Geometrical Similarity Criterion for Electromagnetic Drives Magnetic Systems with respect to Permissible Heating Condition

Abstract

The paper presents the results of investigation of geometrically similar magnetic cores of electromagnetic drives magnetic systems with respect to heating conditions. As a result, the geometrical similarity criterion has been obtained. This criterion is a non-linear function of cooling surface and electromagnet volume. It simplifies design optimization procedures when volumes are different in typical variants of magnetic systems. The geometrical similarity criterion has been tested by means of magnetic field simulation.

Development and Application of an Ultrahigh‐Temperature Steam Generator

“…e forming process of polymer materials mainly includes injection molding, extrusion molding, blow molding, rotational molding, and other molding processes [1][2][3]. However, temperature control is an important condition and key parameter in the formation of all macromolecule materials [4][5][6]. Steam generator is a mechanical device that uses heat energy to heat water into hot water or steam.…”
