Özet
Squids in nature generate pulsed jet to be able to move by expelling high pressure water through funnel in a short period of time. In this study, unsteady jet flow of squids was investigated during its fast swimming phase. Numerical model has been generated from a real squid's computer tomography images. 2D axisymmetric jet flow has been simulated by using dynamic mesh to mimic the motion of squid's mantle cavity wall. Specifically, diameter of the squid's mantle cavity decreases from 13 cm to 4 cm and a periodic sine velocity profile has been defined for squid's mantle cavity wall. Besides, the funnel of squid seems to be a 3 cm long nozzle which has about 3 cm and 0.5 cm diameters at the inlet and outlet, respectively. Physical behaviors of jet flow has been investigated to be able to calculate change of ejected fluid's momentum and flow energy in this study
Abstract
