiscale simulation methods can provide a comprehensive understanding of the physics of drying food materials. KEY FEATURES Includes a detailed discussion on material properties that are relevant for drying phenomena Presents an in-depth discussion on the underlying physics of drying using conceptual visual content Provides appropriate formulation of mathematical modelling from empirical to multiscale approaches Offers numerical solution approaches to mathematical models Presents possible challenges of different modelling strategies and potential solutions The objective of this book is to discuss the implementation of different modelling techniques ranging from empirical to multiscale in order to understand heat and mass transfer phenomena that take place during drying of porous materials including foods, pharmaceutical products, paper, leather materials, and more.

Download or read book Mathematical Modeling of Inelastic Deformation written by J.F. Besseling and published by CRC Press. This book was released on 1994-05-15 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Modeling of Inelastic Deformation details the mathematical modeling of the inelastic behavior of engineering materials. The authors use a thermodynamic approach to the subject and focus on crystalline materials, but not to the exclusion of macro-moleular solids. Within a unified theory for small and large deformations, they develop simple models, such as the elastic-perfectly plastic model, as well as complex models dealing with anisotropic hardening. The book includes finite element implementation of the theory and illustrates the implementation with examples from heat production and conduction processes.
