The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... Read More
The paper presents finite element simulation of a surface acoustic wave (SAW) linear motor. The function of SAW linear motor depends on the principle of friction drive provided by SAW propagating on a piezoelectric substrate. The SAW motor comprises of a slider driven by Rayleigh wave ... Read More
Sensors have diverse applications ranging from medical field to space explorations. They convert physical parameters such as temperature, pressure, humidity etc: - into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of ... Read More
In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and ... Read More
Fluid and structure Interaction analysis can be applied to versatile fields of engineering applications, helps in understanding the affects of one material on other, thereby reducing the effect of physical parameters like nonlinear response, vibration in flow channel etc. Rapid ... Read More
Due to the coupling of foam flow with foam generation step, the earlier studies on foam flow have not led to consistent results. An increase in flow rate to obtain ?P vs. Q data changes the foam under investigation itself. The controlled experiments carried out earlier in our group ... Read More
Metal-organic chemical vapour deposition (MOCVD) is a well-known process to produce high quality thin films that can protect, ennoble and functionalize metallic tools. To realize a high performance coating on a complex 3D mold surface, knowledge about the material formation from a ... Read More
With the advancements in aerospace technology, micro-electromechanical systems, hybrid data centres and microfluidics, the miniature size electronic chips in such applications are need of the century. The major challenge in microelectronic chips is to eliminate the generated heat for ... Read More
The paper illustrates the use of COMSOL (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function Ψm(x,y,z,t), m=1,4 as a solution to the time dependent Dirac equations. Once having Ψm(x,y,z,t), it can be used to compute the probability ... Read More
COMSOL Multiphysics is used to simulate natural convection and its impact on peak operating temperatures of solid-sate lighting in thermally adverse conditions. PDE modes in the general form are used in conjunction with a thin-surface conduction formulation in the weak form. COMSOL is ... Read More
