A new immersed boundary-lattice Boltzmann method (IB-LBM) is proposed.It is based on the newly developed lattice Boltzmann equation with external forcing term, which can well consider the effect of external force to the momentum and momentum flux as well as the discrete lattice effect.In this model, the velocity is contributed by two parts.One is from the density distribution function and can be termed as intermediate velocity, and the other is from the external force and can be considered as velocity correction.In the conventional IB-LBM, the force density (external force) is explicitly computed in advance.
