numerical investigation of sheet cavitation on dtmb4119 marine propeller, using boundary element method, based on potential flow assumption

in this work, a numerical study of sheet cavitation has been performed on dtmb4119 marine propellers, using boundary element method (based on potential flow assumption). in propeller design, various parameters of geometry and flow are incorporated. so, a computer program is needed to take all parameters into account and solve the flow. capability of analyzing the wetted and cavitating flow around propellers in steady, unsteady, uniform, and non-uniform conditions, while decreasing of computational time, with acceptable precision, are the characteristic features of the present work. moreover, modifying the position of the detachment point and its corresponding potential value have been considered. numerical results have been validated with experimental data, showing satisfying agreements.
