Derivation of drag and lift force and torque coefficients for non-spherical particles in flows

► We use DNS to model the flow around four types of non-spherical particles. ► The results are compared to literature correlations. ► New models are proposed for drag, lift and the two torques for the particles. ► The models fit very well with the simulation results. ► These models can be used in large-scale gas-solid computations.
