In order to study the aerodynamic resistance characteristics of the intake system in a new marine gas turbine and explore the innovative design, the experiment investigation was carried out on the original intake system under the design condition, on which the aerodynamic parameters were collected. Meanwhile, the numerical simulation software ANSYS CFX was used to obtain the flow field of the intake system at the same condition in detail, thus both the distributions of the total pressure loss and the aerodynamic resistance characteristic for the different cross sections were analyzed. Results show that the simulated aerodynamic parameters were well agreed with the experimental data. The internal flow field of the main flow of the intake system keeps stable and uniform in the design condition, and the total pressure loss of different parts allocation is reasonable. The overall total pressure loss is 1242.17 Pa, the resistance coefficient is 21.30, the outlet uniformity coefficient is 0.9989, and the aerodynamic resistance is lower. Thus, the synthetic simulation text-bed has good aerodynamic characteristics.
