Diversion cross-flow is an unidirectional cross-flow in a non-equilibrium flow, and occurs due to the time-averaged pressure difference between the subchannels. In this paper, experiments and analysis of the diversion cross-flow between triangle tight lattice rod bundle subchannels are presented. In the experiment, flow rates of gas and liquid, the pressure difference between the subchannels and the void fraction in each subchannel were obtained. In the analysis, the flow rates of gas and liquid, the pressure difference and the void fraction were calculated with the present subchannel analysis code based on a two-fluid model. The calculated results agree reasonably well with the experimental results.
