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 ... 詳細を見る

Phonons underlie the propagation of sound and the transport of heat in materials. With outstanding progress in the design of phononic crystals, it is now feasible to control the acoustic properties of these materials and to endow them with unique acoustic properties. For instance, it ... 詳細を見る

Photo-bioreactors generate biomass by providing a controlled environment for the cultivation of algae due to photosynthesis. Algae cultivation can be controlled through the operating parameters and bioreactor environment to allow for high productivity and the use of systems with large ... 詳細を見る

The antenna pattern synthesis problem is of the utmost importance in almost every kind of antenna applications. Therefore, a very large number of contributions have appeared on this subject. A number of different implementation methods are well known, and widely used. In this paper we ... 詳細を見る

Three dimensional mathematical models are developed to simulate the blood flows in patient specific right coronary arteries with two stenoses. Simulations are carried out with various flow parameters under physiological conditions. Both Newtonian and non-Newtonian blood viscosity models ... 詳細を見る

Transdermal drug delivery (TDD) is used to deliver drugs through the skin as an alternative to oral, intravascular, and subcutaneous routes. While there are many advantages to TDD, skin is a very effective barrier and provides resistance to drug delivery. To improve drug delivery ... 詳細を見る

Pore-level displacement of heavy-oil during thermal operations such as SAGD and CSS is a complex multi-scale phenomenon. As gravity drainage is the main depletion mechanism within the intergranular pore space, the surface tension-related phenomena are dominant in intra-granular micro ... 詳細を見る

Present study discusses a new method of how to apply numerical simulation in COMSOL Multiphysics® software to improve the accuracy of polymer melts viscosity measurements. The main emphasis is placed on evaluating the effects of entrance and exit geometry of a capillary rheometer on ... 詳細を見る

Reynolds Numbers effect: In the first bend, the higher the Reynolds number, the longer the first pair of vorticities stays attached to the wall. In the second bend, the higher Reynolds Numbers, the secondary flow from the first bend dominates. Curvature Radius effect: The smaller the ... 詳細を見る

The advanced gravitational wave detectors require injecting a high continuous power laser into the optical cavities of the interferometers to reach their design sensitivity. To mitigate the thermal aberrations created by absorption of this high power load into the various optical ... 詳細を見る
