EFFECT OF AN ACCOMMODATION SHAPE ON AERODYNAMIC PERFORMANCE AND REDUCED AIR RESISTANCE ACTING ON A CARGO RIVER SHIP

Abstract

In this paper, the authors present some results of studies on aerodynamics performances and the effects of an accommodation shape on the aerodynamic performance of a cargo river ship. From results of analysis aerodynamic performances of the ship, several comments and proposed new hull form for the ship to reduce wind resistance is done. A popular kind of the cargo river ship which is almost used at currently river transportation on the northern Vietnam river is selected as a reference model. From the results of analysis computed results on aerodynamic performance of the original ship, several new hull form with improving accommodation shape are proposed for the ship to improve aerodynamic performance and reduced air resistance acting on the original ship. The results of this research are needed to help optimize the aerodynamic hull shape as well as reduce air resistance acting on hull, reduced fuel consumption and improve economic efficiency of the ship operation.
