Biopreservation deals with the protection and storage of complex biologics such as proteins, lipids, and recently, mammalian cells. One preservation method, known as lyopreservation, involves placing a biologic inside a water droplet with some type of sugar excipient (sucrose, trehalose, ... 詳細を見る
碱性锌铁液流电池是一种新兴的电化学储能技术，其具有价格低廉、环境友好、能量密度高等特点，具有巨大的发展潜力。但目前尚缺乏相关的理论研究，制约了其性能的提高。这项工作运用COMSOL建立了一个瞬态二维的碱性锌铁液流电池充放电模型。模型耦合了电化学模块中的三次电流分布接口与全局常微分和微分代数方程接口，用于刻画电池的电化学反应过程与电池及外部电解槽的质量平衡。该模型参考了案例库中的钒氧化还原液流电池、可溶性铅酸氧化还原液流电池和锌-氧化银电池一维等温模型三个案例，考虑了电化学反应所导致的电极中的孔隙率和物质浓度的变化 ... 詳細を見る
Simulated Thermal Response Test (TRT) data are analyzed in order to evaluate the effect of the tridimensionality model’s feature in determining the proper value of the soil thermal conductivity and borehole thermal resistance. The 3D system’s simulation during the TRT is ... 詳細を見る
COMSOL Multiphysics can be used to model a latent heat energy storage system. A 2D numerical study was performed to simulate melting of a PCM including both conduction and convective heat transfer. The heat transfer in fluids and laminar flow physics interfaces were used. To model ... 詳細を見る
The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). ... 詳細を見る
This paper reports the design of a piezoelectric energy harvesting micro generator for an energy autonomous tire pressure monitoring wireless sensor node. For our design we use a piezoelectric MEMS generator approach without additional mass. The intrinsic mass of the cantilever is in the ... 詳細を見る
The understanding of the tracer migration in two-phase porous media systems and its reaction over the fluid-fluid interfaces is a challenging task important for a number of engineering applications, e.g. oil recovery, carbon capture and storage in geological reservoirs, remediation ... 詳細を見る
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 ... 詳細を見る
An alternative approach to integration of a local heat source with the digital microfluidic (DMF) platform by attaching inkjet-printed silver microheaters to the bottom plate was recently introduced (Sathyanarayanan et al., MNE 2017). This approach allows more degrees of freedom to the ... 詳細を見る
In many groundwater studies, the areal extent of an aquifer is much larger than its thickness so that flow and transport take place primarily in horizontal directions. Thus, the most common type of modeling in practical applications is two-dimensional involving vertically averaged ... 詳細を見る
