Numerical study on hydrodynamic resistance of new hull design for multipurpose amphibious vehicle

Multipurpose Amphibious Vehicles (MAV) and other blunt-shaped floating vehicles encounter the problem of a large bow wave forming at high speeds. This wave formation is accompanied by higher resistance and at a critical speed results in bow submergence or swamping. Three new shapes of hull bow desig...
