ABSTRACT
This thesis derives a first approximation model that will describe the flow of fluid in
microfluidic devices such as in microchannels, microdiffusers and micronozzles using
work modelling. The important parameter that is of concern is the flow
rates of these devices. The purpose of this work is to contribute to the physical
component of our interactive Virtual Reality (VR)-prototyping tool for MEMS, with
emphasis on fast calculations for interactive CAD design. Current calculations are too
time consuming and not suitable for interactive CAD with dynamic animations. This
work contributes to and fills the need for the development of MEMS dynamic
visualisation, showing the movement of fluid within microdevices in time scale.
Microfluidic MEMS devices are used in a wide range of applications, such as in
chemical analysis, gene expression analysis, electronic cooling system and inkjet
printers. Their ess lies in their microdimensions, enabling the creation of systems
that are considerably minute yet can contain plex subsystems. With this
reduction in size, the advantages of requiring less material for analysis, less power
consumption, less wastage and an increase in portability es their selling point.
Market size is in excess of US$50 billion in 2004, according to a study made by Nexus.
New applications are constantly being developed leading to cr
