The simulations encompass resistance tests at various depths and velocities within the CFD environment. The impact of water depth reduction on frictional and pressure resistance components, as well as ship trimming and sinking, is assessed. A comprehensive analysis of changes in the wave pattern around the ship is conducted. Numerical results exhibit a substantial increase in resistance, trim, and sinkage with decreasing depth, highlighting the profound influence of shallow water conditions on the hydrodynamic behavior of the ship.</span></span></span><br> &nbsp; Shallow water,CFD,Wave pattern,Resistance test 57 64 http://ijmt.ir/browse.php?a_code=A-10-1100-2&slc_lang=en&sid=1 Hamidreza Mahmoodi h947012046@gmail.com 10031947532846004236 10031947532846004236 No Khorramshahr University of Marine Science and Technology Ahmad Hajivand hajivand@kmsu.ac.ir 10031947532846004237 10031947532846004237 Yes Khorramshahr University of Marine Science and Technology
