为了不断地增加磁存储密度，机械硬盘中磁头和盘片之间的间隙，即飞高，已经减小到了 10nm 以下，以比特磁记录技术（BPM）和热辅助磁记录技术（HAMR）为代表的新兴技术不断涌现，给磁头磁盘界面的超薄气体润滑特性研究提出了新的挑战。 COMSOL Multiphysics® 的使用：由于在超薄气体润滑领域，连续介质模型已经不再适用，控制方程为玻尔兹曼方程。本文以 F-K 模型为控制方程，此模型是在线性玻尔兹曼方程和 BGK 方程基础上结合流量连续条件建立的修正雷诺方程。我们使用了 COMSOL Multiphysics® 中的 PDE 接口进行了自定义修正雷诺方程的建模 ...

Three dimensional mathematical models are developed to simulate the blood flows in patient specific right coronary arteries with two stenoses. Simulations are carried out with various flow parameters under physiological conditions. Both Newtonian and non-Newtonian blood viscosity models ... Mehr lesen
A frequency-domain finite element (FE) technique for computing the acoustic scattering from axially symmetric fluid-loaded structures subject to a nonsymmetric forcing field based on Ref. 1 is extended to poroelastic media and implemented in COMSOL Multiphysics® software. This method ... Mehr lesen
Precise electrochemical machining (PEM) is an innovative machining technology which results from further development of the electrochemical sinking. PEM works with pulsed low frequency direct current and oscillation of the tool electrode. As part of the project ‘Electrochemical machining ... Mehr lesen
Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics® is used to describe an intermediate temperature solid oxide fuel ... Mehr lesen
The maintenance plan or rush-to-repair of a subsea pipeline for oil transport may result in the shutdown of the line, in other words, may stop the flow of fluid. During the shutdown, the temperature of the oil tends to decrease continuously, and the heavy molecules tend to crystallize ... Mehr lesen
Reynolds Numbers effect: In the first bend, the higher the Reynolds number, the longer the first pair of vorticities stays attached to the wall. In the second bend, the higher Reynolds Numbers, the secondary flow from the first bend dominates. Curvature Radius effect: The smaller the ... Mehr lesen
Modern wind turbine blades consist of composite airfoil shaped structures that form a hollow acoustic cavity. Because of continually varying aerodynamic forces, gravitational loads, lightning strikes, and weather conditions, all blades will experience leading and trailing edge splits, ... Mehr lesen
A rotational rheometer for Self-Consolidating Concrete was simulated as a yield-stress fluid in a 2D geometry. The effect of the vane geometry was investigated by comparing the analytical solutions with the numerical output for flow in the coaxial cylinders. This effect was studied by ... Mehr lesen
In order to qualify experiments for in-vessel irradiation at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, safety assessments need to be completed and documented to ensure adequate target cooling and structural integrity. Previously, finite element analysis ... Mehr lesen
