Due to the particularity of the working fluid and extreme aviation conditions, dissolved gases （DG） are important factors that cannot be ignored in fuel cavitation. To reveal the independent mechanism of DG in the cavitation process, the cavitating flow characteristics around a two-dimensional Clark Y-11.7% hydrofoil in room-temperature water were investigated. Particular attention was paid to the convection-diffusion behavior of dissolved oxygen in liquid water as well as the dissolution/degassing processes. Using the Clark Y-11.7% hydrofoil as the research object, an in-depth exploration of the influence mechanism of DG on the fundamental cavitation of a hydrofoil was performed. Within the framework of the Schnerr-Sauer （SS） cavitation model, the convection-diffusion effect and dissolution/degassing processes of DG were coupled to establish the SS-DG cavitation model. Numerical simulations of hydrofoil cavitation were then conducted using this model. Combined with experimental results, the effects of DG on cavitation structures and hydrodynamic characteristics were analyzed in detail under two angles of attack (8° and 20°) and three different dissolved oxygen concentrations. The results showed that different concentrations of dissolved oxygen in the liquid altered the cavity structure near the leading edge of the hydrofoil. Under both angles of attack, the average lift and drag coefficients were only slightly affected by dissolved oxygen concentration, but its presence modified the unsteady characteristics. In addition, due to large-scale flow separation, the time-averaged dissolved oxygen concentration in the cavitation region at a 20° angle of attack was significantly higher than that at 8° under the same conditions.
