Numerical Analysis of Branch Flows for Newtonian and Non-Newtonian Fluids

뉴턴유체와 비뉴턴유체에 대한 분기관 유동의 수치해석

Branch flows for Newtonian and non-Newtonian fluids are simulated by the finite volume method. The modified power-law model is employed as a constitutive equation of the non-Newtonian fluids. Numerical analyses are focused on understanding of flow patterns for different values of branch angles, diameter ratios and Reynolds numbers. The numerical results are compared with the existing experimental data. The calculated velocity profiles and pressure variations are in good agreement with available experimental results.
