Dielectrophoresis (DEP) is an effective method to manipulate cells. Printed circuit boards (PCB) can provide inexpensive, reusable and effective electrodes for contact-free cell manipulation within microfluidic devices. By combining PDMS-based microfluidic channels with coverslips on PCBs, we demonstrate bead and cell manipulation and separation within multichannel microfluidic devices.

Uniform Depth Channel Flow

Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...

Open channel flow, where a fluid flows with a free surface exposed to the atmosphere, is primarily governed by gravitational and surface effects, distinguishing it from closed conduit or pipe flow. In open channels such as rivers, canals, and artificial channels, energy analysis provides valuable insights into flow behavior and the relationship between depth, velocity, and slope.Specific Energy and Flow DepthIn open channel flow, the specific energy, E, combines the gravitational potential...

To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water. Using the values of the cross-sectional area and the wetted perimeter, determine the hydraulic radius by...

A technique for performing quantitative three-dimensional (3D) imaging for a range of fluid flows is presented. Using concepts from the area of Light Field Imaging, we reconstruct 3D volumes from arrays of images. Our 3D results span a broad range including velocity fields and multi-phase bubble size distributions.
FAQs
Flow distribution in a multi-channel network reflects both channel geometry and network resistance. A branch with different dimensions or resistance will receive a different share of the fluid when the system is driven by a pump or pressure difference. Designing these features therefore determines how evenly pathways are supplied, which is important when parallel processing must remain controlled.
Pumps and pressure differences set the flow rate, but they do not alone determine how fluid divides among branches. Channel geometry and network resistance shape that distribution, while valves, sensors, or separate inlets provide additional control over pathway conditions. Combining these elements lets a system coordinate multiple flow environments for biological processing.
Coordination matters because separate pathways can support different spatial flow environments or changing conditions within one platform. The arrangement can be used for controlled transport, mixing, or processing in parallel, rather than treating the entire device as a single uniform route. In bioengineering, this supports experiments involving cells, biomolecules, or engineered tissues.
To configure a Multi-channel Flow System for a bioengineering experiment, researchers establish separate inlets or coordinated pathways, choose channel geometry and network resistance, then use pumps or pressure differences to regulate flow. Valves and sensors can control conditions, while the resulting arrangement provides controlled transport or processing across the selected pathways.
Applications extend across cell behavior studies, drug delivery, tissue models, and scalable biological manufacturing. The system can handle cells, biomolecules, and engineered tissues while maintaining spatially distinct or dynamically changing flow environments. This makes the approach relevant when researchers need to examine biological responses or process materials under controlled transport conditions.
The main experimental value comes from controlling where and when fluid moves. Researchers can use the resulting spatially distinct or dynamically changing environments to study cell behavior, drug delivery, or tissue models. In manufacturing contexts, coordinated pathways support processing in parallel, connecting flow-system design with scalable biological production.
