Abstract

A closure is developed for the time-averaged cross correlation between fluctuating conformation and rate of strain tensors appearing in the evolution equation of the conformation tensor for the polymer stress of the FENE-P fluid. The closure was calibrated against DNS data pertaining to the low and high drag reduction regimes.
