Understanding the dynamics of flames at small scales opens up opportunities to enhance the performance of small-scale power generation devices, micro-reactors, fire safety devices and numerous other systems that confine combustion to micro/meso scales. The current study investigates the dynamics of laminar premixed methane–air flames in meso-scale...

Liquid interfaces interacting with high-speed gas flows result in unsteady waves, atomization and countless applications. Here, we capture the intricate dynamics of a blast-induced air flow interacting with a liquid jet at the opening of a shock tube with a rectangular cross-section (aspect ratio 2:1). Features like a blast wave and the induced air...

This study comprehensively investigates the response of a combusting droplet during its interaction with a high-speed transient flow imposed by a coaxially propagating blast wave. The blast wave is generated using a specially designed miniature shock generator that produces blast waves using the wire-explosion technique, facilitating a wide range o...

The study comprehensively investigates the response of a combusting droplet during its interaction with high-speed transient flow imposed by a coaxially propagating blast wave. The blast wave is generated using a miniature shock generator which facilitates wide Mach number range ($1.01<M_s<1.6$). The interaction of the shock flow occurs in two stag...

The present study investigates the flame dynamics of a contactless burning fuel droplet under free fall subjected to a co-flow. The dynamic external relative flow established due to co-flow and droplet acceleration results in a series of droplet flame transitions. Different flame structures were observed, including a wake flame, reversed wake flame...

The study investigates the response of non-premixed jet flames to blast waves that are incident along the jet axis in the direction of the fuel jet. The flame is found to exhibit two major response patterns: re-attachment and extinction. Reducing the fuel jet Reynolds number (Re) and increasing the interacting blast wave Mach numbers (Ms) were foun...

The study investigates the response of the premixed jet flame during its interaction with the coaxial blast wave incident towards the flame. The blast wave is generated using a unique miniature shock generation facility that employs the wire-explosion technique, which enables a fine and easier control of the strength of the shock waves generated (M...

Understanding the dynamics of flames at small scales opens up opportunities to enhance the performance of small-scale power generation devices (which have potential appliances in micro-electro-mechanical systems), micro-reactors (which are extensively used in the field of quantitative chemistry), fire safety devices, and numerous other systems that...

Airfoils pitching in the stalled regime have been of keen interest in recent years due to their desirable aerodynamic force characteristics. This study numerically investigates the unsteady flow past a NACA (National Advisory Committee for Aeronautics) 0012 airfoil under sinusoidally pitching motion using a sharp interface immersed boundary framewo...

Airfoils pitching in the stalled regime have been of keen interest in recent years due to their desirable aerodynamic force characteristics. In this study, we are numerically investigating the unsteady flow past a NACA 0012 airfoil under sinusoidally pitching motion, using a finite volume based sharp interface immersed boundary solver. The flow is...
