Delay of Leidenfrost point during drop impact of surfactant solutions
Gudlavalleti V V S Vara Prasad, Purbarun Dhar, Devranjan Samanta
In this article, a novel method of increasing the dynamic Leidenfrost temperature is proposed through the addition of both anionic (SDS) and cationic (CTAB) surfactants to water dr…
Magnetoelastic effect in impact dynamics of nonNewtonian ferrofluid droplets
Gudlavalleti V V S Vara Prasad, Purbarun Dhar, Devranjan Samanta
In this article, we propose, with the aid of detailed experiments and scaling analysis, the existence of magneto-elastic effects in the impact hydrodynamics of non-Newtonian ferrof…
Thermal Response of Dielectric Nanoparticle Infused Tissue Phantoms during Microwave Assisted Hyperthermia
Dhiraj Kumar, Purbarun Dhar, Anup Paul
Hyperthermia has been in use for many years; as a potential alternative modality for cancer treatment. In this paper, an experimental investigation of microwave assisted thermal he…
Advection kinetics induced self assembly of colloidal nanoflakes into microscale floral structures
Purbarun Dhar
This article explores the governing role of the internal hydrodynamics and advective transport within sessile colloidal droplets on the self assembly of nanostructures to form flor…
Surface declination governed asymmetric sessile droplet evaporation
Purbarun Dhar, Raghavendra Kumar Dwivedi, A R Harikrishnan
The article reports droplet evaporation kinetics on inclined substrates. Comprehensive experimental and theoretical analyses of the droplet evaporation behaviour for different subs…
Control and modulation of droplet vaporization rates via competing ferro- and electro-hydrodynamics
Purbarun Dhar, Vivek Jaiswal, Hanumant Chate +1
Modification and control over the vaporization kinetics of microfluidic droplets may have strong utilitarian implications in several scientific and technological applications. The…
