In this poster, a numerical model of spot pulsed current TIG welding for partially and fully penetrated weld pools is presented. Heat transfer and fluid flow in the weld pool driven by the combination of electromagnetic force, buoyancy force, surface tension gradient and latent heat are ... Per saperne di più
Fiber optic sensors can measure a large range of physical, chemical and environmental variables such as temperature, pressure, shape, position, chemical concentration, moisture, etc. Fiber optic sensors provide measurements in applications where the conventional electrical based sensors ...

The majority of electrical machines are designed to produce the rotary motion, there by exploiting the blessing of circularity which man has enjoyed since the discovery of the wheel. Electromagnetic forces may also be employed to produce the linear motion resulting in linear motion ... Per saperne di più
Most probably Gauss\'s law is considered as the first \"electromagnetic\" concept for early undergraduate physics and electromagnetic courses. In early study year, teaching Gauss’s law is usually performed based on two main components; 1) The use of simple symmetrical charge ... Per saperne di più
Using COMSOL Multiphysics, a finite element model is introduced in this paper to describe the couplings between the welding arc and the weld pool dynamic in pulsed gas tungsten arc welding. The cathode, arc-plasma and melting anode regions are taken into account. The unified time ... Per saperne di più
This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... Per saperne di più
The waveguide device modeled here specifically demonstrates the exploration of a small, but very important, subset of components of the family of microwave hardware devices designed to facilitate the optimized transfer of power from the generating source to the consuming load. Each of ... Per saperne di più
High power Terahertz (THz) sources have become a topic of great interest for a wide variety of applications from medical science to security systems and from material science to telecommunication. The high output power of these THz sources mainly depends upon high current density and ... Per saperne di più
电声产品测试为了更贴近于实际人耳感受到的灵敏度，通常测试时会带上一个耦合腔来模拟耳道的情况，使麦克风测试到的声压更接近于人耳感受到的声压。目前测试较为普遍配合的耦合腔一般有711高漏仿真耳耦合腔、711低漏仿真耳耦合腔和318仿真耳耦合腔。电声产品经过不同的耦合腔测试会在整个频段体现出不同的声压级，设计电声产品的前期，需要了解到不同耦合腔是否可以满足设计需求。使用COMSOL可以对细窄管道和狭缝区域模拟分析，将耦合腔的特性准确仿真模拟出，有效预知电声产品经过耦合腔之后的性能特性。 Per saperne di più
Position sensors have several applications in the automotive sector. Some of the common examples include automatic gear shifter module, seat position adjustment and accelerator-pedal position modules etc. Because of extreme weather condition, such as dust, humidity and moisture and ...
