Computation of Propeller-Hull Interaction using Simple Body-Force Distribution Model Around Modified Series 60 CB = 0.6 Hull with Hub

A 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 around Series 60 CB = 0.6 hull. The hull form is modified with the stern tube and the hub; and the propeller is a right-handed 5 blade fixed pitch Modified-AU methodical series type which is treated as infinite bladed model. In this paper as an extended research of Win et.al (2013), the detailed flow field in the wake region is observed and the effect of the existence of the rotating hub in the computation of the propeller is analyzed.
