During the transonic phase of a launch vehicle’s ascent, aerodynamic loads peak due to high freestream dynamic pressure and angle of attack. In addition to steady loads, significant pressure fluctuations arise from Shock ...

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 ...

This thesis focuses on the prediction of favourable pressure gradient turbulent boundary layer flows. Particularly, the focus is on mild favourable pressure gradient turbulent boundary layers and relaminarising turbulent ...

This thesis is a comprehensive experimental investigation of transitional and turbulent channel flow in the Reynolds number range of Reτ = 55 − 1559. Towards this objective, a new channel flow facility was designed and ...

Atmospheric and oceanic flows are often modeled as two-dimensional due to their large planar extents (∼ 1000 km) and small vertical extent (∼ 10 km). Most phenomena in these systems are governed by the theory of two-dimensional ...

The evolutions in the development of metal working fluid (MWF) from petroleum based products have brought remarkable changes to the present growing machining industry. The established MWF/Cutting fluids have reduced the ...

In space launch vehicles with liquid propulsion system, various sub-systems like gas bottles, anti-slosh baffles and fluid lines are placed inside the propellant tanks which become partially filled over time during flight. ...

A particular form of winged seed (samara) dispersal technique adopted by nature uses autorotative (unpowered rotation of the wing generating thrust force against gravity) descent; for eg. in Maple and Mahagony trees. ...

Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ...
