A site-binding/dissociation model is used to determine surface charge in numerical studies of the equilibrium potential and ion distributions inside infinite and finite-length nano-channels. This COMSOL model allows us to investigate the response of surface (zeta) potential to ... Mehr lesen
Cereal foods can be considered as cellular solids: texture is defined by their structure and mechanical properties [1]. Elderly people show a significant alteration of oral health [2] and salivation [3], causing difficulties to eat. Therefore, there is a need to understand chewing ... Mehr lesen
随着城市化的发展，城市下垫面的改造引起城市微气候的改变,比如温度、风速等，这些参数主要受建筑结构、材料、排列方式的影响,在夏季，城市地区温度比周围乡村地区温度高，这种现象也称为城市热岛效应，在全球范围内，这种热岛强度（城乡空气温度差）范围从0.6℃到12℃不等。城市热岛影响人的舒适性和健康，也会加大城市的能源消耗，因此，减少城市多余热量是城市规划者需要考虑的重要因素。此模型采用解决空气与建筑表面和地面热对流传输的CFD模型和解决建筑表面和地面与天空之间短波和长波辐射交换的RAD模型，CFD模型采用雷诺平均纳维-斯托克斯（RANS）方程，考虑热效应的影响 ... Mehr lesen
We use COMSOL Multiphysics® for solving distributed optimal control of un- steady Burgers equation without constraints and with pointwise control constraints. Using the first order optimality conditions, we apply projection and semi-smooth Newton methods for solving the optimality ... Mehr lesen
Growing consumer demand for nutraceuticals has stimulated interest by food companies to increase levels of these health-promoting compounds. Thermal processing of canned foods in a retort produces a unique problem: some of the nutraceuticals are highly sensitive to temperature, and ... Mehr lesen
Background: Even though the direct nose-to-brain drug delivery has multiple advantages, its application is limited by the low delivery efficiency (<1%) to the olfactory region with standard nasal devices. Novel delivery techniques are needed that can deliver clinically relevant dosage ... Mehr lesen
能量存储技术是减少能量浪费和节约能源的最为有效的手段之一。热化学储能技术具备高功率、大容量和低损耗的特点，在实际应用中可近乎无损耗地进行跨季节性利用，上述优点使得热化学储能近年来吸引了国内外学者的广泛关注。热化学能存储过程涉及流动、传热、传质、反应多个物理过程，为了完成实验室级测试到工业级应用的推广，储能设备的仿真模拟是必不可少的一环。为了简化计算，目前几乎所有的数值研究都假设储能材料的孔隙率为均匀且定常的；但在实际的物理过程中，孔隙率与反应程度紧密相关并随时间和空间变化。本文通过推导建立孔隙率变化的热化学储能模型 ... Mehr lesen
Structural safety assessment of cultural heritage masonry structures plays an important role in safeguarding their integrity and conservation. In this regard, masonry modeling is one of the most challenging tasks, since an accurate reproduction of its mechanical behavior is necessary to ... Mehr lesen
We present a modeling software package developed at Ostendo Technologies for analysis and design of semiconductor laser and light-emitting diodes. The current database of material parameters supports complete group of III-Nitride alloys used in visible spectrum applications and can be ... Mehr lesen
Ventilation is mainly used to control indoor air quality and for the purpose of thermal comfort by diluting and displacing pollutants. Because of the effects it has on health, comfort, and serviceability, indoor air quality in our homes is becoming of increasing concern to many people. ... Mehr lesen
