Etymology
沸 combines 氵 (water) with 弗, which likely contributes the sound and the idea of something being forcefully expelled or rising, as in boiling water.
Meaning mnemonic
Water 氵 beside 弗, which looks like a bow with arrows, suggests water shooting up like arrows when it boils.
Reading mnemonic
For フツ, imagine a pot of water boiling so fiercely it makes a 'futs futs' sound: futs -> フツ.
