Adequate cooling of beverages is a major issue in planning of several types of events, e.g. poster sessions at conferences. One crucial factor is the time needed to cool beverages from its initial temperature to the desired drinking temperature. We present a way to determine a close approximation for the cooling behavior of three types of commonly used beverage containers using COMSOL ...

We develop a porosity-optimization problem to improve the electrochemical reactions taking place in hydrogen fuel cells. We introduce a mathematical model, which involves a system of conservation laws defined in a porous space domain. Our goal is to find the domain's optimal porosity function that can make the oxygen-hydrogen reaction as uniform as possible. The optimal porosity design ...

The delivery of chemotherapy for cancer into the central nervous system, in particular the brain, remains a challenge. This results in brain metastases commonly being a cause of death from cancer. Here, we look at the environment of the blood-brain barrier. Then, we explore two proteins (breast cancer resistance protein and p-glycoprotein) that may inhibit the transport of medications (erlotinib ...

Several acoustic vector-sensor (AVS) configurations have been tested for direction of arrival (DoA) estimation in a diffused reverberant environment using pressure gradient method. The discrete pressure sensors have been arranged with different geometrical placement and pressure gradients have been estimated for finding DoA of an acoustic source. The received signals at the pressure sensor for ...

In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. These stresses are expected to influence the integrated performance of the magnet system. In this ...

This paper addresses the modeling of a complex glass forming process as an example of a complex, nonlinear distributed parameter system. The system is modeled by a fluid dynamics approach, which means that the forming is regarded as a fluid with free surfaces. Here, the coupling of the forming process with the heat flow is considered. The influence of crucial model parameters (e.g., dynamic ...
