본 연구에서는 미세격자구역에서 속도에 관한 모든 운송방정식(transport equation)과 압력방정식을 푸는 완전미세격자법을 채택하였고 거친 격자구역에서는 K,
The paper describes the incorporation of an algebraic stress model(ASM) of turbulence in to a semi-elliptic solution procedure for the prediction of turbulent flow in passage around a 180.deg. square sectioned bend. The numerical results are obtained from a finite-volume discretization with applications of QUICK scheme and full find grid system without PSL approximation. Results show that the better agreements in velocity profiles with experimental data than those from k,
