It is presented through numerical analysis that accelerated motions of a two-dimensional fish-like foil by fluid forces can be modeled from impulsive starts to terminal states. Time histories of drag coefficient and foil speed depend on a frequency and motion of a foil and amplitude of its caudal fin. Three models that take thrust. inertial drag and viscous drag into account for the t... https://storeanimalwiz.shop/product-category/in-line/
