IOP Conference Series: Materials Science and Engineering, 2013 The internal flow of an annular jet pump is an annular wall jet developed in a limited space, which is affected by its structure, shape, area ratio and flow rate ratio. In this paper, numerical simulation of an annular jet pump with area ratio A=1.75 was conducted based on realizable k-e turbulence model.
