This paper evaluates the flow field characteristics of a bottom-supported aquaculture platform under uniform flow based on numerical simulation and model experiments. A numerical method combined with the realizable k-å turbulence model and the porous media model is established to describe the flow. The fish net is simplified by a porous media and the main framework is modelled as rigid wall conditions. Model tests are conducted, and the experiment data validate numerical simulation results, exhibiting good agreement. The influences of some key parameters on the flow field are investigated by the present numerical model, such as incoming flow velocity, angle of attack, and with or without nets. The findings highlight that the double-layer nets will promote velocity attenuation and create a low-velocity wake region downstream of the platform. Conversely, the impact of the bottom fish net on the velocity attenuation is deemed insignificant. The angle of attack has an obvious effect on velocity distribution but has little effect on wake width, and a higher incoming flow velocity will lead to greater velocity attenuation. It should be noted that the tail vortices generated by the oversized centre column may affect the flow field and structural safety.
