    • Abstract
  • This paper is intended to evaluate the wall effects in the super-cavity flow past a test model held in a closed water tunnel, and to establish a theoretical correction rule. Based on the principle of independence of cavity expansion, mainly considering the longitudinal pressure gradient in the working section, a theoretical solution of the super-cavity shape in the closed water tunnel is derived. With the theoretical solution the wall effects are discussed, and a correction rule of the cavitation number is presented.
