Manipulation of the fluid flow behavior in microfluidic with precision technique is crucial to satisfy the needs of miniaturized systems. Velocity measurement is one of the physical phenomena plays significant role to determine the performance of a microfluidic channel. This article presented the simulations of liquid with laminar flow over forward facing step microchannel to study the velocity profiles. Various Reynolds numbers and two different step heights have been used as main parameters. Higher Reynolds numbers and step height have been observed to produce higher flow velocity distribution. The peak velocity is found on the center of the channel across the x-axis.
