| সারসংক্ষেপ≠ | Seakeeping strip theory is a method for predicting the dynamic motion of a ship in regular and irregular waves by decomposing the hull into two-dimensional transverse sections (strips) and computing the hydrodynamic forces on each strip. Developed by Salvesen, Tuck, and Faltinsen in 1970, the method efficiently estimates ship heave, pitch, and roll motions, accelerations, and loads without resorting to expensive three-dimensional computational fluid dynamics. Seakeeping analysis using strip theory is standard in ship design and operational planning. | Propeller lifting line theory is a mathematical framework for analyzing and designing ship propellers by modeling each blade as a lifting line with circulation distribution. Developed by Sydney Goldstein in 1929 and refined by Kerwin and others, the method accounts for blade loading, wake effects, and propeller interactions. Lifting line theory provides efficient predictions of propeller thrust, torque, and efficiency and remains standard in preliminary propeller design and optimization. |
