Abstract

論文(Article)

This paper presents the numerical simulation of unstable flow along the surface of a circular cylinder in the Coanda effect. The unstable phenomenon is governed by a nominal Reynolds number Re^*= U_j√ and the nozzle height of the jet, h. In this paper, the changing phenomenon of two-dimensional jet direction is found numerically and is compared with the experimental results. The numerical calculation was carried out by using the finite-difference method for the conditions of unstable phenomenon, that is, 1.0X10^4
