<p>Hyperloop is a next-generation transportation system plan that is currently being developed which is a railroad running in a tube with reduced pressure. In this research, we aim to understand the behavior of the capsule and to investigate the running stability by numerical analysis of the flow field inside the Hyperloop tube. In this study, the tube is moved at high speed in numerical calculation and the internal flow field is examined. Calculation is performed considering compressibility in non-steady computation. In addition, each parameter was calculated from the relational expression of the shock wave whose Mach number was changed and given as a condition. In the process of calculation, we changed the total pressure applied and verified in which condition shock waves occur in the tube. Also, we investigated the effects on the capsule due to the changed Mach number and the change in the speed, and made it a basic research to examine the running stability of the Hyperloop.</p>
