Eulereuler anisotropic gaussian mesoscale simulation of homogeneous clusterinduced gasparticle turbulence
An Euler–Euler anisotropic Gaussian approach (EEAG) for simulating gas–particle flows, in which particle velocities are assumed to follow a multivariate anisotropic Gaussian distribution, is used to perform mesoscale simulations of homogeneous clusterinduced turbulence (CIT). A threedimensional Gauss–Hermite quadrature formulation is used to calculate the kinetic flux for 10 velocity moments in a finitevolume framework. The particlephase volumefraction and momentum equations are coupled with the Eulerian solver for the gas phase. This approach is implemented in an opensource CFD package, OpenFOAM, and detailed simulation results are compared with previous Euler–Lagrange simulations in a domain size study of CIT. Here, these results demonstrate that the proposed EEAG methodology is able to produce comparable results to EL simulations, and this momentbased methodology can be used to perform accurate mesoscale simulations of dilute gas–particle flows.
