TL;DR: Pudsey et al. as discussed by the authors performed a three-dimensional numerical study of the effects of sonic gaseous hydrogen injection through multiple transverse injectors subjected to a supersonic crossflow.

TL;DR: The fundamental flow physics of the interaction between an array of fuel jets and a hypersonic boundary layer is investigated in this article, where hydrogen is injected at jet-to-freestream dynamic pressure ratios ranging from 0.350 to 0.875 on a flat plate into a Mach 4.5 crossflow.

TL;DR: In this paper, numerical simulations were carried out to determine the sensitivity of results to a variety of geometric and flow parameters commonly employed in high-speed transverse jet-interaction calculations, including turbulence model, freestream turbulence intensity, turbulent Schmidt number, and several injector-pipe configurations.

TL;DR: In this paper, a numerical study was performed to investigate the film-cooling drag reduction performance of a small-scale multiport injector array, in addition to its potential for improved boundary-layer combustion-induced drag reduction.

TL;DR: In this paper, the authors investigated a geometry in which the cavity is placed directly upstream of the injector and examined its effect on scramjet combustor mixing performance, and found that increased shielding provided by the cavity was found to enhance mixing by up to 9%.
