Flow and Windage Heating in Labyrinth Seals
(2017-11-24)
The ability to quantify leakage flow and windage heating for labyrinth seals with honeycomb lands is critical in understanding gas turbine engine system performance and predicting its component lifes. Variety of labyrinth ...
Power Loss Minimization for Drag Reduction and Self-Propulsion using Surface Mass Transpiration
(2017-11-29)
The remarkable efficacy with which normal surface mass transpiration (blowing and suction) alters a given base flow to achieve a desired predefined objective has motivated several investigations on drag reduction, ...
Viscous Vortex Method Simulations of Stall Flutter of an Isolated Airfoil at Low Reynolds Numbers
(2017-11-27)
The flow field and forces on an isolated oscillating NACA 0012 airfoil in a uniform flow is studied using viscous vortex particle method. The simulations are carried out at very low chord (c) based ...
Exploration And Assessment of HCCI Strategies for a Multi-Cylinder Heavy-Duty Diesel Engine
(2017-10-17)
Homogeneous Charge Compression Ignition (HCCI) combustion is an alternative combustion mode in which the fuel is homogeneously mixed with air and is auto-ignited by compression. Due to charge homogeneity, this mode is ...
Interaction of Bubbles with Vortical Structures
(2017-09-23)
Bubbly turbulent flows occur in a variety of industrial, naval and geophysical problems. In these flows, the bubbles in the flow interact with turbulence and/or vortical structures present in the continuous phase, resulting ...
Influence of Contact Stresses on Shape Recovery in Sputter Deposited NiTiCu Thin Films
(2017-10-05)
NiTiCu is a shape memory alloy that regains its original shape after large amount of shape changing deformation when heated above a critical temperature called reverse martensitic trans-formation temperature( Af). When ...
Geometric Reasoning with Mesh-based Shape Representation in Product Development
(2017-10-09)
Triangle meshes have become an increasingly popular shape representation. Given the ease of standardization it allows and the proliferation of devices (scanners, range images ) that capture and output shape information as ...
Specification and Verification of Tolerances for Parts with Free-Form Surfaces
(2017-11-27)
The need for increased product variety and improved aesthetics require the manufacturing enterprise to reduce time to market and to increase use of free-form surfaces in the form of the product. These changes lead to ...
Dynamics Of Cricket Song Towards Nature-inspired MEMS Speakers
(2016-09-15)
The clever designs of natural transducers are a great source of inspiration for man-made systems. At small length scales, there are many transducers in nature that we are now beginning to understand and learn from. Here, ...
Studies on the Design of Novel MEMS Microphones
(2018-02-17)
MEMS microphones have been a research topic for the last two and half decades. The state-of-the-art comprises surface mount MEMS microphones in laptops, mobile phones and tablets, etc. The popularity and the commercial ...
