<p>This study aims to explore behavior of MHKF-180s hydrofoils in both unsteady cavitating and non-cavitating flows using Realizable <i>k</i>&#xa0;−&#xa0;<i>ϵ</i> turbulence model and Zwart–Gerber–Belamri cavitation model at different angles of attack for a Reynolds number of 1.3 × 10⁶. First of all, the performance of two different cavitation models and four different turbulence models are compared with experimental results available for NACA4412 and Clark-Y hydrofoils. In addition, the hydrodynamic performance of cavitating MHKF-180s hydrofoil is examined across various Reynolds numbers (ranging from 1.1 × 10⁶ to 2.6 × 10⁶) at different angles of attack. The performance is assessed based on parameters, such as lift coefficient, drag coefficient, lift-to-drag ratio, pressure coefficient, cavity shedding, frequency of oscillating cavity etc. Among all the turbulence models, Realizable <i>k</i>&#xa0;−&#xa0;<i>ϵ</i> model stands out to be more precise and reliable. This model captures the flow separation, vapor shedding and vortex shedding more precisely. Furthermore, the hydrodynamic performance of cavitating MHKF-180s hydrofoil is found to be consistent regardless of the Reynolds number. On comparing the performance of cavitating and non-cavitating MHKF-180s hydrofoils, it is observed that cavitating hydrofoil exhibits lower lift, higher drag, and a decreased lift-to-drag ratio, resulting in reduction of the hydrodynamic performance for cavitating case.</p>
