Studies for Design of Layered Ceramic Armour Inspired by Seashells
(2018-06-26)
Pearly layers in seashells, also known as nacreous layers, are reported to be three orders of magnitude tougher than their primary constituent, aragonite. Their high toughness is attributed to a particular structure of ...
Design and Development of a Three-degree-of-freedom Parallel Manipulator to Track the Sun for Concentrated Solar Power Towers
(2018-05-21)
In concentrated solar power (CSP) stations, large arrays of mirrors which are capable of changing its orientation are used to reflect the incident solar energy to a stationary receiver kept at a distance. Such mirrors are ...
Influence of Hydrodynamic Slip on the Wake Dynamics and Convective Transport in Flow Past a Circular Cylinder
(2018-06-14)
Hydrodynamic slip is known to suppress vorticity production at the solid-fluid boundary in bluff body flows. This suppression combined with the enhanced vorticity convection results in a substantial reduction in the unsteady ...
Numerical Simulation of a High-speed Jet Injected in a Uniform Supersonic Crossflow Using Adaptively Redistributed Grids
(2018-05-22)
Minimizing numerical dissipation without compromising the robust shock-capturing attributes remains an outstanding challenge in the design of numerical methods for high-speed compressible flows. The conflicting requirements ...
Transition and Acoustic Response of Vortex Breakdown Modes in Unconfined Coaxial Swirling Flow and Flame
(2018-07-19)
The efficient and enhanced mixing of heat and incoming reactants is achieved in modern gas turbine systems by employing swirling flows. This is realized by a low velocity region (internal recirculation zone -IRZ) zone ...
Numerical Studies On Ductile Fracture Of Pressure Sensitive Plastic Solids
(2010-07-08)
Experimental studies have shown that the yield strength of many important engineering materials such as polymers, ceramics and metallic glasses is dependent on hydrostatic stress. In addition, these materials may also ...
Contact Mechanics Of Layered Structures
(2009-06-30)
Contact mechanical study of layered structures is useful to various fields of
engineering, such as - mechanical engineering, civil engineering, materials engineering and biomechanics. Thin hard film coating on a compliant ...
Role of Microstructure in the Mechanics of Soft Matter
(2018-07-16)
Materials which exhibit non-linear mechanical behaviors under large deformations are generally classified as “soft matter”. Elastomers represent an important class of soft materials which have wide commercial applications ...
Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces
(2010-07-01)
The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ...
Dynamics of Hollow Cone Spray in an Unconfined, Isothermal, Co-Annular Swirling Jet Environment
(2018-07-20)
The complex multiphase flow physics of spray-swirl interaction in both reacting and non-reacting environment is of fundamental and applied significance for a wide variety of applications ranging from gas turbine combustors ...
