| Abstract: | A numerical study of flow of power law fluid in an elbow bend has been carried out. The motivation behind this study is to analyze the velocity profiles, especially the pattern of the secondary flow of power law fluid in a bend as there are several important technological applications to which such a problem has relevance. This problem especially finds applications in the polymer processing industries and food industries where the fluid needs to be pumped through bent pipes. Hence, it is very important to study the secondary flow to determine the amount of power required to pump the fluid. This problem also finds application in heat exchangers. The elbow geometry has been modeled using the software GAMBIT and then the geometry has been imported into FLUENT to carry out the numerical analysis. The problem has been dealt with for both shear thickening and shear thinning fluids. The results have been discussed for different values of power law index, n=0.6, 0.75, 0.9, 1.0, 1.35, 1.45, 1.55 and Re=200, 1100 and aspect ratio, N=0.7, 1.0, 5.0. A total of 42 cases have been simulated. |
