Composite systems are becoming more and more widespread across industries and the capability to finding and tracking internal defects before they have grown to major deterioration is of paramount importance in regard to safety, economy and maintenance. We are exploring a novel method of ... Per saperne di più
In a magnetic resonance imaging (MRI) system, it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires a coupling between the nuclei and a source of radio frequency (RF) power using a transmitter. To receive a meaningful signal, we also need ... Per saperne di più
Increasing demand for new technology, products and processes to provide improved performance, achieve proof of concept quicker, offer higher quality and meet demands for on-time and on-budget delivery have put increasing pressure on scientist and engineers to predict performance before ...

Small-scale plasma jets in atmospheric air can produce regions of highly reactive chemistry coincident with temperatures approaching room temperature allowing his type of cold plasma jet to be used for decontamination of surfaces and sterilization of living tissue. In the device under ... Per saperne di più
Necrosis of human tissue can typically be obtained by exposure to temperatures below 40°C or above +50°C. However, inherent variability in tissue properties, the complexity of tissue response and dissipation of thermal energy by local perfusion or blood flow can make the development of ...

Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... Per saperne di più
A prominent technological goal at the National High Magnetic Field Laboratory (NHMFL) involves developing high temperature superconductors (HTS) for use in nuclear magnetic resonance (NMR) at fields above 31 T. Work presented here demonstrates the extensive use of finite element ... Per saperne di più
In optogenetics research it is highly desirable to have a method that can deliver light and excite individual neurons in the brain in a controllable and single cell manner. Working toward this goal, we are developing liquid microlenses with active electronics that enable both focusing ... Per saperne di più
A finite element model for underground corrosion is presented. The model is capable of predicting regions experiencing high levels of corrosion due to differential aeration and helps identify "corrosion hotspots" where physical examination of the buried asset is not feasible. ... Per saperne di più
激光沉积是激光增材制造的一种,激光照射靶材表面,同时合金粉末同步送入工件表面,激光与粉末相互作用,并在基体表面形成金属熔池,随着热源和粉末流的相对移动,熔池快速冷却,形成沉积道。该快速熔凝过程复杂,涉及传热(热传导与热对流)、流动、相变、质量添加、多组分传质、自由表面移动等。 本算例使用了传热模块、流动模块和组分传输模块,研究激光增材制造过程中的高温金属熔池的温度场、速度场和浓度场。分析表面张力、重力、等对熔池形成的影响;引入液相分数描述固液糊状区,在动量方程和能量方程中添加源项建立固液混合区的控制方程;采用动网格技术(ALE)实现移动自由界面 ... Per saperne di più
