Comparative study of the virtual flux method and immersed boundary method coupled with regularized lattice Boltzmann method for suspension flow simulations

•RLBM coupled with three different schemes was examined in steady flow past a stationary cylinder.•VFM and IBB are economical computational time compared to IBM for stationary problems.•Relative viscosity by the VFM or IBM was comparable for dilute suspension (
