摘要

Abstract

The second-order moment combustion model

proposed by the authors is validated using the direct numerical simulation(DNS)of incompressible turbulent reacting channel flows.The instantaneous DNS results show the near-wall strip structures of concentration and temperature fluctuations.The DNS statistical results give the budget of the terms in the correlation equations

showing that the production and dissipation terms are most important.The DNS statistical data are used to validate the closure model in RANS second-order moment(SOM) combustion model.It is found that the simulated diffusion and production terms are in agreement with the DNS data in most flow regions

except in the near-wall region

where the near-wall modification should be made

and the closure model for the dissipation term needs further improvement.The algebraic second-order moment(ASOM) combustion model is well validated by DNS.
