The commercial simulation software Comsol Multiphysics 4.2 was used to model and simulate ion-drag micro pump for three different configurations of collector electrode. The purpose of the simulation was to investigate the ways to improve the performance of the micro pump and analyze the effect of the electric field, fluid velocity and pressure gradient on the different design of the micro pump. The initial simulation patterns reveal the behavior of the electric field, fluid velocity and pressure gradient in the domain of each of the design of the micro pump. From the simulation results it is observed that at the top of the flow channel the fluid flow and pressure field is low because the driving electric body force is stronger near the electrodes surface and weaker at the top regions of the micro channel.

Numerical Modeling of the Dielectric Barrier Discharges Plasma Flow

Dielectric Barrier Discharge plasma actuator has been studied widely in this last decade but mostly the study is focusing on experimental research rather than mathematical modeling. The limitation with studying DBD plasma actuator experimentally is that it does not obtain direct information on the physics of the plasma flow, which is important in determining its efficiency. In this paper, we model the steady fluid model DBD plasma actuator mathematically. The preliminary result of the model are presented and discussed. To initiate the modeling process, the stream-function and vorticity are defined so that the Navier-Stokes momentum equation could be transformed into vorticity equation. The resulting two governing equations, which are vorticity and stream-function equations are solved numerically to obtain the vorticity of the flow in x and y directions. Finite difference method was adopted to discretize both equations and the system of equations is solved by the Gauss-Seidel method. Our numerical solutions show that the applied voltage plays an important role in the model. We found that as the applied voltage increases, the vorticity of the plasma flow also increases.

The purpose of this paper is to study the characteristics of single dielectric barrier discharge (DBD) plasma actuator through numerical modeling. A mathematical model that represents the physical system is presented and the numerical simulations for specific geometry are discussed in this paper. With this model, we can study the physics of the plasma flow. The formulation of the governing equations are divided into two since the physical system can be distinctly separated; one is the electrostatic part and the other is on the fluid flow. The electrostatic part is formulated using the Maxwell's equation which needs to be modified to incorporate the current frequency equation so that the system of equations becomes unsteady which is more realistic compared to a steady system of equations. The fluid flow part is formulated using the Navier-Stokes equations. The equations are re-represented using a vorticity term and stream function so that the flow characteristics can be clearly visualized. All equations are discretized using finite difference method. The discretized equations are then solved using the Gauss-Seidel iteration method. The numerical results show that the vorticity of the plasma is similar in pattern at each time interval. The highest magnitude of the vorticity occurs at the inner part near end of the upper electrode but this magnitude is different at each time. On varying the applied voltage, it is found that the peak vorticity also increases. Therefore, this shows that both the applied voltage and the geometry of the system influence the characteristics of the plasma flow.

Blood flow problem has been studied for centuries where one of the motivations was to understand the conditions that contribute to high blood pressure. This occurs when the blood vessel became narrowed from its normal size. This paper presents a mathematical modeling of the arterial blood flow which was derived from the Navier-Stokes equations and some assumptions. A system of nonlinear partial differential equations for blood flow and the cross-sectional area of the artery was obtained. Finite difference method was adopted to solve the equations numerically. The result obtained is very sensitive to the values of the initial conditions and this helps to explain the condition of hypertension.

Such flow is also known as thread annular flow and its study is motivated by the fact that thread injection is a surgical technique that allows the injection of porous medical implants, consisting of synthetic biocompatible materials, into the body in a minimally invasive way. The porous thread is stored on a spool and injected within a fluid by applying a pressure gradient. As most of the fluid flow is transparent and the actual fluid motion is not readily apparent to the human eye, thus modeling of the problem is needed. Past research has contributed into modeling the thread injection process mathematically where the thread is in a slightly eccentric position. This paper presents further insights into the behavior of the flow by obtaining the friction factor, which is a dimensionless parameter that expresses the linear relationship between the pressure gradient along the cylinder and the mean flow velocity through the cylinder, of the obtained flow. With the value of the friction factor, the amount of the head loss or pressure drop along the cylinder can then be calculated. Discussions are mainly on the comparison made with experimental results as well as numerical results for flow between concentric cylinders.

This phenomenon has urged an active participation in the research area of the security domain. One of the main areas of this security domain in providing confidentiality, authentication and data integrity is steganography. This paper proposes a steganography technique for hiding information in images through reparation technique in frequency domain. The purpose of reparation is to correct any static deviation from the cover image after embedding hidden message. The proposed technique is able to withstand visual attacks and statistical attacks. Thus, it can be used to strengthen the security of a steganography system. The proposed technique will be tested by using chi-square steganalysis.
