This is a 3D model of chemical binding kinetics in a millimeter-scale biosensor. The objective of the model is to investigate the effects of various kinetic parameters on the simulated response. A general objective of modeling such problems (not covered here) could be to evaluate the effectiveness of the mathematical model for extracting kinetic parameters from the sensogram.
CFD-VisCART is an automated 3D viscous unstructured adaptive Cartesian grid generation tool for handling complex geometries. This tutorial describes the steps for generating a Cartesian grid with different mesh resolutions on various geometries using CFD-VisCart.
The steady state conductive heat transfer to the air-gap between infinitely long concentric thick-walled cylinders is modeled and compared with an analytical solution. This is a step-by-step guided introductory tutorial for setting up a heat transfer model in CFD-ACE+.
This simulation models a two-dimensional cross channel geometry
connecting four sample reservoirs. The process considered is
electroosmotic driven flow from reservoir 1 to reservoir 2. The model
examines the coupled fluid flow and electrostatic field at steady state. Electroosmotic flows are being considered for possible use in a number of biomedical applications involving flow in flow channels such as needless blood sampling for glucose testing.
This tutorial demonstrates the generation of a 3D geometry model and its discretization into a 3D structured grid. A Tesla-type valve geometry is used for this demonstration.
User subroutines are built as Dynamic Link Libraries (DLL files for Windows) or shared objects (.so files for UNIX platforms). The shared libraries are then linked with CFD-ACE-SOLVER such that a two way communication between the solver and the user defined input is established.
The steady-state forward and reverse flow characteristics of a Tesla-type valve are investigated using CFD-ACE+. A Tesla-type valve is one of the no-moving-parts (NMP) type valves used in micropumps for microelectromechanical system (MEMS) devices.
Bead based Immunoassays are very popular for clinical applications involving biochemical and biological detections. The geometry considered is a Y-junction employed in many micro-fluidic systems.
Microwells are being increasingly used in Ultra High Throughput Screening (Ultra HTS) systems, where they are an integral component of Dynamic Microarrays. Pressure driven flow is used to drive liquid flow to the Microwell. Because of the extremely small length scales involved, the surface tension forces are significant. This simulation investigates the filling of a Microwell.
