[3]Posiva, Eurajoki, Finland

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the ... Read More

Wall Effect on A Spherical Particle Settling along The Axis of Cylindrical Tubes Filled with Carreau Model Fluids

D. Song[1], R. Gupta[1], and R. Chhabra[2]
[1]Dept. of Chemical Engineering, West Virginia University, Morgantown, WV
[2]Indian Institute of Technology, Kanpur, India

The effect of finite boundaries on the drag experienced by a rigid sphere settling along the axis of cylindrical tubes filled with Carreau model fluids has been examined systematically over a wide range of condition. As expected, the presence of finite boundaries leads to an increase in ... Read More

[1]Chemical Engineering Department, University of L’Aquila, L’Aquila, Italy
[2]Faculty of Engineering, University of L'Aquila, L’Aquila, Italy

The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar ... Read More

3D FEM-analysis of a Micromachined Wind Sensor Based on a Self-heated Thermistor Array

A. Talic[1], S. Cerimovic[2], M. Mutapcic[2], R. Beigelbeck[1], and F. Keplinger[2]
[1]Institute for Integrated Sensor Systems, Austrian Academy of Sciences, Wiener Neustadt, Austria
[2]Institute of Sensor and Actuator Systems, Vienna University of Technology, Vienna, Austria

We present COMSOL-based analyses and design optimizations of a micromachined wind sensor. The sensor relies on eight germanium thermistors embedded in a thin silicon nitride membrane, where two orthogonally arranged ensembles, each consisting of four thermistors, are connected to form a ...
