A numerical simulation of high-Reynolds-number opposed impinging wall water jets in a limited field
AIP Advances, 2023 In the impinging region of opposing jets, strong mixing and significant energy dissipation are observed, but the mixing parameters invariably change with the opposed impinging strength (OIS). In this paper, the ratio of the turbulent kinetic energy (TKE)
