The focus of the paper is on the numerical simulations of flows at low Reynolds number at subsonic Mach numbers. The interest for the compressible aerodynamics of low-Reynolds number flow has recently grown for the possible use of aircrafts for exploring the Martian surface. Large eddy simulations have been performed for the flow around the NACA 0012-34 airfoil at low Reynolds number and Mach numbers varying from 0.20 to 0.61. The achieved results are compared to reference data available in literature. The focus is on the role of the Mach number and in particular on the behaviour of the lift coefficients that do not follow the classical compressibility rules.
