Heat Transfer and the Formation of Vapor Bubbles When Boiling a Magnetic Fluid on a Single Center of Vapor Formation in an Alternating Magnetic Field

Abstract

The frequency of vapor bubble formation and heat transfer when boiling a magnetic fluid in a homogeneous alternating horizontal magnetic field are studied experimentally. Bubbles form on a single center of vapor formation. The induction current in the coil through which the vapor bubbles move is used to measure the frequency of vapor bubble formation. It is found that the specific heat flux and the frequency of vapor bubble formation depend strongly on the frequency of the magnetic field. Results testify to the possibility of effective non-contact control over the boiling of a magnetic fluid, which could have practical applications.
