Interstitial fluid flow is elevated in solid tumors and can modulate tumor cell invasion. Here we describe a technique to apply interstitial fluid flow to cells embedded in a matrix and then measure its effects on cell invasion. This technique can be easily adapted to study other systems.

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana The objective of this video is to describe recent advancements of computational fluid dynamic (CFD) simulations based on patient- or animal-specific vasculature. Here, subject-based vessel segmentations were created, and, using a combination of open-source and commercial tools, a high-resolution numerical solution was determined within a flow model.

Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2. During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

Measurement of Fluid Pressure

Fluid pressure is commonly measured using devices called manometers, which rely on liquid columns to indicate pressure differences. The height of a liquid column in a manometer reflects the pressure exerted by the fluid, providing a simple yet effective means of measurement. Different types of manometers serve specific purposes based on their configurations and the type of fluids involved. A basic form of manometer is the piezometer, a vertical tube open at the top and filled with the same...
FAQs
Volumetric flow rate describes the amount of fluid moving through a system over time, whereas mass flow rate describes the corresponding amount by mass. Selecting between them depends on what the experiment or device must quantify. This distinction helps researchers characterize transport consistently when evaluating biological systems, engineered tissues, or fluid-handling components.
Different approaches obtain flow information from different signals, including fluid velocity, pressure differences, or changes in fluid properties. Flow meters, particle tracking, and microfluidic sensors therefore suit different flow conditions. Matching the sensing principle to the channel, vessel, or device helps produce measurements that represent system performance rather than an unsuitable operating condition.
Particle tracking is useful when fluid motion can be represented by observing particles, while flow meters and microfluidic sensors provide alternatives based on flow conditions and device format. The choice is not universal: researchers select the approach that best matches the system being studied. This comparison is especially relevant when examining transport inside small or engineered biological environments.
First identify whether the experiment requires volumetric flow rate, mass flow rate, or information related to velocity, pressure differences, or fluid properties. Then consider the channel, vessel, or device in which movement occurs and compare suitable flow meters, particle-tracking methods, or microfluidic sensors. This planning supports measurements that are relevant to the intended biological or engineering question.
In bioengineering, measurements can characterize blood flow and monitor perfusion in engineered tissues. These data describe how fluid transport occurs through biological or tissue-engineered systems, helping researchers evaluate whether a device or construct performs as intended. The resulting information also supports investigation of how fluid movement influences cells and tissues.
Flow measurements help control drug-delivery systems and evaluate lab-on-a-chip devices by quantifying transport through their fluidic components. Monitoring flow provides evidence about device performance and supports reproducible experiments. In bioengineering research, these measurements connect fluid behavior with practical goals such as controlled delivery, reliable operation, and assessment of microfluidic device function.
