N2 - The uniform flow around a square cylinder at Reynolds number 1e5 is simulated in a threedimensional domain by means of the newly developed Self-induced angular Moment Method, SMoM. The model does not utilize Reynolds averaging. No additional transport equations are introduced and no implicit or explicit filtering is performed. The model is, in all its simplicity, a modification of the classical constitutive equations of fluids to which a term is added that accounts for the transfer for angular momentum between parts of the fluid.The time-mean and fluctuating force coefficients, pressure distributions and velocity fields have been determined along with circumferential surface pressure correlations. All simulated quantities have been compared to experimental findings and state-of-the-art Large Eddy Simulations, LES. No LES simulations could be found in literature, which provided results at the same level of accuracy for all the reported parameters. Hence, the SMoM turbulence model is found to provide an alternative to the Large Eddy Simulations.
