At Oak Ridge National Laboratory (ORNL), the COMSOL Multiphysics software has become a reliable and important resource to estimate and assess thermal safety margins for several nuclear applications. This poster presentation will highlight some of the ongoing activities in the following ... 詳細を見る
叶片复合材料层的击穿是风电机组遭受雷击后的主要故障形式。对于低电导率的GFRP类叶片铺层而言，雷电先导作用下的强背景电场造成的电击穿可能先于回击电弧的热效应产生。为了获得GFRP铺层的电击穿机理，基于COSMOL Multiphysics软件，建立了引下线-GFRP铺层的流注放电数值仿真模型。考虑了空气域与介质层内部的粒子输运，以及气-固分界面上的电荷沉积与注入作用。通过“稀物质传递物理场” 模块、“静电物理场”模块、“边界常微分和微分代数” 模块以及“稳定对流-扩散方程接口” 模块对控制方程进行求解。依据电场梯度分布进行了网格加密与时间步设置 ... 詳細を見る
Design of the Pressurized Water Reactors (PWRs) involves extensive calculations to verify the reactor safety criteria such as power peaking factor during the reactor lifetime. Coupling of neutronic calculations, thermal hydraulic calculations and other reactor phenomena requires a ... 詳細を見る
A power supply is generally used in many electrical devices. In order to deliver uniform power irrespective of time variation, most plasma equipment also uses a power source. Therefore, the power condition in plasma simulations is essential. In time-dependent models using a current ... 詳細を見る
Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... 詳細を見る
Electrochemical reduction of CO2 to value added chemicals is a promising strategy to mitigate its emission from atmosphere and close the carbon cycle. Although the knowledge on designing electrocatalysts for CO2 electroreduction exists, challenges are associated with developing CO2 ... 詳細を見る
Microreactors have gained popularity in fuel production industry. This is due to its high surface area to volume ratio, enhanced mass and heat transfer, short residence time and a more sustainable practice. The catalytic hydrodeoxygenation (HDO) reaction of 4-Propylguaiacol (4PG) to 4 ... 詳細を見る
Stirred tank bioreactors are used to simulate a natural biochemical environment for the optimum growth of cells (i.e. algae, microorganisms or tissues) in microbial and cell culture. Bioreactor types range from small (5 L and less) up to 15000 L systems for large-scale industrial ... 詳細を見る
The IR CO2 laser powered chemical conversions in the gas phase are intriguing and the researchers’ attention was focused on this transformation a while ago. The method, known as Infrared Laser Powered Homogeneous Pyrolysis, or IR LPHP opened reaction pathways not reached by conventional ... 詳細を見る
RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For ... 詳細を見る
