Experimental hydrodynamics of turning maneuvers in koi carps
Experimental hydrodynamics of two types of turning maneuvers in koi carps (cyprinus carpio koi) are studied. The ow patterns generated by koi carps during turning are quantified by using digital particle image velocimetry. Based on the velocity fields measured, the momentums in the wake and the impulsive moments exerted on the carps are estimated. On the other hand, turning rates and radii, and moments of inertia of the carps including added mass during turning are obtained by processing the images recorded. Comparisons of the impulsive moments and moments of inertia show good agreements.
