Contactless inductive flow tomography.
The three-dimensional velocity field of a propeller-driven liquid metal flow is reconstructed by a contactless inductive flow tomography. The underlying theory is presented within the framework of an integral equation system that governs the magnetic field distribution in a moving electrically conducting fluid. For small magnetic Reynolds numbers this integral equation system can be cast into a...
متن کاملContactless Inductive Flow Tomography: A Liquid Metal Flow Measuring Technique Complementary to UDV
The aim of the Contactless Inductive Flow Tomography (CIFT) is the reconstruction of flow structures in metal and semiconductor melts. It relies on the induction of electric currents in moving conductors exposed to magnetic fields. The flow induced deformations of various applied magnetic fields can be measured in the exterior of the melt and utilized for the reconstruction of the velocity fiel...
متن کاملContactless Inductive Bubble Detection in a Liquid Metal Flow
The detection of bubbles in liquid metals is important for many technical applications. The opaqueness and the high temperature of liquid metals set high demands on the measurement system. The high electrical conductivity of the liquid metal can be exploited for contactless methods based on electromagnetic induction. We will present a measurement system which consists of one excitation coil and...
متن کاملDirectional Tuning Control of Wireless/Contactless Power Pickup for Inductive Power Transfer (IPT) System
Inductive Power Transfer (IPT) systems have successfully been developed and used to replace traditional conductive power transfer systems where physical connection is either inconvenient or impossible, such as biomedical implants, undersea vehicles, and contactless battery chargers of robots, for providing power to movable or detachable loads (Kim et al., 2001; Feezor et al., 2001; Harrison, 20...
متن کاملContactless Impedance Sensors and Their Application to Flow Measurements
The paper provides a critical discussion of the present state of the theory of high-frequency impedance sensors (now mostly called contactless impedance or conductivity sensors), the principal approaches employed in designing impedance flow-through cells and their operational parameters. In addition to characterization of traditional types of impedance sensors, the article is concerned with the...
