A spatially accelerating turbulent flow with longitudinally contracting walls

Analysis of Flow of Nanofluid through a Porous Channel with Expanding or Contracting Walls using Chebychev Spectral Collocation Method

In this work, we applied Chebychev spectral collocation method to analyze the unsteady two-dimensional flow of nanofluid in a porous channel through expanding or contracting walls with large injection or suction. The solutions are used to study the effects of various parameters on the flow of the nanofluid in the porous channel. From the analysis, It was established that increase in expansion r...

Asymmetric Flow of a Nanofluid between Expanding or Contracting Permeable Walls with Thermal Radiation

In the present study, the flow and heat transfer characteristics of a nanofluid in an expanding or contracting porous channel with different permeabilities in presence of thermal radiation are investigated. Analytical solutions for the flow variables are obtained by employing homotopy analysis method (HAM). Maxwell-Garnetts and Brinkman models are considered to calculate the thermal conductivit...

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Two-dimensional viscous flow between slowly expanding or contracting walls with weak permeability.

Since the transport of biological fluids through contracting or expanding vessels is characterized by low seepage Reynolds numbers, the current study focuses on the viscous flow driven by small wall contractions and expansions of two weakly permeable walls. The scope is limited to two-dimensional symmetrical solutions inside a simulated channel with moving porous walls. In seeking an exact solu...

Two-dimensional Viscous Flow through Permeable Walls with Expanding or Contracting Gaps

Abstract: In this study, the problem of laminar, isothermal, incompressible and viscous flow in a rectangular domain bounded by two moving porous walls, which enable the fluid to enter or exit during successive expansions or contractions, is solved using a series of based analytical techniques named Homotopy Perturbation Method (HPM), Differential Transformation Method (DTM) and Optimal Homotop...
