摘要

This study validates a set of proposed design improvement methods for inland oil tankers and passenger ships in Bangladesh’s inland waterways. Hydrodynamic performance is assessed using computational fluid dynamics (CFD) simulations. Three-dimensional models of three oil tankers and three passenger ships are created after physical investigations and measurements. These are reconfigured according to previously suggested qualitative and quantitative design recommendations. The CFD analysis results indicate very significant reductions in overall resistance for all the redesigned vessels, ranging from 5.56% to 17.27% for oil tankers and up to 16.97% for passenger ships. These reductions validate the effectiveness of the proposed design methods in improving energy efficiency. Although limitations due to operations are present with some of these recommendations, the overall performance improvements provide valuable insights for enhancing the designs of inland ships. However, to validate such computational findings and expand design processes, model testing of new designs is recommended.
