Abstract
One of the key purpose in water propeller design is to determine operating conditions where the cavity mode appears. They may result in dramatic thrust lack, drag rise and mechanical damage. An objective of the article is to verify potential of computer fluid dynamics program set OpenFoam in 5-bladed propeller propulsion characteristics investigation next to the cavity mode, and to study pitch and maximum thickness roles in cavity sustainability. Applied in the work method is based on solution of Reynolds equations with turbulent model closure via finite volume method. Suggested methodology proved a high conformity to experimental data.
