[2]Department of Industrial Engineering, University of Firenze, Firenze, Italy

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can heavily modify the design microclimate and air quality levels. Medical staff presence and movements and sliding ...

Solving Two-scale Transport Laws During Frying of Foods Using COMSOL Multiphysics

J. Maneerote, and P.S. Takhar
International Center for Food Industry Excellence Texas Tech University, Lubbock, TX, USA

Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based fluid transport equations for various phases; near-equilibrium equation governing phase change from liquid ...

Expanding Your Materials Horizons

[2]Department of Biological Systems Engineering, University of Nebraska, Lincoln, NE, USA

Geometries with heterogeneous material properties are typically defined as a set of multiple parts, each part representing a different material. However, assembling or defining the individual parts of complex geometries can be difficult. A practical method based on image-based mesh generation, a custom algorithm for labeling materials, and interpolation functions of COMSOL Multiphysics® can be ...

Implementation of a Viscoelastic Material Model to Simulate Relaxation in Glass Transition - new

Z. Zheng[1], R. Zhang[1]
[1]Corning Incorporated, Corning, NY, USA

Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when ...
