Flow physics of planar bistable fluidic oscillator with backflow limbs
AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract Fluidic oscillators (FOs) are used in a variety of applications, including process control and process intensification. Despite the simple design and operation of FOs, the fluid dynamics of FOs exhibit rich complexities. The inherently unstable flow, jet oscillations, and resulting vortices influence mixing and other transport processes.

Synaptic Mechanisms of Blast Induced Brain Injury
Frontiers in Neurology, 2016 Blast wave-induced traumatic brain injury (TBI) is one of the most common injuries to military personnel. Brain tissue compression/tension due to blast-induced cranial deformations and shear waves due to head rotation may generate diffuse micro-damage to

AIChE Journal, Volume 69, Issue 2, February 2023., 2023 Abstract The design of economically feasible and profitable production processes has driven companies toward integrated continuous manufacturing by reducing working volumes and increasing operating frequencies. Thus, the development of robust small‐scale devices capable of multivariate process optimization is essential.

Deep neural networks for fast acquisition of aortic 3D pressure and velocity flow fields [PDF]
, 2022 Computational fluid dynamics (CFD) can be used to simulate vascular haemodynamics and analyse potential treatment options. CFD has shown to be beneficial in improving patient outcomes. However, the implementation of CFD for routine clinical use is yet to be realised.

CFD Analysis of an Aerofoil [PDF]
International Journal of Engineering Research, 2014 In this report we have obtained the drag and lift forces using CFD which can also be determined through experiments using wind tunnel testing. In experimental setup, the design model has to be placed in the test section. This process is quite laborious & (surely) cost more than CFD techniques cost for the same.

PAMM, 2016 AbstractIn this contribution, an application of a computational aeroacoustic code as a hybrid Zonal LES tool is presented. The here used hybrid approach is based on a novel implementation of the Non‐Linear Perturbation Equations extended with fluctuating viscous terms, denoted as “Overset” since a perturbation analysis is performed on top of a ...
