A novel combined photovoltaic-thermal panel can simultaneously increase the conversion efficiency of the PV cell and utilize some of the excess thermal energy created by the conversion process (see Figure 1). The Conjugate Heat Transfer physics in COMSOL was used to create a two ... 詳細を見る

The Molten Salt Reactor (MSR), proposed along with other five innovative concepts of fission nuclear reactor by the Generation IV International Forum (GIF-IV), represents a challenging task from the modeling perspective because of the strong coupling between neutronics and thermo ... 詳細を見る

We report here on the use of the COMSOL emw (electromagnetic waves) module in the design of a microwave launcher. This launcher is to be used in a microwave Doppler sensor that is incorporated into a chemical looping combustion system. The launcher is designed in two steps. First, we ... 詳細を見る

Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... 詳細を見る

A kernel of grain is modeled as an isothermal sphere, with descriptive differential equations scaled or rendered into non-dimensional form, where moisture transfer is governed by internal diffusivity, not by surface conditions. The time dependent problem is solved with COMSOL and the ... 詳細を見る

As an effective method to cope with green-house gas emission, and to enhance oil recovery, injection of carbon dioxide into oil reservoirs has obtained increasing attentions. The flooding process involves complex phase behavior among oil, brine and CO2, and geochemical reaction between ... 詳細を見る

Focused ultrasound systems guided by magnetic resonance imaging (MRI) and thermometry have recently made possible the non-invasive thermal ablation of benign tumors such as uterine fibroids in clinical practice. Much more work is however required in order to make this technology ... 詳細を見る

In this paper heat losses and gains are assessed for a specific measuring set-up improving the validity of performance data to accurately predict the initial stage of a boiling curve. Simulation focus on achieving results predicting real measuring data of a plain surface structure. ... 詳細を見る

NASA and the Department of Defense have interest in the development of satellites which are several orders of magnitude smaller than those currently in use. These ‘nanosats’ will require new propulsion systems to offer precise thrust and impulse-bit characteristics on the order of 10 ... 詳細を見る

Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our ... 詳細を見る
