Time averaged modeling of BFBs: Analysis of the terms in the momentum equations

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review

    Abstract

    Steady state CFD simulation would present an attractive alternative for the computationally demanding transient simulations in the case of large, industrial scale BFBs. In the present paper, the features and relative importance of the various terms appearing in steady state flow equations are analyzed based on a transient simulation. According to this analysis, the most important terms in the momentum equations are the gas-solid drag term and the solid volume fraction and gas pressure fluctuation correlation terms. The solid pressure and the Reynolds stress terms are also found to be important.
