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, cerebral blood flow (CBF) is modeled using a mathematical model, a statistical model and numerical examples. In the mathematical model, blood flow is described using Navier-Stokes equations. In the statistical model, the experiments or the data measurement process is simulated and to study how the noise in the measurements affects the ability to estimate the parameters, ...

A commercial heat probe is used for energy transfer measurements on copper and silicon substrates. To do so, the micro sensor has to be calibrated under high vacuum (~10-7 mbar), using a homemade black body as a heat source.Although the HFM is cooled at 5 oC, the solid surface temperature is unknown as the thermal contact resistance. Thus, COMSOL simulations are also used to obtain reliable ...
Simulation-based Analysis of the Spatial Sensitivity Function of an Electrical Capacitance Tomography System

Institute of Electrical Measurement and Measurement Signal Processing, Graz University of Technology, Graz, Austria
This paper investigates the effects of the soft field character of an Electrical Capacitance Tomography system by means of analyzing the 3D sensitivity distribution of the pipe interior using Finite Element Analysis.The aim of the determined sensitivity is to overcome restrictions caused by the soft field without being forced to use (active) guarding strategies.

COMSOL Multiphysics was used to model and simulate the thermal performance of solid targets irradiated with charged particles.Results showed that materials with a high thermal conductivity to heat capacity ratio behave better in cooling dynamic systems requiring fast dissipation of heat.
Effects of Plasma Rotation and Magnetic Fields on Convection Flows in the Horizontal Burning High Intensity Discharge Lamps
OSRAM SYLVANIA, Beverly, MA, USA
In this presentation, the effect of a uniform applied magnetic field and a non-uniform field due to a line current (from the lead wire that powered the lamp) are studied and the magnetic fields required to center the arc plasmas are determined. The effects of plasma rotation induced by arc-tube rotation on plasma flows and temperatures are also studied. Critical slip velocities to change the flow ...

Eddy Current Non Destructive Testing is exploited to evaluate the structural integrity of metallic objects. The aim of this paper is to detect defects located in depth within the inspected object; within this framework, we studied the modelling of exciting coils useful to detect structural flaws. The simulations have been carried out by considering the movement of the coil over a structural steel ...

Small nuclear ribonucleoprotein particles (snRNPs) are essential supramolecular complexes involved in pre-mRNA splicing, the process of post-transcriptional RNA modifications. The particles undergo complex assembly steps inside the cell nucleus in a highly dynamic compartment called the Cajal body. We have previously shown that the free diffusion model does not fully describe the snRNP motion ...

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic fields easily with studied objects. They can concentrate on physical effects instead on reading figures. Here, an ...
Development of an Interlinked Curriculum Component Module for Microchemical Process Systems Components Using COMSOL Multiphysics

COMSOL Multiphysics provides a powerful numerical platform where various models for microchemical process technology components can be readily created for both education and research. This modeling tool allows chemical engineering students to focus on understanding the effects of various microchemical system component design and operational parameters versus coding and debugging of the numerical ...
