The extensional flow of viscoelastic flow is encountered during fibre spinning processes. A variety of polymers such as polyesters, polyacrylonitrile, rayon, acrylic, spandex etc are manufactured using this process. In the spinning process, polymer melt/ solution is extruded in the form ... En savoir plus
Increased light scattering have been found to improve the short-circuit current of photovoltaic devices. In this paper we have tried to optimize the dimensions of ZnO nanorods to achieve this. Scattering efficiency of these nanorods was evaluated by solving Maxwell’s electromagnetic ... En savoir plus
BAW (Bulk Acoustic Wave) resonators are rapidly growing highly integrated devices with wide range of applications in wireless domains. Fabrication of thin film BAW resonators are highly challenging over material selections and measures of materials. RF properties of BAW resonators ... En savoir plus
In this paper, a two dimensional finite element based microstructural model is constructed using Voronoi tessellation for representing polycrystalline material. Elastic wave propagation and Heat diffusion studies are then performed on constructed microstructure model.Computational issues ... En savoir plus
The paper presents a method of extraction of electrical equivalent circuit of a one port surface acoustic wave (SAW) resonator from the results of simulation based on finite element method (FEM) using COMSOL Multiphysics software. A one port SAW resonator consists of large number of ... En savoir plus
A Shock absorber is a mechanical device engineered to absorb high impact load and provide comfort while riding on a rough roads. Suspension springs are the key components of a shock absorber to resist critical impact loads and provide ride comfort. The cylindrical spring designs comes ... En savoir plus
Casting product performance depends on material, flow, Process Temperature, Solidification, Shrinkage and residual stress. In a casting process, not all available resources are utilized effectively which results in low quality of casting, defects and metal wastage. Physics based modeling ... En savoir plus
A lithium-ion battery comprises of two intercalating electrodes separated by a membrane, sandwiched between aluminum and copper current collecting plates. The battery performance depends upon several parameters and its operating conditions. In this work we developed a model for a lithium ... En savoir plus
In the work presented, we generated a microfluidic design to obtain different concentration profiles in transverse channels. We also generated another microfluidic design with a flow-fewer zone which we think will help study the cells in a shear free environment. We simulated these ... En savoir plus
This paper deals with the numerical experiments for early prediction of muffler performance at the design stage. In this experiment a Reactive Muffler is developed and validated numerically compared to traditional built and test process. En savoir plus
