Simulation of aerodynamic performance of a symmetrical micro airfoil using dissipative particle dynamics method

This paper uses the dpd method to simulate the flow around a microairfoil. In this study, periodic boundary conditions were used, and the particles were balanced by applying these boundary conditions. The results include the analysis of velocity profiles in simple channel geometry and the comparison of flow simulations in channels by dpd and cfd. The error of comparing the velocity profiles with these two methods was 6%. Next, the flow around the rhombus-shaped airfoil was simulated, and with the expansion of the flow around the airfoil, the pattern of flow lines was obtained symmetrically. The results for naca0012 airfoil also expanded to 5 different angles. The diagram of aerodynamic coefficients and the diagram of aerodynamic force ratio in terms of attack angle has been compared with two simulation methods of dpd and cfd. The comparison error of these two methods was calculated to be less than 3% .
