In order to adapt to the working characteristics of gas turbine generator sets for offshore platforms, taking a 300 kW gas turbine generator set as an example, a numerical simulation study on ventilation in a sound attenuation enclosure is carried out. In order to improve heat dissipation performance, the gas turbine generator set adopts a subdivision design. The calculation results show that the total pressure loss of the generator room is 851 Pa, and the inlet and outlet temperature rise is 7.4 ℃. The total pressure loss of the core engine room is 454 Pa, and the inlet and outlet temperature rise is 7.6 ℃. The airflow has abundant heat exchange, and the pressure loss is low, which can meet the use conditions of the gas turbine generator sets for offshore platforms.
