Materials with an order variable in thermal conductivity as a function of temperature are desirable for thermoelectric heat energy recovery, building thermal insulation and solar thermal applications. Thermal Conductivity is an inherent material property. Engineering the fundamental ... 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
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
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
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
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
A Dutch firm manufactures a mounting system to fasten roof workmen to the roof of a flat roof building to prevent them from falling down from the roof. The system is mounted to the flat roof afterwards, i.e. after the completion of the thermal insulated roof. Because of the mechanical ... 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
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
Modeling the acoustic output of wind turbines presents extreme simulation challenge due to the geometry of rotors and towers requiring very large mesh size with large volumes of empty space between blades. In this paper, the structural-acoustic finite element models that were previously ... Mehr lesen
