Trapping DNA Molecules in Fluids Using Electrokinetic Effects Generated by Different Electrode Geometries
In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of ... Per saperne di più
Early Breast Cancer Detection using Patient Symptomatic Breast Images by Finite Element Analysis Aided by COMSOL
In this project, we attempted to determine the drug concentration in a breast cancer tumor after a drug has been delivered. We created a COMSOL Multiphysics® finite element model. We investigated the relationship between drug delivery efficiency and parameters such as diffusivity, ... Per saperne di più
CFD Analysis of Ejectors
Ejectors are the devices used to carry out mixing and recompression of two fluid streams, one with higher energy and the other with lower Energy. The high energy fluid is passed through the converging nozzle of ejector to very high velocities which in turn creates suction and draws the ... Per saperne di più
Low Reynolds Number Flow Around a Flying Saucer Micro Air Vehicle
The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we ... Per saperne di più
Models with Helical Symmetry Studied in a 2D Plane
Partial differential equations (PDEs) in multiple dimensions may often be solved in a lower dimension if the problem domain contains a symmetry (cylindrical, spherical, translational, etcetera). For problems involving PDEs with helical symmetry we propose a method, with both low ... Per saperne di più
