Comparison of Machine Learning Models Based on Different Ship Hull Form Representations for Hydrodynamic Performance Prediction

Accurate prediction of ship hydrodynamic performance is essential for hull form optimization during the early design stage. This study investigates two approaches for incorporating ship hull geometry into machine learning-based surrogate models using offset data. The first approa...

Topological Analysis of Turbulent Wake Behind a Trapezoidal Mixing Tab Using DES and Velocity Gradient Tensor Invariants

This study numerically investigates the complex three-dimensional turbulent flow around a trapezoidal mixing tab, which acts as a vortex generator in an infrared signature Suppression System(IRSS). While previous studies heavily relied on steady Reynolds-averaged Navier-Stokes(RA...
