The fin­ish of radio fre­quency (RF) sur­faces in­side su­per­con­duct­ing RF (SRF) cav­i­ties is of ut­most im­por­tance as it dic­tates ul­ti­mate cav­ity per­for­mance. After the cav­ity sur­faces have un­der­gone chem­i­cal etch­ing, pol­ish­ing, and hy­dro­gen de­gassing, the final step in sur­face prepa­ra­tion in­volves clean­ing using a high pres­sure rinse (HPR) with ul­tra-high pu­rity water (UPW) to re­move any residue from the pre­vi­ous chem­i­cal processes. The com­plex sur­face geom­e­try of cav­i­ties poses dif­fi­cul­ties in achiev­ing ef­fec­tive and thor­ough HPR clean­ing. This study in­tro­duces a ver­sa­tile sim­u­la­tion tool cre­ated in MAT­LAB, which has the po­ten­tial to be ap­plied to var­i­ous SRF cav­i­ties. The de­tail of the al­go­rithm used and noz­zle and mo­tion setup will be de­scribed using an FRIB 0.53 half wave res­onator (HWR) cav­ity as an ex­am­ple.
