The paper presents results of large eddy simulations (LES) of flows around two different pyramids with apex angles of 60^o and 90^o. The pyramids were studied in flows with a zero yaw angle with respect to the incoming flow. The results of our simulations were compared with the existing experimental data, showing good results. Both time-averaged and instantaneous flows resulting from LES were investigated in detail and used to confirm or extend previous knowledge about flows around pyramids.
