Axially Homogeneous Turbulent Convection at High Rayleigh Numbers : Scaling Laws for Flux and Spectra
(2018-05-30)Natural turbulent convection studies encompass a wide range of flows occurring in nature, for example, atmospheric and oceanic flows, con-vection in the Earth’s mantle, convection in the stars and also in many engineering ... -
Buoyancy Driven Turbulence In A Vertical Pipe
(2011-06-24) -
Creation of an Orderly Jet and Thrust Generation in Quiescent Fluid from an Oscillating Two-dimensional Flexible Foil
(2018-02-22)In nature, many of the flapping wings and fins in swimming and flying animals have various degrees of flexibility with strong and coupled solid-fluid interactions between the structure and the fluid. In most cases, the ... -
Design and Development of a Novel Solar Thermal Receiver
One of the most widely used solar collectors for process heating and large scale electricity generation is the parabolic trough collector (PTC), in which a tube placed at the focus of the parabola receives concentrated ... -
Development And Performance Evaluation Of An Indirect Evaporative Air Cooler
(2014-09-09)Evaporative cooling is an alternative and efficient method of cooling in dry climates. When a liquid evaporates into the surrounding gas, the energy required for the change of phase produces a cooling effect. The wet bulb ... -
Droplet Growth in Moist Turbulent Natural Convection in a Tube
(2018-07-04)Droplet growth processes in a cumulus cloud, beginning from its inception at sub-micron scale up to drizzle drop size of few hundred microns, in an average duration of about half hour, has been a topic of intense research. ... -
The Dynamics Of Erosion Of Gradient-Zone In Solar Ponds

Evaporation of Water from Soil-like, Leaf-like Surfaces and Unconventional Porous Media
Evaporation is one of the inherent processes of our planet earth as an ecosystem. Water bodies, earth’s surface and vegetation all contribute significantly towards the total evaporation which eventually leads to the formation ... -
Experimental and Numerical Investigation of an Evaporating Meniscus in a Capillary Slot : Microscale and Pore Scale Studies
(2018-08-09)An evaporating meniscus formed by a wetting °uid in a heated capillary slot with capillary driven °flow is numerically and experimentally investigated at the microscale and pore scale. In the microscale analysis, the ... -
An Experimental Study Of Instabilities In Unsteady Separation Bubbles
(Indian Institute of Science, 2007-06-11)The present thesis is an experimental study of some aspects of unsteady two dimensional boundary layers subject to adverse pressure gradient. An adverse pressure gradient usually leads to boundary layer separation or an ... -
Experimental Study of Patterns in Hydrodynamically Deposited Dispersed Phase of CaCO3 on Surfaces of Straight Cylindrica Silica Tubing
(2018-08-13)Deposition of dispersed phase from flowing dispersions onto a substrate surface is of utmost relevance for various industrial processes like fouling of sparingly soluble salts, such as CaCO3 and CaSO4 in heat exchangers and ... -
Experiments On Natural Ventilation In A Room And Real Source-Sink Pairs
(2010-09-06)The present work consists of two parts: experimental study of natural ventilation in a model room and the flow associated with a source-sink pair. The first part describes the natural ventilation of a model room of size ... -
Experiments On Rolling Sphere Submerged In An Incompressible Fluid
(2016-09-15)Experiments are done using a smooth solid rigid homogeneous acrylic sphere rolling on an inclined plane which is submerged in water. The motivation for these experiments comes from a need to understand a class of solid-fluid ... -
Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ... -
Force Measurements On Rigid And Flexible Oscillating Foils
(2013-10-04)In the present work, we experimentally study thrust generation from sinusoidally pitched rigid and flexible foils immersed in a uniform flow. The flexible foils are made by attaching a flexible flap of known flexural ... -
Gust Rejection in Insect Flight
Large commercial and military aircraft can fly in turbulent wind conditions except in extreme weather events like cyclones. Smaller man-made vehicles like Micro aerial vehicles (MAVs) and Nano aerial vehicles (NAVs) are ... -
Hydrodynamics Of An Oscillating Foil With A Long Flexible Trailing Edge
(2010-09-24)In nature, many swimming and flying creatures use the principle of oscillatory lift-based propulsion. Often the flapping element is flexible, totally or partially. The flow dynamics because of a flexible flap is thus of ... -
Investigations On High Rayleigh Number Turbulent Free Convection
(Indian Institute of Science, 2005-08-31)High Rayleigh number(Ra) turbulent free convection has many unresolved issues related to the phenomenology behind the flux scaling, the presence of a mean wind and its effects, exponential probability distribution ... -
Sedimentation Of Heavy Particles In Turbulence
(2010-08-06)Behavior of particles in buoyancy driven turbulent flow at Ra ≈ 10º is investigated experimentally. The volume fraction of the particles is low enough for the inter particle influence to be neglected, the mass loading ...
