직각분지관의 3차원 층류유동 수치해석 = Numerical Investigations of Three-Dimensional Incompressible Laminar Flows in a 90-Degree T-Branch

다국어 초록 (Multilingual Abstract)

Numerical investigations of three-dimensional laminar flows in a 90-degree T-branch of square cross-section were carried out. The incompressible Navier-Stokes equations in generalized curvilinear coordinates, using a pseudocompressibility approach for continuity equation, were solved by the implicit, approximately factored scheme of Beam and Warming in the framework of multi-block grids. Computation of a twodimensional bifurcation flow was in excellent agreement with experimental measurements available in the literature for stream wise velocity profiles in the main duct. Then, effects of branch to main flow rate ratios and inlet Reynolds numbers on the main duct flowfields were studied in the laminar range. The computed results revealed significant influence of the branch flow rate ratio on the flow characteristics of T-branch.
