In this paper, computational fluid dynamics (CFD) is utilized to characterize a prototype biolistic delivery system, the biomedical device based on the contoured-shock-tube design (CST), with the aim at investigating shocks induced flow instabilities within the contoured shock tube. The shock/interface interactions, the growth of perturbation at an interface between two fluids of different dens...

The Discrete Event System Specification (DEVS) has rarely been applied to the physics of motion. To explore the formalism’s potential contribution to these applications, we need to investigate the definition of moving gases, liquids, rigid bodies, and deformable solids. Here, we show how to use Cell-DEVS to analyze the movement and interactions of fluids using computational fluid dynamics (CFD)...

In the present paper, a finite volume method (FVM) based software is used in the simulation of simulation of non Newtonian flow between two parallel plates and flip chip packaging are presented. 3D of two parallel plates with different gap heights are developed and simulated by Computational Fluid Dynamic (CFD) code, FLUENT 6.3.26. The power law equation was used to describe the NonNewtonian be...

An effective way of improving the efficiency of tyre tube development is integrating, analysis and simulation into design, testing and manufacturing process. This allows designers and engineers to carry out analysis and simulation as an integrated part of tyre tube development process, and thus greatly reducing prototypes and physical testing. This paper deals with the analysis of tyre tube flu...

An analysis of the effects of the turbulent shear stress on cell culture in a stirred tank microcarrier bioreactor system using a synergistic combination of computational fluid dynamic (CFD)-based simulations and experiments is presented.

We present computational fluid dynamic (CFD) simulation of aggregation of two deformable cells in a shearflow. This work is motivated by an attempt to develop computational models of aggregation of red blood cells (RBCs). Aggregation of RBCs is a major determinant of blood viscosity in microcirculation under physiological and pathological conditions. Deformability of the RBCs plays a major role...
