To reduce drag and relieve the pressure wave in the hyperloop system, compressor was mounted at the front of the pod. Two-dimensional axisymmetric simulations were conducted, and overset mesh method was applied for moving mesh simulation. The length of the hyperloop tube is 1200 m, the diameter is 5 m, the length of the pod is 43 m, the diameter is 3 m, and the diameter of the compressor is 2 m. To compare the effectiveness of the compressor, three different compressor capacities were applied for each speed of 250 m/s, 300 m/s, and 350 m/s. Ansys Fluent software was used to proceed with the interpretation, and a turbulent model based on the RANS model was applied. It was found that the larger the compressor capacity, the more relaxed the flow of the surrounding compressor and the less drag compared to the without compressor cases.
