Large Eddy Simulation of Multiphase Flows
(2018-06-05)
Multiphase flows are a common phenomenon. Rains, sediment transport in rivers, snow and dust storms, mud slides and avalanches are examples of multiphase flows occurring in nature. Blood flow is an example of multiphase flow ...
Edge Effect of Semi-Infinite Rectangular Posts on Impacting Drops
(2018-05-30)
The inhibiting effect of a sharp edge on liquid spreading is well observed during drop interaction with textured surfaces. On groove-textured solid surfaces comprising unidirectional parallel grooves, the edge effect of ...
A Design Procedure for Flapping Wings Comprising Piezoelectric Actuators, Driver Circuit, and a Compliant Mechanism
(2018-06-05)
Flapping-wing micro air vehicle (MAV) is an emerging micro-robotic technology, which has several challenges toward its practical implementation. Inspired by insect flight, researchers have adopted bio-mimicking approach ...
Time-Optimal Guidance for Impact Angle Constrained Interception of Moving Targets
(2018-05-30)
Various unmanned missions deploy vehicles such as missiles, torpedoes, ground robots, and unmanned aerial vehicles. Guidance strategies for these vehicles aim to intercept a target point and satisfy additional objectives ...
Application Of Controlled Random Search Optimization Technique In MMLE With Process Noise
(Indian Institute of Science, 2006-08-08)
Generally in most of the applications of estimation theory using the Method of Maximum Likelihood Estimation (MMLE) to dynamical systems one deals with a situation where only the measurement noise alone is present. However ...
A Numerical Study of Changes to Flow Organization and their Prognostic Measures
(2018-05-23)
Flow induced self-oscillations cause acoustic pressure oscillations of large amplitude in pipe flows. If Reynolds number is treated as a parameter, these floinduced oscillations occur only at discrete and critical values ...
Closed-form Solutions For Rotating And Non-rotating Beams : An Inverse Problem Approach
(2012-12-04)
Rotating Euler-Bernoulli beams and non-homogeneous Timoshenko beams are widely used to model important engineering structures. Hence the vibration analyses of these beams are an important problem from a structural dynamics ...
An Autonomous Guidance Scheme For Orbital Rendezvous
(Indian Institute of Science, 2005-07-15)
The word 'rendezvous' implies a pre-arranged meeting between two entities for a specific purpose. This term is used in the study of spacecraft operations, to describe a set of maneuvers performed by two spacecraft in order ...
NEW PERSPECTIVES FOR ANALYZING THE BREAKUP, ENVIRONMENT, EVOLUTION, COLLISION RISK AND REENTRY OF SPACE DEBRIS OBJECTS
(Indian Institute of Science, 2005-03-10)
In the space surrounding the earth there are two major regions where orbital debris causes
concern. They are the Low Earth Orbits (LEO) up to about 2000 km, and Geosynchronous Orbits (GEO) at an altitude of around 36000 ...
Wing in Ground Effect
(2017-12-01)
The thesis presents a two pronged approach for predicting aerodynamics of air- foils/wings in the vicinity of the ground. The first approach is effectively a model for ground effect studies, employing an inexpensive Discrete ...
