하이퍼루프 시스템의 열전달특성 및 전기열원의 냉각방법에 대한 수치해석

초록

Hyperloop is a transportation system that utilizes a near-vacuum tube where a transport capsule is propelled by the magnetic force of the propulsion coil at high speeds. The linear induction motor applies a current to the propulsion coil to generate a magnetic force, and this process generates heat due to Ohmic loss, which raises the coil temperature. Consequently, coil resistance increases, leading to energy loss due to Ohmic loss and increasing the required voltage to maintain the propulsion force. Therefore, studying the heat transfer characteristics and cooling solutions for the electrical heat source inside the hyperloop is essential for thermal stability and energy efficiency. To address this, a numerical analysis was performed to evaluate the heat transfer characteristics of the electrical heat source and cooling solutions. We constructed an analysis model for the heat transfer of the electrical heat source in the hyperloop system. Furthermore, passive and active cooling solutions for the propulsion coil were developed and assessed for their heat transfer characteristics and cooling effects, considering the system characteristics.
