Abstract:
A method of using a processor to receive signals from an input device providing an object shape by performing operations for determining the object shape that minimizes aerodynamic noise generated upon movement of the object through a fluid medium, comprising:a first step of setting an initial object shape;a second step of generating a numerical fluid dynamic grid on a surface of the object shape;a third step of numerically solving, by numerical fluid dynamics, Navier-Stokes equations based on the grid generated with the object shape and the object, and determining a pressure of the object surface;a fourth step of determining noise generated by said object by solving Curle's formula based on the pressure of the object surface; anda fifth step of updating the object shape while repeating said first through fourth steps and determining the noise thereof,wherein the shape of said object is determined based on a shape which generates the smallest noise from among the noises determined in said fifth step.
