In this paper, we present a mathematical model of contractile elastic solids meant to simulate various districts of the cardiovascular system, and based on the concepts of active deformation and embedded muscle fibres. Specifically, here we deal with the modeling of the gross mechanics of the Left Ventricle (LV) which is strictly related to its pump function. As is well known, the effectiveness ...

Heat transfer in a plane shear flow configuration consisting of two infinitely long parallel plates is considered. In laminar flows over undulated substrates eddies can be generated due to the kinematical constraints. A closed form analytical solution for the velocity field, based on lubrication theory as well as a semi-analytic solution for the temperature field is derived for the creeping flow. ...

The NovaSure Endometrial Ablation System® is designed to remove the endometrial lining in the uterine cavity of women who suffer from menorrhagia. The NovaSure disposable device consists of a 2-pole, 4 electrode array that is inserted into the uterine cavity and deployed. We have developed a COMSOL Multiphysics model of the NovaSure ablation process. The model utilized COMSOL Multiphysics ...

Two designs for thin layer flow cells were set up at University of Ulm, Germany, in order to identify parameters describing the kinetics of methanol-oxydation – reactions, to be utilized in fuel cells. Computer models for two designs were constructed using COMSOL Multiphysics. Results from the numerical simulations were used to evaluate the different flow cell designs. The aim to ...
Simulation of the Inverse Extrusion of a Brass Rod by the Coupling of Fluid, Mechanical, Thermal and Ale Modules

An efficient simulation of the inverse extrusion process has been performed through the coupling of three modules in COMSOL Multiphysics: fluid-dynamics, general heat transfer and ALE. The strain, the strain rate, and the stress field can be completely defined after the complete definition of the velocity field of the material under the action of the tool. The definition of the stresses and of ...

In this presentation we present our analysis of the PARC Nanocalorimeter. Calorimetry is basically the measuring of heat of chemical reactions or physical changes. Nanocalorimetry is Calorimetry at the Nanometer scale. The PARC Nanocalorimeter is a special type of Calorimeter, it consists of arrays of Nanocalorimeters. The PARC Nanocalorimeter is intended to be used for screening biochemical ...

In this presentation we consider the modeling of indoor air quality, and pollutant transport. Today's aspects of indoor air quality unfortunately must include the potential risk of an attack with biological weapons. In this presentation, we illustrate the effect of such an attack. In the present work, we also present numerical results for indoor air quality for a specific building, namely ...
