압축기 장착한 하이퍼루프의 포드 형상에 따른 변화 연구

다국어 초록 (Multilingual Abstract)

A hyperloop, the high speed train operating in low pressure tunnel, can overcome the effect of chocking and improve the aerodynamic performance by using axial compressor. This paper studies the effects of the compressor equipped hyperloop pod’s shape change on the power total (required amount of power to operate a hyperloop system) using CFD. The compressor was modeled with fan boundary condition and all simulations are implemented at the predetermined blockage ratio, pod mach number and intensity of compressor. The area ratio of duct and pod (K<SUB>A</SUB>) and the height of tail (Tail<SUB>Lν</SUB>) are chosen as parameteric variables and the simulations are conducted by varying these values. As K<SUB>A</SUB> increases, the compressor mass flow rate increases, which leads to the decrease of pressure at frontal pod and power total. From the simulation results, as K<SUB>A</SUB> increases, the height of pod’s tail that minimizes its power total also increases.
