Abstract
  • This paper deals with the analysis of the flow field around a tug boat advancing in calm water. The main goal of the ongoing project, of which this work is part, is the characterization of the hull wake and in particular of the inflow to the propeller; to this aim, two operating conditions, at low and high Froude number, at both model and full scale Reynolds number are simulated for the propelled and unpropelled tug boat. The analysis is carried out by using numerical simulations based on the RANS equations; free surface is handled by means of a one-phase level set approach, propeller effects are taken into account by a non-iterative body-force model. Some preliminary results in terms of velocity flow field and wave pattern are presented. (literal)
