“…This relation had been respected implicitly in LRR, FLT models [14,15] and explicitly in IP model [16], but violated by some other later models [8,17,18]. Since the pressure-strain rate correlation acts to restore turbulence isotropy, we consider Eq.…”

This article investigates the performance of second-moment closures in a rotating reference flame and presents a new closure for the rapid pressure-strain rate correlation based on the recently developed materially flame indifference principle. It is observed here that the existing second-moment closures with appropriate near-wall treatment can adequately predict flows in a rotating channel and in an axially rotating pipe for moderate rotation rate. Analysis of the newly proposed model indicates that it is capable of reflecting flow features under strong rotation.
