| Summary: | The problem of ensuring a uniform velocity field at the air inlet to the first stage of the gas turbine compressor SGT5-2000E with an angular inlet path, that contains an inlet filter, a silencer and an angular intake flare, is considered. Based on the mathematical modeling of the flow in this flare, it was found that the maximum speed at the compressor inlet is 36% higher than the average flow rate. It leads to the fact that the range of stable operation of the compressor seriously narrows. To solve this problem, it is proposed to change the intake flare design so that a newly developed effective damper of uneven velocity fields is installed in its flow part. Studies have shown that in this way the nonuniformity coefficient was reduced from the above 36% to 6%.
