Modified Model of Heat and Mass Transfer Phase Change with High Density Ratio
In two phase fluid problem which involve phase change, the location of interface is changing and exceptional difficult to be captured accurately when the two immiscible fluid have high density ratio. By using general phase field model, the issue emerged with inaccurate location of moving ... En savoir plus
Visualization of Non-Invasive Electrical Impedance Spectroscopy on the Volar Forearm
Mathematical modeling and simulation of electrical fields through the human skin provide important insights into its electrophysiological state. As the human skin is a complex multi-layer entity of different compositions, we have chosen to select representative material properties to ... En savoir plus
Fabrication of 4130 Steel Powder for 3D Printing and Its Simulation Study
AISI 4130 grade is an alloy steel containing chromium and molybdenum as strengthening agents. The steel has a good strength, toughness, fatigue strength, weldability and machinability. These intriguing properties motivated us to make the 4130 powder via milling process and explore the ... En savoir plus
Adaptive Temperature Controller in Hemodialysis – Essential for Next-Gens
Nowadays, abnormal decline in blood pressure are common in end stage renal disease (ESRD) patients during hemodialysis treatment. The patient’s temperature instability plays a vital role in the onset of intradialytic hypotension, which implies that a slight variation in body temperature ... En savoir plus
Numerical Simulation and Experimental Validation of Single Clad Laser Metal Deposition
Laser metal deposition is widely adopted for coating, reparation and 3D printing. Using COMSOL, we have developed a numerical model with full coupling of laminar fluid flow and heat transfer. The Marangoni effect is considered to capture the enhanced convective heat transfer as well as ... En savoir plus
Diffusion-Limited Cluster Growth During Nucleation
Nucleation of clusters of a stable phase from a metastable phase is the initial stage of numerous phase transformations. Nucleation is often modeled by classical nucleation theory (CNT), but CNT is only applicable when growth of nucleating clusters is collision (or interface) limited. ... En savoir plus
Modelling of Heat Transfer in Different Materials in Cooking Vessels Using COMSOL
Cooking vessels are traditionally made of metals with high thermal conductivity, and mainly made out of aluminium, copper or stainless steel etc. With the wide availability of many different materials for making cooking pans, the project aims to investigate the contribution of the ...

Generalized Power Law Model of 3D Blood Flow in Bifurcated Stenosed Artery
Stenosis is a localize plaque that cause the vessel wall narrowed and causing an alternation in the flow structure which consequently reduced the fluid flow passing to the other organs and tissues. Previous researchers had proven that the formation of stenosis could disturb the normal ... En savoir plus
Dielectric Properties of Heterogeneous Media with Inclusion of Fractal Media
The aim of this research is to study the electrostatic properties of heterogeneous media that have fractal geometries. Currently, composite dielectrics are assumed to have regular geometric structures (integer-based dimensions) and an isotopic, homogeneous dielectric permittivity; but, ... En savoir plus
Computational and Experimental Study on Electrostatic Properties of Fractal Capacitors
The dielectric properties of heterogeneous media are of increasing interest as many applications exploit the usage of dielectric property detection in bio-imaging, scanning, microwave tomography and other electromagnetic applications. Using Laplace’s equation for non-integer dimensions, ... En savoir plus
