Present paper treats the cavity flows of elastic symmetrical wedge by singularity method and clarifies the notable inter-relationships of cavity flow models to beam stiffness on cavity characteristics. The main results are summarized as follows; (1) While using the analytic relations for the cavity length and cavitation coefficient, the beam deflection is determined by iteration procedures from bending equation and then the cavity characteristics such as the pressure difference between the in-and out-sides of wedge, the cavity length and also the cavity drag are finally obtained. (2) As an typical example for exter-and inter-nal flows, the cavity flows in gravity field and passage between parallel walls are examined respectively: Some notable relationships of beam stiffness to cavity flow models, in particular the reduction of cavity drag by beam deflection are pointed out concreately through some numerical examples for each cases.
