<b>Abstract.</b> In this paper the vortex cloud method is used in an attempt to simulate the viscous flow through linear cascades. As the flow is periodic in the y direction, the discrete vortex-shedding need only be considered for a reference airfoil. The Vortex Method is also modified to take into account the sub grid- scale phenomena; a second-order velocity structure function model is adapted to the Lagrangian scheme. The dynamics of the airfoil wake is computed using the convection-diffusion splitting algorithm, where the convection process is carried out with a Lagrangian second order Adams-Bashforth time-marching scheme, and the diffusion process is simulated using the random walk scheme. In this study, the pressure distribution is obtained using the integral equation derived from the pressure Poisson equation. Flows around NACA 65-410 serie airfoils are calculated and comparisons are made with experimental studies for pressure distribution and linear cascade deflection angle.
