In this paper, a new method named Virtual Flux Method which allows calculations about flows around arbitrarily body shapes on Cartesian grid is proposed. To evaluate the validation of this new method, flows around a cylinder and a pair of cylinders were calculated and quantitative comparisons between Virtual Flux Method, Virtual Boundary Method and conventional body fitted coordinate method have been done. As a result, accuracy of the Virtual Flux Method is better than that of the Virtual Boundary Method, and is similar with that of the body fitted coordinate method. Also the Virtual Flux Method requires number of time steps for convergence of steady flows less than the Virtual Boundary Method does.
