Predicting ship resistance in shallow water conditions is very important for the operational considerations of a ship. Shallow waters greatly affect viscous resistance, wave and also propulsion efficiency. This study aims to determine effect depth on ferry. The CFD method was used simulate this phenomenon its effects hull starting from coefficient surge force, sway force yaw (hydrodynamic momen...

The powering requirement of a land yacht is one of the most important aspects of its design. In this respect the wind tunnel testing is an effective design tool. In fact, changing the parameters of the vehicle and testing the changes in the wind tunnel will give us a better understanding of the most efficient vehicle, and yet it is time consuming, expensive, and has inherent scaling errors. Ano...
