“…The numerical simulation outcomes for fluctuating stream tariffs represented in The impacts of sluggishness are amplified with an improve in Re number, which can be envisioned by the progress in size, separating, and blending of eddies within significant area of the upper arm. In the smaller limb, unidirectional stream is restrained after the stream scale in the higher limb is adjusted from inadequate (1, 1.5) to equal (1,2). Taking apart and merging are mostly directed trendy the lower limb or in the mid space of the domain.…”

“…As previously mentioned, the discussion focuses solely on equal (1, 1) flow rates within this specific configuration of unidirectional flow, and the changes in pressure difference align with this setting. (1,2) in together rests of route structure. Numerical testing produced calculations at a Re number of 1 and a thickness limitation (W) of 0.17, Conversely, the experimental outcomes were achieved at a Reynolds number (Re) of 0.75 and thickness limit (W) of 0.17.…”

Fluid flows in channel systems are prevalent in many industrial and engineering applications. Flow rates, Reynolds numbers, and inertia significantly impact the dynamics of fluid flows in channel systems. However, analyzing these factors' effects on fluid flows is challenging. This study investigates the impact of flow rates, Reynolds numbers, and inertia on fluid flows within a channel system filled with non-porous media using Taylor-Galerkin/Pressure-Correction Scheme. Various flow conditions, including equal and unequal flow rates, reversed flow, and unidirectional flow, are analyzed to determine the effects on pressure differences and streamline patterns by numerical simulation. The results demonstrate the crucial role of inertia on vortex development, pressure differences, and the formation of eddies in different regions of the channel. The study reveals that pressure differences increase linearly with increasing Reynolds number in unidirectional flow scenarios and that unequal flow rates can significantly alter flow behavior. The study's findings provide insight into the complex interplay between flow rates, inertia, and pressure variations in fluid flows within a channel system.

In this research study the tank model of isothermal and unsteady drainage is considered. Geometry of the tank is in cylindrical and at the bottom a pipe for flow of the fluid is attached. Sub class of viscoelatic non-newtonian fluid is considered. It is planed to obtain the series solution of the model with Adomian Decompositon in the light of no slip conditon. It is also decided to compare the velocity profile of adomain decompositon with the perturbation method for this fluid. On the basis of the results and comparison efficiency of both methods will be disscussed.
