Self-propelled oscillating foils are simple yet useful models that can be used to explore the physics of oscillatory bio-locomotion. In this investigation, we explore the self-propulsion characteristics of a rigid NACA0015 ...

Thin fluid film flows are ubiquitous in nature and many industrial applications. Such flows are characterized by having the thickness in one direction being much smaller than the characteristic length scales in the ...

Evaporation of polymer droplets is an active area of interest due to its applications in systems such as ink jet printing, thin films, spray combustors to name a few. Thus, understanding complex dynamics of evaporating ...

Adsorption cooling systems are evolving as promising complements to conventional vapor compression refrigeration (VCR) systems because of their ability to utilize low-grade heat sources such as industrial waste heat, solar, ...

Rotating components such as reaction wheels and momentum wheels on spacecraft generate micro-vibrations up to 250 Hz during on-orbit operations. While the use of Gough-Stewart Platforms (GSPs) for six degrees of freedom ...

Due to several perceived advantages, supercritical Carbon dioxide (sCO2) cycles are viewed as potential replacements for steam-based power generation. Their successful deployment depends on several factors - one important ...

Centrifugal compressors are widely employed in turbochargers and small gas turbines due to their ability to achieve high compression per stage. These compressors consist of a rotating impeller and a static diffuser, which ...

Bubbly turbulent flows occur in many places, such as in chemical reactors and geophysical applications, besides interest from the drag reduction perspective using injected bubbles in a (water) boundary layer. In these ...

The heat and moisture loss from water surfaces are important in many natural and industrial systems. For example, the natural water cycle where water evaporates from the lakes, rivers, and seas, rises in the atmosphere, ...

Compound droplets are utilized in applications ranging from the preparation of emulsion to biological cell printing and additive manufacturing. Here, we report on the impact dynamics of a compound hollow droplet on a ...
