Cooling effects inside water-cooled inductors for Magnetic Fluid Hyperthermia

What is it about?

The paper lists several well-known formulas for on-axis magnetic field inside ideal solenoid and compares them with the values obtained from the computer simulation of the actual water-cooled coil for magnetic fluid hyperthermia (MFH) purpose. Performed analysis of coupled electro-thermal problem using finite element method (FEM) may led to the estimation of impact of heat losses due to water cooling on temperature within a region of interest (ROI) for some important model parameters. It is shown that cold water circulating inside the copper windings cause significant cooling of such inductors. What is important, it enables convenient conditions for ferrofluid testing and reliable operation of temperature sensors placed inside helical coils.
