Abstract EN
The spatial fluctuating pressure field (FPF) of counter rotating propeller (CRP) under noncavitating condition is investigated.
The hydrodynamic performance and pressure distributions on the blade surfaces are obtained through low-order potential-based panel method, which is also used to analyze the hydrodynamic interaction between the front and rear propellers of CRP as well as the hydrodynamic interference between any solid surface and propeller.
The interaction between the given solid spherical surface and propeller is used to simulate the spatial FPF of propeller, and the fluctuating pressure induced by a propeller over one revolution is analyzed in frequency domain through fast Fourier transform.
The method proposed is validated through two given propellers by comparing the calculation results with test data.
The FPFs of the front and rear propellers are calculated and compared with that of the corresponding single propeller.
The result shows that the CRP produces weaker FPF compared with the single propeller.
