Wrinkling and multiplicity in the dynamics of deformable sheets in uniaxial extensional flow
Yijiang Yu, Michael D. Graham
The processing of thin-structured materials in a fluidic environment, from nearly inextensible but flexible graphene sheets to highly extensible polymer films, arises in many appli…
Constitutive modeling of dilute wormlike micelle solutions: shear-induced structure and transient dynamics
Richard J. Hommel, Michael D. Graham
We present a reformulation of the 'reactive rod model' (RRM) of Dutta and Graham [Dutta, Sarit and Graham, Michael D., JNNFM 251 (2018)], a constitutive model for describing the be…
Coil-stretch-like transition of elastic sheets in extensional flows
Yijiang Yu, Michael D. Graham
The conformation of a long linear polymer dissolved in fluid and exposed to an extensional flow is well-known to exhibit a "coil-stretch" transition, which for sufficiently long ch…
Margination regimes and drainage transition in confined multicomponent suspensions
R. G. Henríquez Rivera, K. Sinha, M. D. Graham
A mechanistic theory is developed to describe segregation in confined multicomponent suspensions such as blood. It incorporates the two key phenomena arising in these systems at lo…
Mechanism of margination in confined flows of blood and other multicomponent suspensions
Amit Kumar, Michael D. Graham
Flowing blood displays a phenomenon called margination, in which leukocytes and platelets are preferentially found near blood vessel walls, while erythrocytes are depleted from the…
Segregation by membrane rigidity in flowing binary suspensions of elastic capsules
Amit Kumar, Michael D. Graham
Spatial segregation in the wall normal direction is investigated in suspensions containing a binary mixture of Neo-Hookean capsules subjected to pressure driven flow in a planar sl…
Accelerated boundary integral method for multiphase flow in non-periodic geometries
Amit Kumar, Michael D. Graham
An accelerated boundary integral method for Stokes flow of a suspension of deformable particles is presented for an arbitrary domain and implemented for the important case of a pla…
Diffusion and spatial correlations in suspensions of swimming particles
Patrick T. Underhill, Juan P. Hernández-Ortiz, Michael D. Graham
Populations of swimming microorganisms produce fluid motions that lead to dramatically enhanced diffusion of tracer particles. Using simulations of suspensions of swimming particle…
Slip, concentration fluctuations and flow instability in sheared polymer solutions
William B. Black, Michael D. Graham
Recent experiments suggest that shear-enhanced growth of concentration fluctuations in polymer solutions is strongly influenced by solid boundaries. We analyze the dynamics of a mo…
