Dynamic behavior of electro-rheological fluid sandwich beams
Electrorheological (ER) fluids are fluids with controllable rheological properties. The study of change in rheology of suspensions due to application of electric field is of interest both from academic and industrial points ... -
Dynamic Response Of A Satellite With Flexible Appendages And Its Passive Control
(2010-11-25)Most present day spacecrafts have large interconnected solar panels. The dynamic behavior of the spacecraft in orbit can be modeled as a free rigid mass with flexible elements attached to it. The natural frequencies of ... -
Dynamic State Estimation Techniques For Identification Of Parameters Of Finite Element Structural Models
(2010-04-12)The thesis outlines the development and application of a few novel dynamic state estimation based methods for estimation of parameters of vibrating engineering structures. The study investigates strategies for data fusion ... -
Dynamic Strain Aging and Creep in near-α Ti Alloy, IMI834
IMI 834 is a near- Ti alloy used in high temperature applications such as compressor discs and blades of aero engines. Titanium alloys including IMI 834 are known to exhibit dynamic strain aging (DSA) over the temperature ... -
Dynamic viscosity of gas mixtures
An oscillating disc viscometer was designed and calibrated for the determination of viscosity of gases and gas mixtures at room temperature and pressure. The viscosity of oxygen, carbon dioxide and air were determined at ... -
Dynamically isotropic Gough-Stewart platform for micro-vibration isolation in spacecraft
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 ... -
Dynamics and Rheology of Non-colloidal Suspensions: Active and Soft Deformable Particles
Classical works on the suspensions of rigid spherical and ellipsoidal particles have been carried out by Einstein and Jeffery. However, in nature and industry, we come across materials that are either deformable or active. ... -
Dynamics And Stability Of A Launch Vehicle
(2011-07-08)Stability is an important criterion in the design and performance of launch vehicles. Present day launch vehicles have become more and more flexible due to the constraints of weight reduction, necessarily imposed for ... -
Dynamics and Stability of Multiple Jets in Geophysical Flows
(2018-04-18)The effect of rotation on the stability of multiple jets in planetary atmospheres is system- atically investigated. Typically in Jovian planetary atmospheres, multiple zonal jets have been observed and their morphology has ... -
Dynamics of Actuated and Interacting Swirl Premixed Flames in Model Gas Turbine Combustors
Lean premixed combustion is preferred in gas turbines because of the reduced (NOx) emissions. However, the combustors operating in lean premixed regime could suffer from problems like flame flashback, flame blowoff and ... -
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 ... -
