Research on the Temperature Filed Distribution Characteristics for Thermal Management of Coilgun

Ohmic heating has become one of the main factors restricting their efficiency and longevity of the synchronous induction coilgun (SICG) operating in a complex electromagnetic environment. Therefore, further exploration on the temperature spatial-temporal distribution characteristics of the SICG is of great practical significance to ensure its reliable and efficient operation. The single-stage SICG is taken as the research object to simplify the solving process. First, the effectiveness and accuracy of the numerical simulation models in terms of kinetic and thermodynamic properties are compared and verified. Then, the influence of different structural parameters on temperature rise and acceleration is investigated in detail. The conclusions can not only provide theoretical reference for the long-term service of the SICG but also guide the related research of continuous emission.
