Bellmouth system
The bellmouth system in a large gas turbine performance testing facility is equipment used to measure the airflow rate drawn into the gas turbine. It is an essential component for evaluating gas turbine performance, and based on Bernoulli's principle , it provides critical data for optimizing the gas turbine engine's performance and increasing its efficiency. /
Bell-mouth Nozzle Based on inner diameter, Inlet φ 1940.6 x Throat φ710 x 1420 mm
Diffuser for Bell-mouth Inlet φ 710 x Outlet φ1420 x 5000 mm

In 2017, Gasroad designed and manufactured a large bellmouth system to measure the intake airflow rate of a 300MW large gas turbine engine. A mass flow rate calculation formula was derived, and after testing and calibration for verification in a wind tunnel at CEESI in the United States, the flow coefficient was corrected.
In 2022, Gasroad manufactured nine large bellmouth systems, arranged in a 3 by 3 configuration, for the gas turbine engine test facility at Doosan Enerbility. These systems are now being used in measuring air intake of the gas turbine engine and airflow rate of the load compressor.
