Pressure distribution characterization in forward facing step (FFS) microchannel using Ansys

The fundamental principles of fluid flow characteristics is vital in a microfluidic system. The integration of fluid flow exploitation and fabrication technologycreates good platform in various fields such as biomedical, clinical instrumentation and cell culture system. One of the important parameter to characterize a fluid is its pressure. In this article, characterization of pressure distribution in forward facing step (FFS) microchannel has been investigated using CFD-Ansys software. The primary goal of this research is to study the effect of the step height in FFS configuration on fluid flow pressure distribution. Hence, three different step heights have been employed as measurement comparison. Pressure drop trend was observed across the microchannel. The highest step height showed the highest pressure drop.
