Theory and simulation of elastoinertial rectification of oscillatory flows in two-dimensional deformable rectangular channels
Uday M. Rade, Shrihari D. Pande, Ivan C. Christov
Oscillatory flows in compliant confinements underpin processes ranging from physiological transport in blood vessels and airways to flow control and pumping in soft microfluidic de…
A fluid--peridynamic structure model of deformation and damage of microchannels
Ziyu Wang, Ivan C. Christov
Soft-walled microchannels arise in many applications, ranging from organ-on-a-chip platforms to soft-robotic actuators. However, despite extensive research on their static and dyna…
Oscillatory flows in three-dimensional deformable microchannels
Anxu Huang, Shrihari D. Pande, Jie Feng +1
Deformable microchannels emulate a key characteristic of soft biological systems and flexible engineering devices: the flow-induced deformation of the conduit due to slow viscous f…
Experimental investigation of the flow rate--pressure drop relation of a viscoelastic Boger fluid in a deformable channel
SungGyu Chun, Ivan C. Christov, Jie Feng
We study the steady flow-induced deformation between an incompressible non-Newtonian fluid and a three-dimensional (3D) deformable channel. Specifically, we provide a comprehensive…
Asymptotic Behavior of a Buoyant Jet Regime inside a Carbon-dioxide Ejector
Sreetam Bhaduri, Ivan C. Christov, Eckhard A. Groll +1
Ejectors are used in various engineering systems, including steam and vapor compression cycles. Optimizing the performance of ejectors requires understanding and analysis of multip…
Non-self-adjoint sixth-order eigenvalue problems arising from clamped elastic thin films on closed domains
N C Papanicolaou, I C Christov
Sixth-order boundary value problems (BVPs) arise in thin-film flows with a surface that has elastic bending resistance. We consider the case in which the elastic interface is clamp…
