“…In contrast to the ITTC correlation lines, the frictional resistance depends not only on Re but also on hull type and H T . Zentari et al (2022) also concluded that C F increases when the water depth decreases, especially when H T ≤ 2.0, thus indicating that the conventional ITTC method might underestimate frictional resistance in shallow water. For the vessels whose hull shapes differ from the reference significantly, a "virtual ship method" is utilised to include the effect of shape changes on resistance, as shown in Fig.…”

“…Friedhoff et al (2019) conducted an experiment using a Particle Image Velocimetry (PIV) test to investigate the effect of water depth on the wake fraction of a large Rhine vessel in different stern shapes. In addition, Zentari et al (2022) conducted systematic model tests to investigate the resistance and propulsion of different arrangements of pusher-barge convoys to study the confinement effect on inland vessels.…”

“…In addition to the single self-propelled inland vessel, the study also investigated resistance prediction for pushed convoys using the ship model test results from the literature; the hull geometry and detailed experimental data is available in Zentari et al (2022). This experiment included three types of barge arrangements: Convoy 1:1, Convoy 2:1, and Convoy 2:2.…”

“…In the ship resistance issue, the average value of the force should be emphasized. Using the term "turbulence model," the RANS method simulates turbulence and provides time-averaged values for velocity and pressure [30]. Therefore, it requires less time and fewer computational resources [31].…”

Investigation of hydrodynamic interaction between the vessel and the seabed when entering shallow water is considered one of the most critical considerations of inland waterway transport. There are many investigations into the behavior of ships in restricted waters, such as ships traveling in different forms of canal cross-sections. The present study aims to evaluate the hydrodynamic interaction of the 750 DWT Perintis Ship moving through the different canal types to determine the relative effects of limiting the width and depth cross section on the ship's resistance. Two different canals with different cross sections, including canal bank and rectangular canal, were evaluated to investigate the influence of canal width (Wb), depth ratio (hw/T), and blockage ratio function (As/Ac). The Computational Fluid Dynamic (CFD) method with Reynolds-averaged Navier–Stokes (RANS) solver and turbulent model 𝑘−𝜀 were used to predict the total resistance of the ship. The proposed numerical simulation was initially validated with an experimental towing tank test in the error range of 0.11-7.74%. The results indicated similar phenomena were found both in rectangular and canal banks. The case with a shallower (lower hw/T) and a narrower (lower Bc/Bs) canal dimension has a higher resistance value. Backflow and subsidence of free surface became significant around the ship's hull in more restricted water, changing the ship's hydrodynamic characteristics and increasing resistance. It can be found that the higher the blockage ratio (mb), the higher the total resistance value in both canal types, which proved that ships with higher speeds were more sensitive to changes in waterway restrictions.

“…Near critical speed, a large increase in resistance and sinkage was observed. Lahbib Zentari et al [9] studied the resistance and propulsion performance of coupled pusher-barge convoys in shallow water through ship model experiment and numerical simulation, then analysed the effect of shallow water on the resistance and propulsion of the ship. The results of the ship model experiments are relatively reliable, but the experiment time and economic costs were high.…”
