Numerical simulation of spinning body spraying

In a recently published article, scientists discussed the internal swirling of metal beverage cans.
main application of this work is to simulate the rotary coating inside a two-piece metal beverage can.
the researchers deduced the lubrication form of the fluid mechanics equation and controlled the motion of the thin liquid film on the symmetrical substrate of any curved rotating axis

. The resulting equations are discrete and then numerically solved using an effective implicit finite differential algorithm. Non-Newtonian effects are included by combining Ellis viscosity models.
to eliminate possible defects in the rotary coating process
the main application of this work is to simulate the rotary coating inside two-piece metal beverage cans, which scientists have considered to some extent. Specifically, they show how several parameters can be adjusted to eliminate one possible defect in the rotational coating process: the tendency of droplets to disengage from the substrate when the tank rotates at a high rotational speed.
