I would say the Flood would dominate the Tyranid since the meaning of the Flood's name means "Dead Reincarnated" and are notorious zombie-making parasites thanks to them assmimilating and consuming any biologically living organism on a molecular level. I don't know if its true if the Tyranids are still breathing monsters or extragalactic undead monstrosities but the Flood can possess and corrupt living and deceased victims and prey for their expanding purposes and like the Tyranids there's no stopping them in terms of continuously spreading all over the interstellar galaxy. But since the Flood start off as Infection Forms then larger Tyranids wouldn't stand a chance against them, heck Hunters of the Covenant can't stand a chance against them.

Heck think Necromorphs vs. Tyranids and the real winner would the Necromorphs since like the Flood can infect and assimilate victims that are dead (even though the Flood do infect still-living prey) and also "make zombies" out of corpses but they can expand their mass to the mostly extreme violent carnage levels as Necromorph-infected-Tyranids can do more damage of what the Tyranids can originally do.
