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

Modeling and Simulation of Pressure Seals

R. P. Ruby[1], G. Kulkarni[1], U. Kanade[1]
[1]Noumenon Multiphysics Pvt. Ltd., Pune, Maharashtra, India

Seals leak primarily at the interface between seal and cavity (Figure 1). At a microscopic level, the interface between the seal and cavity consists of regions of contact between the two elements, and voids. The voids are connected to each other, forming a microscopic system of caverns ... Read More

Plasmonics Based Keys for Image Encryption that Uses Exclusive OR Logic Operation

N. K. Nishchal[1], A. Fatima[1], I. Mehra[1], D. Kumar[1]
[1]Indian Institute of Technology Patna, Patna, Bihar, India

Optical encryption has become a significant research field due to its remarkable advantages [1-5]. The unique features of plasmonics have drawn researchers’ attention towards the role which it can play in information security [3 & 4]. The electric field is greatly enhanced when a ... Read More

Comparative Study on 3D Modeling of Breast Cancer Using NIR-FDOT

S. Peter[1]
[1]Christ University, Bengaluru, Karnataka, India

Fluorescence Diffuse Optical Tomography (FDOT) uses Near Infra-Red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such ... Read More

Simulations of Negative Curvature Hollow-core Fiber

J. Zhang[1], Z. Wang[1], J. Chen[1]
[1]College of Optoelectronic Science and Engineering, National University of Defense Technology, Changsha, Hunan, China

COMSOL Multiphysics® software was used to simulate and analyze the transmission attenuation spectra of the negative curvature hollow-core fiber (NCHCF) over the wavelength from 2.7 μm to 4.2 μm. The effect of thickness of capillaries and the effect of the distance between the capillaries ... Read More

Phase-field Modeling of Widmanstätten Ferrite Formation During Austenite to Ferrite Transformation in Fe-C Alloy

L. Zhang[1], Y. Shen[1]
[1]School of Materials Science and Engineering, Shanghai Jiao Tong University, Shanghai, China

The transformation of austenite (A) to ferrite (F) in steels, which is technologically important and of fundamental interest, still remains less well understood in some aspects. At intermediate undercooling F grows with a plate-like morphology (widmanstätten). Some calculations, which ... Read More

Updated Results of Singlet Oxygen Modeling Incorporating Local Vascular Diffusion for PDT

R. Penjweini[1], M. M. Kim[1], T. C. Zhu[1]
[1]Department of Radiation Oncology, University of Pennsylvania, Philadelphia, PA, USA

Introduction: Singlet oxygen (¹O₂) has a critical role in the cell-killing mechanism of photodynamic therapy (PDT). Therefore, in this study, the distance-dependent reacted ¹O₂ is numerically calculated using finite-element method (FEM). Herein, we use a model [Ref. 1] that has been ... Read More

The Simulation of Motion of a Slider upon a Stator Due to Frictional Force Using COMSOL Multiphysics® Software

H. B. Nemade[1]
[1]Indian Institute of Technology Guwahati, Guwahati, Assam, India

The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction ... Read More
