Abstract
The simple body-force distribution model by quasi-steady blade element theory is coupled with the Reynolds averaged Navier-Stokes (RANS) code CFDSHIP-IOWA to study the propeller-hull interaction. The ship model is Series S60 (CB = 0.6) ship model without hub, without rudder and the propeller is a right-handed 5 blade fixed pitch Modified-AU methodical series type which is treated as infinite bladed model. Computations are performed for the ship sailing straight ahead with- and without propeller. In the without propeller case, the bare-hull results are made sure for confirmation with the experimental data to prove the magnitude of the flow field quantities with fair agreement. The computations are performed while the propeller model is working on various propeller loadings and the results of propulsive performances and flow fields in the wake regions are compared with the EFD data.Summarizing the results, the present propeller model proves its capabilities on the studies of propeller-hull interaction with much less computational effort and verifies its possibility for the load varying case.
