Numerical Simulation of Vortex-Induced Vibration With Bistable Springs : Consistency with the Equilibrium Constraint
Rameez Badhurshah, Rajneesh Bhardwaj, Amitabh Bhattacharya
We present results from 2-D numerical simulations based on Immersed Boundary Method of a cylinder in uniform fluid flow attached to bistable springs undergoing Vortex-Induced Vibra…
A finite-element model for computing fluid flow inside a sessile evaporating droplet on a solid surface
Manish Kumar, Rajneesh Bhardwaj
A finite element model was developed to compute the fluid flow inside a sessile evaporating droplet on hydrophilic substrate in ambient conditions. The evaporation is assumed as qu…
Computational Modeling and Analysis of Flow-induced Vibration of an Elastic Splitter Plate Using a Sharp-interface Immersed Boundary Method
Anup Kundu, Atul K. Soti, Hemanshul Garg +2
We present the development and benchmarking of an in-house fluid-structure interaction (FSI) solver. An implicit partitioned approach is utilized to couple a sharp-interface immers…
Interfacial temperature measurements, high-speed visualization and finite-element simulations of droplet impact and evaporation on a solid surface
Rajneesh Bhardwaj, Jon P. Longtin, Daniel Attinger
The objective of this work is to investigate the coupling of fluid dynamics, heat transfer and mass transfer during the impact and evaporation of droplets on a heated solid substra…
Self-assembly of colloidal particles from evaporating droplets: role of DLVO interactions and proposition of a phase diagram
Rajneesh Bhardwaj, Xiaohua Fang, Ponisseril Somasundaran +1
The shape of deposits obtained from drying drops containing colloidal particles matters for technologies such as inkjet printing, microelectronics and bioassay manufacturing. In th…
Pattern formation during the evaporation of a colloidal nanoliter drop: a numerical and experimental study
Rajneesh Bhardwaj, Xiaohua Fang, Daniel Attinger
An efficient way to precisely pattern particles on solid surfaces is to dispense and evaporate colloidal drops, as for bioassays. The dried deposits often exhibit complex structure…
