Analysis of Hematocrit-Plasma Separation in a Trifurcated Microchannel by a Diffusive Flux Model
Rishi Kumar, Indranil Saha Dalal, K. Muralidhar
Platelet-enriched plasma and red blood cells (RBC) are needed in the treatment of blood-related diseases, including anaemia and blood cancer. These essential components must be sep…
Automatic Estimation of Pedestrian Gait Features using a single camera recording: Algorithm and Statistical Analysis for Gender Difference and Obstacle Interactions
Kanika Jain, Abhishek Gupta, Indranil Saha Dalal +2
The pedestrian gait features - body sway frequency, amplitude, stride length, and speed, along with pedestrian personal space and directional bias, are important parameters to be u…
Effects of Geometric Modelling and Blood Rheology in Patient-Specific Arterial Blood Flow Simulations with Speed-Accuracy Trade-Off Analysis
Rishi Kumar, K. Muralidhar, Indranil Saha Dalal
This study investigates the effects of geometric model reduction on blood flow simulations in the patient-specific descending aorta, followed by speed-accuracy trade-off analysis u…
Benchmarking Pedestrian Dynamics Models for Common Scenarios: An Evaluation of Force-Based Models
Kanika Jain, Shankar Prawesh, Indranil Saha Dalal +1
Extensive research in pedestrian dynamics has primarily focused on crowded conditions and associated phenomena, such as lane formation, evacuation, etc. Several force-based models…
Variable Goal Approach (VGA) Enhancing Pedestrian Dynamics Modeling
Kanika Jain, Anurag Tripathi, Shankar Prawesh +1
Pedestrian dynamics models have provided valuable insights into pedestrian interactions, collision avoidance, and self-organized crowd behavior using mathematical, computational, A…
Tunability of Dissipative Particle Dynamics simulations for Excluded Volume and Hydrodynamic Interactions in polymer solutions and Rheological predictions
Sanjay Jana, Venkata Siva Krishna, Praphul Kumar +1
Even though the Dissipative Particle Dynamics (DPD) has shown its worth in a variety of research areas, it has been rarely used for polymer dynamics, particularly in dilute and sem…
Mechanical response of van der Waals and charge coupled carbon nanotubes
Aningi Mokhalingam, Indranil S Dalal, Shakti S Gupta
This work investigates the mechanical response of single-walled carbon nanotubes (SWCNTs) coupled through van der Waals and electrostatic forces using molecular dynamic (MD) simula…
Petascale Brownian dynamics simulations of highly resolved polymer chains with hydrodynamic interactions using modern GPUs
Venkata Siva Krishna, Praphul Kumar, Bharatkumar Sharma +1
Brownian dynamics simulations of fairly long, highly detailed polymer chains, at the resolution of a single Kuhn step, remains computationally prohibitive even on the modern proces…
Effects of chain resolution on the configurational and rheological predictions from Brownian dynamics simulations of an isolated polymer chain in flow
Praphul Kumar, Indranil Saha Dalal
A reasonably accurate representation of a polymer chain is provided by beads connected with rods, or stiff, inextensible springs that mimic a single Kuhn step. Due to high computat…
Formulation of an equivalent GNF model as an efficient approximation for flow of polymer solutions described by FENE-P
Anirban Ghosh, Raghav Kumar, Indranil Saha Dalal
The molecular constitutive models, like FENE-P for polymer solutions, are known to have convergence issues at relatively larger flow rates. In this study, we investigate the possib…
Universal Nucleation Behaviour of Sheared Systems
Amrita Goswami, Indranil Saha Dalal, Jayant K. Singh
Using molecular simulations and a modified Classical Nucleation Theory, we study the nucleation, under flow, of a variety of liquids: different water models, Lennard-Jones and hard…
Seeding Method for Ice Nucleation under Shear
Amrita Goswami, Indranil Saha Dalal, Jayant K. Singh
Hydrodynamic flow can have complex and far-reaching consequences on the rate of homogenous nucleation. We present a general formalism for calculating the nucleation rates of simply…
Dissipative particle dynamics simulations of a single isolated polymer chain in a dilute solution
Praphul Kumar, Harishyam, Indranil Saha Dalal
In this study, we investigate the suitability of dissipative particle dynamics (DPD) simulations to predict the dynamics of polymer chains in dilute polymer solutions, where the ch…
