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.
