Computer programs for calculating partially cavitating blunt trailing edged cascade flows in nonlinear theory

In addition to the previously developed partially cavitating cascade theory, two new flow models were constructed in search of a better flow model for determining accurate force coefficients. Effort has been made for obtaining (1) physically acceptable flows, particularly the location of cavity boundary and (2) smooth matching of the flow characteristics between the partially cavitating and super-cavitating flow regimes. Based on the numerical results made with these flow models for practical blade profiles taken after a supercavitating propeller, it was found that no single flow model developed could handle the complete set of cascade geometries and incidence angles. One theory was supplemental to the other and no definite guideline was discovered for selection of an appropriate flow model for a specified flow condition to be solved except for a few weak evidences. This report is a users' manual for the computer programs developed above, describing the structure of program, input data set-up, typical output data and listing.
