This study aims at the accurate numerical simulation of hypersonic flow created by multiple disintegration of expired spacecraft re-entering into near space. Taking the Tiangong-1 spacecraft as an example, we conducted flow simulation calculations for the compartment. We also conducted numerical simulations for the multi-body flow around the debris of the Tiangong-1.
