Multiphysics simulation of an anisothermal reactive spontaneous capillary rise between electric rotor wires

Introduction: The rotor is the mobile component of an electric motor. A wound composed primarily a steel core with insulated copper wires around it, after which winding immersed into liquid acrylate-based thermosetting resin bath whose role to ensure performance and durability This impregnation between occurs under controlled temperature settings facilitate flow polymerization. process does not involve any pressurization further wires; this suggests that, in addition viscous effects, capillary gravity forces play significant process. Methods: Our ultimate objective evaluate quality impregnation. Doing so requires characterization simulation multi-material multiphysics heat transfer, polymerization kinetics, are strongly coupled. paper presents fully coupled macroscopic unidirectional thermo-regulated rise set-up. Discussion: modeling choices made produced good level agreement experimental data enable explanation sudden change regime observed at 120°C, can be attributed thermal gradients their impact on fluid dynamics.
