Numerical simulation of temp. distributions in outlet streams from chimneys of turbines was carried out on the example of a gas compressor station in Ciechanow equipped with 3 turbo compressors with a capacity of 25 MW each. The 3-D numerical model was developed by using the corm software for computational fluid dynamics. The anal. were carried out for various weather conditions (winter, summer) and for different wind speeds (0, 5 and 10 m/s) measured at the height of the chimney outlet. The objects flying 100 and 200 m above the chimney outlet were exposed to contact with exhaust gases at 80 and 40 degrees C, resp.
