In this work, two algorithms for synthetic turbulent inflow generation are implemented within a modern transport-velocity SPH framework. Both methods are tested using three-dimensional simulations of convected isotropic turbulence with prescribed turbulence characteristics, including length scale, time scale and fluctuation intensity. The capability to model anisotropic turbulence is further assessed by simulating turbulent flow in a circular pipe. Near the turbulent inlet, a high agreement with the prescribed statistics is achieved. Coherent structures are successfully formed and exhibit realistic downstream evolution, demonstrating promising potential for future applications to more complex scenarios, such as shear-driven liquid atomization.
