In this paper the Fourier transform combined with Adomian decomposition method (FTADM) is applied for solving the squeezed unsteady flow between parallel plates influenced by an inclined magnetic field. By moving these plates toward each other, the squeezing flow which is perpendicular to the plates is appeared. We…

'S. Suresh Kumar Raju' 'Chakravarthula S. K. Raju' 'Macherla JayachandraBabu' 'Raad Z. Homod' 'Wael Al-Kouz' 'Taseer Muhammad' 'Metib Alghamdi'] Squeezing flow is a flow where the material is squeezed out or disfigured within two parallel plates. Such flow is beneficial in various fields, for instance, in welding…

This article explores the influence of Joule heating and viscous dissipation on the unsteady three-dimensional squeezing flow of Newtonian fluid. The flow in a rotating channel with a lower stretched permeable wall is observed under the influence of a uniform magnetic field. The impact of thermal radiation is also…

'Emin Bayraktar' 'Giorgio Luciano' 'Paola Stagnaro' 'Maurizio Vignolo'] In the process of rubber extrusion, the feed structure directly affects the extrusion quality, extrusion uniformity, screw lateral force, and feed power consumption. Until now, the feed structure was mainly based on empirical designs, and there was…

This work has explored interface evolution and pinch-off mechanism of the droplet formation in two-phase flow through cross-flow microfluidic device. The two-dimensional mathematical model equations have been solved using the finite element method under the squeezing regime (Cac < 10−2 ) for wide range of flow rates…

'Ahmed M. Galal'] The ongoing research aims to examine the mass and heat transmission phenomena of squeezing flow between two concentric cylinders under the effect of heat sources and magnetic fields. The impacts of the Lorentz force on the behavior of the liquid flow are elucidated via a magnetic field incorporated in…

'Yannis Dimakopoulos'] This paper studied the evolution of NaAlg solution micro-droplet in a coaxial microchannel. The Bird-Carreau model was used to characterize the flow properties of NaAlg solution. As the mass fraction decreased, the flow behavior index n also decreased, indicating that the NaAlg solution was…

We study numerically how multiple deformable capsules squeeze into a constriction. This situation is largely encountered in microfluidic chips designed to manipulate living cells, which are soft entities. We use fully three-dimensional simulations based on the lattice Boltzmann method to compute the flow of the…

Exchange of molecules between cerebrospinal fluid (CSF) and brain cells contributes to brain function and protection from dementia, but the route by which CSF is brought close enough to the neural tissue to be exchanged by extracellular diffusion is not clear. Exogenous molecules injected into CSF are carried along…

We explore the squeezed back-to-back correlation (SBBC) and investigate how the squeezing effect influences the Hanbury Brown-Twiss (HBT) interferometry using an expanding Gaussian source with non-zero width. The SBBC and HBT of D 0 and φ mesons with finite in-medium widths are studied. The expanding flow of the source…

We have developed a coupled level set and volume of fluid (CLSVOF) based computational fluid dynamics (CFD) model to analyze the droplet formation mechanism in a square flow–focusing microchannel. We demonstrate a flexible manipulation of droplet formation and flow regime based on the modified flow–focusing…

Cancer cells can utilize different invasion strategies to overcome physical arrest during confined migration through tissues with small pores. Cancer cell plasticity allows switches between different migration modes and transitions between single-cell and collective migration. The biophysical parameters that guide…

Mammalian cell culture in nanoliter droplets of extracellular matrix has recently attracted interest as a platform for high throughput drug screening on 3D tissue models. Microfluidic droplet generation using basement membrane extract, such as Matrigel or Cultrex, is complicated by the fact that the viscosity is orders…

'L. Mahadevan'] Soft valves serve to modulate and rectify flows in complex vasculatures across the tree of life, e.g. in the heart of every human reading this. Here we consider a minimal physical model of the heart mitral valve modeled as a flexible conical shell capable of flow rectification via collapse and…

Polymer flows through pores, nozzles and other small channels govern engineered and naturally occurring dynamics in many processes, from 3D printing to oil recovery in the earth's subsurface to a wide variety of biological flows. The crosslinking of polymers can change their material properties dramatically, and it is…

In suspension flows through microchannels with parallel walls, rigid particles form clogs that grow continuously in the upstream direction. However, introducing a slight taper to channel walls leads to a qualitatively different clogging mechanism. Clogs of rigid particles do not grow continuously in these tapered…

Controlled fluid flows are the hallmark feature of microfluidic culture systems and provide precise definition over the biophysical and biochemical microenvironment. Flow control is commonly achieved using displacement-based (e.g., syringe or peristaltic pumps) or pressure-based techniques. These methods offer complex…

Reliable extrusion of viscoelastic hydrogels is crucial for technologies ranging from 3D (bio)printing to injectable therapeutics, yet current methods to characterize extrusion performance fail to mimic key processing conditions. Consequently, extrusion performance cannot be precisely predicted or controlled…

Fluid flow is an inherent aspect of solution processing of conjugated polymers. Much of the existing work investigating the effect of flow has been phenomenological, lacking a direct and quantitative connection between the flow gradients and measurable quantities of the conformation or alignment of the conjugated…

Immersed nonlinear elements are prevalent in biological systems that require a preferential flow direction. A certain class of models is investigated where the fluid is driven by peristaltic pumping and the nonlinear elements are ideal valves that completely suppress backflow. This highly nonlinear system produces…
