Brachistochronous motion of a flat plate parallel to its surface immersed in a fluid
S. Mandre
We determine the globally minimum time needed to translate a thin submerged flat plate a given distance parallel to its surface within a work budget. The Reynolds number for th…
How to run on rough terrains
Nihav Dhawale, Shreyas Mandre, Madhusudhan Venkadesan
Stability of running on rough terrain depends on the propagation of perturbations due to the ground. We consider stability within the sagittal plane and model the dynamics of runni…
Surface tension of flowing soap films
Aakash Sane, Shreyas Mandre, Ildoo Kim
The surface tension of flowing soap films is measured with respect to the film thickness and the concentration of soap solution. We perform this measurement by measuring the curvat…
Transverse contributions to the longitudinal stiffness of the human foot
Ali Yawar, Lucia Korpas, Shreyas Mandre +1
Humans rely on foot stiffness to withstand the propulsive forces of walking and running. Skeletal adaptations that increase foot stiffness include the medial longitudinal arch (MLA…
Stiffness of the human foot and evolution of the transverse arch
Madhusudhan Venkadesan, Marcelo A. Dias, Dhiraj K. Singh +2
Foot stiffness underlies its mechanical function, and is central to the evolution of human bipedal locomotion. The stiff and propulsive human foot has two distinct arches, the long…
Hydrodynamic signatures of stationary Marangoni-driven surfactant transport
S. Mandre, V. S. Akella, D. K. Singh +2
We experimentally study steady Marangoni-driven surfactant transport on the interface of a deep water layer. Using hydrodynamic measurements, and without using any knowledge of the…
Axisymmetric spreading of surfactant from a point source
S. Mandre
Guided by computation, we theoretically calculate the steady flow driven by Marangoni stress due to surfactant introduced on a fluid interface at a constant rate. Two separate extr…
Dynamics of a Camphoric Acid boat at the air-water interface
V. S. Akella, D. K. Singh, S. Mandre +1
We report experiments on an agarose gel tablet loaded with camphoric acid (c-boat) set into self-motion by interfacial tension gradients at the air-water interface. We observe thre…
Marangoni elasticity of flowing soap films
Ildoo Kim, Shreyas Mandre
We measure the Marangoni elasticity of a flowing soap film to be 22 dyne/cm irrespective of its width, thickness, flow speed, or the bulk soap concentration. We perform this measur…
Curvature-induced stiffening of a fish fin
Khoi Nguyen, Ning Yu, Mahesh M. Bandi +2
How fish modulate their fin stiffness during locomotive manoeuvres remains unknown. We show that changing the fin's curvature modulates its stiffness. Modelling the fin as bendable…
Framework for systematic flow manipulation by wind and hydrokinetic energy turbine arrays
Shreyas Mandre, Niall M. Mangan
Wind and hydrokinetic energy turbines are often constrained to locations where the available energy is limited by the operation of the turbines themselves. In two-dimensions, we de…
Elastohydrodynamics of contact in adherent sheets
Andreas Carlson, Shreyas Mandre, L. Mahadevan
Adhesive contact between a thin elastic sheet and a substrate in a liquid environment arises in a range of biological, physical and technological applications. By considering the d…
Dynamics of evaporative colloidal patterning
C. Nadir Kaplan, Ning Wu, Shreyas Mandre +2
Drying suspensions often leave behind complex patterns of particulates, as might be seen in the coffee stains on a table. Here we consider the dynamics of periodic band or uniform…
Monami as an oscillatory hydrodynamic instability in a submerged sea grass bed
Ravi Singh, M. M. Bandi, Amala Mahadevan +1
The onset of monami ~-- the synchronous waving of sea grass beds driven by a steady flow -- is modeled as a linear instability of the flow. Unlike previous works, our model conside…
Skating on a Film of Air: Drops Impacting on a Surface
John M. Kolinski, Shmuel M. Rubinstein, Shreyas Mandre +3
Drops impacting on a surface are ubiquitous in our everyday experience. This impact is understood within a commonly accepted hydrodynamic picture: it is initiated by a rapid shock…
Algorithm for a microfluidic assembly line
Tobias M. Schneider, Shreyas Mandre, Michael P. Brenner
Microfluidic technology has revolutionized the control of flows at small scales giving rise to new possibilities for assembling complex structures on the microscale. We analyze dif…
