Particle-Resolved Direct Numerical Simulations has been performed using Implicit Tensorial Viscous penalty method [1] with ellipsoidal particles to extract the drag and lift force excreted by the fluid on the particles and the Nusselt number of the particles. The simulations results are compared to existing correlations for a single ellipsoid by changing the incident angle at different Reynolds number (figure 1 right). A new Lagrange extrapolation coupled to a Taylor interpolation of high order [3] is used to calculate the drag, lift forces and the heat flux. This work is an extension to the one for a spherical particle [3].< Leer menos
