Abstract: | The computational study of non-Newtonian fluid such as paint past a solid hurdle in channel flow is substantial to many manufacturing problems related with industries. Numerous techniques such as analytical and numerical simulation can be used to study such fluid flow. In the current study shear thinning viscoelastic fluid is taken into consideration. 2-D study is under investigation in the current study using Oldroyld-B model. In the contemporary study the core focus is emphasized on flow of Non-Newtonian fluid past different shapes of solid obstacles, such as triangle and trapezium. Structured meshes are used to investigate the accuracy, stability and consistency of the numerical scheme for both types of obstacles. The parabolic behaviour of the flow verifies stability and consistency of the scheme. Finite element Semi implicit time-stepping Taylor/ Galerkin Pressure Correction Scheme is employed for the simulation. The main focus of the study is to analyse the flow pattern of the fluids while crossing solid hurdles because of its importance in mixing and beading process of materials. |
