Force moment partitioning and scaling analysis of vortices shed by a 2D pitching wing in quiescent fluid
Yuanhang Zhu, Howon Lee, Sushrut Kumar +3
We experimentally study the dynamics and strength of vortices shed from a NACA 0012 wing undergoing sinusoidal pitching in quiescent water. We characterize the temporal evolution o…
Effect of Antral Motility on Food Hydrolysis and Gastric Emptying from the Stomach: Insights from Computational Models
Sharun Kuhar, Jae Ho Lee, Jung-Hee Seo +2
The peristaltic motion of the stomach walls combines with the secretion of enzymes to initiate the process that breaks down food. Computational modelling of this phenomenon can hel…
Contribution of spanwise and cross-span vortices to the lift generation of low-aspect-ratio wings: Insights from force partitioning
Karthik Menon, Sushrut Kumar, Rajat Mittal
This study reports on the vortex-induced lift production mechanisms in low Reynolds number flows over low aspect-ratio rectangular wings. We use a rigorous force partitioning metho…
On query complexity measures and their relations for symmetric functions
Rajat Mittal, Sanjay S Nair, Sunayana Patro
The main reason for query model's prominence in complexity theory and quantum computing is the presence of concrete lower bounding techniques: polynomial and adversary method. Ther…
Significance of the strain-dominated region around a vortex on induced aerodynamic loads
Karthik Menon, Rajat Mittal
The ability of vortices to induce aerodynamic loads on proximal surfaces plays a significant role in a wide variety of flows. However, most studies of vortex-induced effects primar…
Tight Chang's-lemma-type bounds for Boolean functions
Sourav Chakraborty, Nikhil S. Mande, Rajat Mittal +3
Chang's lemma (Duke Mathematical Journal, 2002) is a classical result with applications across several areas in mathematics and computer science. For a Boolean function that ta…
