Fluid dynamics investigates the motion of fluids, a realm characterized by two fundamental states: steady motion and turbulence. Steady motion refers to a fluid flow where velocity at any given point remains constant over time. In contrast, turbulence emerges when fluid motion becomes chaotic and unpredictable, characterized by fluctuating velociti
