반구형 전두부 실린더에서 발생하는 캐비테이션 유동의 압축성 효과에 대한 수치해석 연구 = NUMERICAL ANALYSIS OF CAVITATION WITH COMPRESSIBILITY EFFECTS AROUND HEMISPHERICAL HEAD-FORM BODY

다국어 초록 (Multilingual Abstract)

Cavitation on an axi-symmetric hemispherical head-form body was studied using an Reynolds-averaged Navier-Stokes equations solver based on a cell-centered finite volume method. To consider compressibility effects on the vapor phase and cavity interface, a pressure-based compressible flow CFD code was developed. To validate the developed CFD code, cavitating flow around the hemispherical head-form body was simulated using pressure-based incompressible and compressible CFD codes and validated against existing experimental data in the three-way comparison. The cavity shedding behavior, length of re-entrant jet, drag history, and Strouhal number of the hemispherical head-form body were compared between two CFD codes. The results, in this paper, suggested that the computations of cavitating flow with compressibility effects improve the description of cavity dynamics.
