Vertical axis wind turbines (VAWTs) are easier to install and maintain since the rotor shaft they attached to is typically set transverse to the wind direction. Therefore, the generator and rotation transmission mechanisms can be placed at the base level, where it is close to the ground. ... Read More
Flow of lava in underground lava tubes is an important mechanism in volcanic eruptions. Most direct measurements of active lava tube flows are typically impossible due to unstable and dangerous terrain, high temperatures (2140°F / 1170°C), and complex and spatially extended tube networks ...

Introduction Oversized microbubbles traveling through confining conduits can create flow blockages when the lubrication layer surrounding them drains, requiring undesirable increases in pressure gradient for discharging channel contents. In increasingly demanding industrial ... Read More
A classic problem in process engineering is the estimation of the excess friction loss that occurs as a fluid passes through a sudden expansion. At elevated Reynolds numbers (Re) there are simple correlations that provide reasonable estimates of the pressure drop across an expansion. ... Read More
Meshless methods are relative newcomers to the field of computational methods; the term “meshless method” refers to the class of numerical techniques that have the following advantages: (1) domain and boundary mesh discretization is not required; (2) domain integration is not required; ...

Background: Sensorineural hearing loss is the most common type of hearing impairment. One novel method to treat this form of hearing loss is by regenerating the synaptic connections between the extant Spiral Ganglion Neurons (SGNs) and transplanted human stem cell derived SGNs. Brain ... Read More

储氢合金的PCT曲线和氢化动力学性能是描述合金储氢性能的重要标准，目前对合金的PCT曲线测试一般采用体积法，对合金氢化反应动力学的研究一般采用等容差压法。但在实际生产过程中，储氢合金通常是在恒定氢气流速的情况下工作的，所以研究合金在恒定氢气流速条件下的吸氢动力学性能很有必要。与实验相比，采用数值模拟预报合金的吸放氢性能节省了大量的时间和成本，具有突出优势。目前金属Pd及其合金被广泛应用于储氢及氢气纯化等领域，我们通过COMSOL软件建模，构建Pd吸氢热力学与动力学特性模型，选用传热、流体流动、域常微分等物理场模块建立了Pd在恒定氢气流速下吸氢动力学的计算模型 ... Read More
钙钛矿纳米晶的合成通常是使用间歇式搅拌系统进行（将前驱液滴加入反溶剂甲苯）。宏观间歇式反应器在高耗能的同时，并不能保证制备的纳米晶的尺寸均匀可控，实验的重复性也不好。而微流体具有高效的传质传热特性，以及良好的可操纵性。同时体系反应体积的急剧下降使得反应过程的不确定性大大降低。这样保证所有晶体拥有相同的成核和生长环境。所以使用微反应器制备的纳米晶的尺寸均匀可控。由结晶动力学可知，结晶过程的溶液过饱和度以及晶核周围的速度场分布对产物晶体有影响。所以我们使用COMSOL软件对比了微反应器和间歇式反应器运行时的体系的速度场和浓度场的分布情况。以达到调控产物晶体的质量的目的。 Read More
