Asymptotic Analysis Of The Dispersion Characteristics Of Structural Acoustic Waveguides
(2010-04-12)In this work, we study the coupled dispersion characteristics of three distinct structural-acoustic waveguides, namely: -(1) a two-dimensional waveguide, (2) a fluid-filled circular cylindrical shell and (3)a fluid-filledelliptic ... -
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 ... -

Blade Flutter in a Linear Cascade: Unsteady Loads and Flow Features in Subsonic and Transonic Flows
Vibration related issues like flutter can significantly limit the performance of aircraft engines and cause unwarranted cost and time overruns. The increased demand for more powerful yet compact engines has resulted in the ... -
Blast Loading on Plain and Perforated Tubes with High Explosives
According to the assessments of the United Nations, there are more than 100 million mines lying buried in various conflict zones of many countries in the world. As per their assessment, many thousand casualties happen ... -
Boundary layer transition with and without lateral divergence
Information on the transition processes in turbomachine boundary layers is important in computing schemes for predicting blockage, flow losses, separation, etc. Actual transition on turbomachine blades does not conform to ... -
Breakout Noise From The Coupled Acoustic-Structural HVAC Systems
(2010-07-19)Noise control in the heating, ventilation and air-conditioning (HVAC) systems is one of the critical design parameters in measuring the occupant comfort. The noise generated by air-handling units propagates through the ... -

A Capillary-fed Evaporative Microthruster for Micro/Nano Satellites
Small satellites offer a unique platform for short-term and low-cost communications and surveillance missions. They are essential for, scientific research, and technology demonstration due to their ability to provide rapid ... -
Casing boundary layer decelopment in axial impellers with TIP clearence
Casing wall boundary layers are heavily skewed under the action of secondary and tip clearance flows, relative wall motion and the transverse forces associated with the blade rows. The growth of the casing boundary layers ... -
CFD Studies Of Pulse Tube Refrigerators
(2012-12-06)The performance evaluation and parametric studies of an Inertance Tube Pulse Tube Refrigerator (IPTR) are performed for different length-to-diameter ratios, with the Computational Fluid Dynamics (CFD) package FLUENT. The ... -
Characterization Of Al-Si Alloy Engine Bores For Tribological Studies
(2013-06-06)Aluminum - Silicon alloys are recognized as appropriate materials for high performance cast components used in transportation powertrain applications. A combination of excellent wear resistance, good thermal conductivity ... -
Characterization of Corneal Lens of Drosophila melanogaster and its Genetic Mutants using Atomic Force Microscope and Scanning Electron Microscope
Drosophila melanogaster (the fruit fly) is a widely used model organism for the study of human disease condition and genetic pathways due to the high degree of gene conservation between fly and human. The compound eyes of ... -
Characterization of Flow Induced Noise Received by an Array Placed at Stagnation Point of an Underwater Axisymmetric Body
(2018-07-09)Given the interest on underwater axisymmetric cylindrical bodies for the development of high-speed underwater weapons, characterization of the boundary layer flow-induced noise received by a Sound NAvigation and Ranging ... -
Classical Approach to Understanding the Impact Dynamics of Hollow Droplets
Compound droplets are utilized in applications ranging from the preparation of emulsion to biological cell printing and additive manufacturing. Here, we report on the impact dynamics of a compound hollow droplet on a ... -
Coalescence of Polymeric Droplets
Coalescence is an energy minimization phenomenon in which two equilibrium droplets undergo a transition to attain a final equilibrium state, i.e., a coalesced state. Coalescence begins with a point contact between the ... -
A Comparative Study Of Different Numerical Techniques Used For Solving Incompressible Fluid Flow Problems
(2010-06-03)Past studies (primarily on steady state problems) that have compared the penalty and the velocity-pressure finite element formulations on a variety of problems have concluded that both methods yield solutions of comparable ...
