What is it about?

The fluid flow in the universe is primarily turbulent. From the flow in the pipe, river, blood in veins, spreading of the viruses, multi-flow mixing, combustion, convection, diffusion, and wind flow around the airplane, Turbuemachines flow to Solar flares, some planets made of gas, and coronal flux, all are turbulent phenomena. It is an unsolved problem in physics, as Richard Feynman said. Besides the complexity of the turbulent flow, the fluid flow is composed of particles and fluid, broadly seen in natural and artificial cases. Moreover, gravity is another effective item on the particles moving in the fluid flow. Studying and knowing much more practically is crucial to discover this phenomenon. This study designed a novel empirical method to simulate a deformed turbulent flow in the presence of gravity and presents insight to investigate the behavior of the particles in such flow, which is widely applicable.
