Silver and gold nanoparticles are widely used in the field of surface enhanced raman spectroscopy (SERS) because of the unique plasmonic properties. Plasmons or surface plasmon resonance result from the wavelength dependent dielectric properties of noble metals like Ag, Au, Pt etc., ... Mehr lesen
Harvesting of renewable energy requires efficient energy storage systems. Rechargeable flow batteries offer certain advantages over other energy storage techniques in use, such as the lifting of water, compression of air, flywheel, etc. In a flow battery, electrolyte flowing through ... Mehr lesen
This paper presents a methodology towards designing, analyzing and optimizing piezoelectric interdigitated microactuators using COMSOL Multiphysics. The models used in this study were based on a circularly interdigitated design that takes advantage of primarily the d{;sub}33 ... Mehr lesen
Gas-liquid falling film microreactors carry out fast exothermic and mass transfer limited reactions. Since the major rate limiting steps occur on the liquid side, it is important to account for a realistic liquid film profile within the reactor simulation. Based on realistic channel ... Mehr lesen
Some types of mechanical devices, such as molds, but not only, include a large number of micro-mechanisms, valves, channels, vents, or other devices subject to deterioration or malfunctioning, frequently caused by unwelcome phenomena such as incrustations, fillings, or reciprocal bonding ...

引言:激光诱导间质肿瘤热疗法是一种可使生物组织局部地方凝结坏死的肿瘤疾病治疗方法,目前已经用于肝、脑等各部位的肿瘤治疗[1-2]。为了更好地进行肿瘤疾病的治疗,需要实时地对组织的温度和热损伤进行监控,而检测技术很难实现对肿瘤治疗过程的实时监测,故数值计算成为研究光热疗法的有力工具[2-6]。本模型将生物组织光传输的物理场与热传输的物理场相耦合,考虑组织光热参数随温度变化的情况,研究了肿瘤周围含有大动脉的情况时组织的温度分布随时间的变化情况,研究结果对指导临床医学肿瘤治疗有重要意义。 COMSOL Multiphysics® 的软件使用: 几何模型:如图1所示 ... Mehr lesen
Thermal ablation is a treatment option in oncology that can be used to target primary and metastatic cancers. In this approach, high temperature heating is administered at the target tumor site to induce coagulative necrosis of malignant cells. One minimally invasive method for ... Mehr lesen
Investment casting is practised in both the automotive and aerospace industries, to produce casted components where a high-quality surface finish is critical. Vacuum induction melting (VIM) and direct pouring into an investment casting shell mould is an advantageous manufacturing ... Mehr lesen
基于 Level-Set 界面跟踪方法建立了激光熔覆过程的三维瞬态数值模型,研究了瞬态熔化和凝固过程中传热传质的演化规律。该模型使用 Level-Set 方法跟踪熔池气/液界面,采用焓-多孔度(enthalpy-porosity)方法得到了固/液界面之间的糊状区,并考虑了质量添加、材料熔化/凝固、热毛细效应(Marangoni效应)、浮力效应、活性元素质量传输等对熔池流动和界面的影响。通过该模型,具体分析了质量添加、力和界面平衡条件对熔池气/液界面的影响,以及由熔池温度/浓度分布引起的热毛细效应、金属材料的熔/凝过程和熔池流动形式对熔池固/液界面的影响。结果表明 ... Mehr lesen
