Design And Manufacturing Of Impact Resisting Structures (Aluminium Foam)
(2009-09-02)
Metal foams have found increasing applications in a wide range of structural and functional products, due to their exceptional mechanical, thermal, acoustic and electrical properties and offer great potential for lightweight ...
Motion Space Analysis of Smooth Objects in Point Contacts
(2018-07-19)
The present work studies instantaneous motion of smooth planar and spatial objects in unilateral point contacts. The traditional first-order instantaneous kinematic analysis is found insufficient to explain many common ...
Dynamics of Bubbles and Drops in the Presence of an Electric Field
(2018-07-16)
The present thesis deals with two-phase electrohydrodynamic simulations of bubble and droplet dynamics under externally applied electric fields. We used the Coupled Level-Set and Volume-of-fluid method (CLSVOF) and two ...
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. ...
Vibrational Energy Harvesting : Design, Performance and Scaling Analysis
(2018-07-12)
Low-power requirements of contemporary sensing technology attract research on alternate power sources that can replace batteries. Energy harvesters function as power sources for sensors and other low-power devices by ...
