# Sensitivity study on Monte Carlo solution procedure of two-phase turbulent flow

## Abstract

A parametrical sensitivity study on the stochastic separated flow model which adopts the Lagrangian framework with the Monte Carlo method to track the drops in turbulent flow field is performed. It is found that an approximate 10-[mu]m uniform width of each discrete size interval can adequately represent the spectral effects of drop size distribution in the investigated hollow-cone spray. The number of computational drops required for the statistically stationary solution is greatly dependent on the interval range of PDF domain employed. For the case using the interval range of PDF domain bounded within [+-] 1.5[radical]u[prime][sub i][sup 2], it is shown that the use of no less than 1,000 computational drops for each representative size can yield nearly invariant solution.
