whirlpool, eddy, vortex
渦 centers on a spiraling flow of water: a whirlpool, eddy, or vortex. All meanings describe the same circular, pulling motion in fluid.
渦 combines 氵 (water) with 咼, which likely contributes the sound and the idea of a hollow or spiral shape, together suggesting a whirlpool.
Water 氵 swirls around a hollow spiral shape 咼, forming a whirlpool that pulls everything into its center.
For カ, imagine a whirlpool spinning like a car tire stuck in mud: car -> カ, and the water circles endlessly.
