Numerical Simulation for Aerodynamic Behaviour of Hyperloop Capsule and the Influence of Wing and Spoiler using CFD

摘要

Hyperloop is a new transportation concept in which capsule travels in a lower pressure seal tube. For an hyperloop capsule, wing and spoiler mounted to investigate the effect at different deployment angles 30° 60° and 90°. In this paper, the wing is designed to increase the aerodynamic drag base brake force and downforce by the pressure difference on the wing. The spoiler is designed to increase the downforce by deflecting the airflow at the rare of the capsule. Prototype hyperloop capsule, wing and spoiler are modelled using CATIA V5-6R 2018 software and numerical analysis is carried out using ANSYS CFX 2021 R1 software for all aerodynamic setups. The study of wing and spoiler with different deployment angles on the hyperloop capsule can be utilized to enhance the aerodynamic drag base brake force and downforce performance of the hyperloop capsule. A detailed comparison is presented between the regular capsule, capsule with wing, capsule with spoiler and capsule with both wing and spoiler. Using a wing and spoiler with different deployment, angles on the capsule is more effective than the regular capsule.
