Immersed Boundary-Finite Difference Lattice Boltzmann Method Using Two Relaxation Times

Immersed Boundary-Finite Difference Lattice Boltzmann Method Using Two Relaxation Times

Immersed boundary-lattice Boltzmann methods (IB-LBM) with the single-relaxation time (SRT) cause non-physical distortion in fluid velocity when the Reynolds number is low, i.e. the relaxation time τ is high, and IB-LBM requires high spatial resolution to stably simulate high Reynolds number...
