Abstract This paper presents the development of a new Graphics Processing Unit (GPU) accelerated computational tool for asteroid disruption techniques. Numerical simulations are completed using the high-order spectral difference (SD) method. Due to the compact nature of the SD method, it is well suited for implementation with the GPU architecture, hence solutions are generated at orders of magnitude faster than the Central Processing Unit (CPU) counterpart. A multiphase model integrated with the SD method is introduced, and several asteroid disruption simulations are conducted, including kinetic-energy impactors, multi-kinetic energy impactor systems, and nuclear options. Results illustrate the benefits of using multi-kinetic energy impactor systems when compared to a single impactor system. In addition, the effectiveness of nuclear options is observed.

    Highlights An asteroid disruption computational tool is developed on GPUs. High-order methods are applied to asteroid disruption problems. Spectral difference is integrated with the Diffused-Interface Model. Multiple kinetic impactors are more effective than single impactors. Nuclear explosives are most effective at asteroid disruption.
