Tools for Education in Eddy Currents
نویسنده
چکیده
The paper presents two tools for teaching the basics of eddy current inspection. The first tool is a semi-quantitative simulation code showing the correspondence between probe action and signal behaviour. The student guides a virtual probe over a virtual workpiece with different defects. The measurement immediately appears in the normalized impedance plane. The second tool is a complete eddy current instrument plugged to the USB-port of a PC or notebook. Absolute and differential probes permit to inspect reference pieces with typical defects and material properties. The signal is displayed in the complex plane directly on the monitor. The current setting and the recorded signals may be included in a report automatically. Single and dual frequency modes are available. These tools help the teacher to explain eddy current fundamentals via notebook and data projector. The student gets interactive tools for theoretical and practical training. Additionally EddyCation permits to test eddy current inspection method for new tasks.

Boundary Shear Stress in a Trapezoidal Channel
This paper focuses on a hydraulic radius separation approach used to calculate the boundary shear stress in terms of bed and wall shear stress proposed in a trapezoidal channel. The average bed and sidewall shear stress in smooth trapezoidal open channels are derived after using Guo & Julien (2005) early equations taking a part of an investigation to cover both rectangular and trapezoidal chann...
متن کاملA new strategy for controlling wind turbines against sensor faults and wake effects to harvest more electrical energy
This paper describes a new method for harvesting maximum electrical energy in wind farms. In proposing technique, the stochastic process principles are applied for detecting fault measurements of sensors. On the other hand, the wind farm is modeled by using fuzzy concept. Thereby the turbines are controlled against continuous changes in speed, direction and eddy currents of the blowing wind. To...
متن کاملEmploying dual frequency phase sensitive demodulation technique to improve the accuracy of voltage measurement in magnetic induction tomography and designing a labratoary prototype
Magnetic induction tomography (MIT) is a promising modality for noninvasive imaging due to its contactless technology. Being a non-contact safe imaging technique, MIT has been an appropriate method in compare to other electrical tomography. In this imaging method, a primary magnetic field is applied by excitation coils to induce eddy currents in the material to be studied and a secondary magnet...
متن کاملEstimation of salinity, heat and buoyancy budgets of the inflow coastal current into the Persian Gulf from the Strait of Hormuz
An analytical model for a coastal boundary current was used to investigate heat and salt budget of exchange flows in the Persian Gulf as a marginal sea. Coastal boundary currents exchange heat and freshwater with the mosphere and the offshore waters. As heat and salinity fluxes caused by air-sea interaction and eddy activities, different temperature and salinity associated with boundary current...
متن کاملImproved Slice Excitation for Ultra-short TE Imaging with B0 and Linear Eddy Current Correction
INTRODUCTION MR imaging with ultra short echo times (UTEs) are of increasing interest to visualize tissues with short T2 or T2*, such as cartilage and ligaments, or monitoring the temperature during cryosurgery [1]. To achieve ultra-short TEs, a self-refocused half RF is usually used for excitation [2]. However, eddy currents induced by the selective gradient can result in undesirable slice pro...
