This manuscript describes how to create regular bedforms in a flume, visualize flow through the bedforms, and use computer simulations to simulate the hyporheic flow. The computer simulations compare well with the experimental observations. This coupled simulation and experiment is well-suited for both research and educational purposes.

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.

We describe a novel surgical method for catheterizing 'intestinal loops' within the ileum of sheep. Once animals have recovered from surgery and have cleared antibiotics and analgesics, multiple treatments can be deposited directly in loops via the catheters.

An efficient way to gain insight into how humans navigate themselves in three dimensions is described. The method takes advantage of a motion simulator capable of moving observers in ways unattainable by traditional simulators. Results confirm that movement in the horizontal plane is underestimated, while vertical movement is overestimated.
FAQs
The pump establishes fluid movement, while adjustable resistance changes how readily the fluid passes through the circuit. Pressure and flow sensors record the resulting conditions at relevant points, allowing investigators to examine how a device performs under selected hemodynamic states. This relationship helps distinguish whether performance changes arise from altered flow, pressure, resistance, or their combined effects.
Adjustable resistance allows the circuit to reproduce more than one flow condition instead of restricting evaluation to a single operating state. Sensors then provide quantitative measurements of pressure and flow, creating evidence that can support device comparisons and reveal performance differences. Together, these components make the test environment controlled, measurable, and repeatable.
A controlled loop permits repeated assessment without immediate reliance on patients. Investigators can expose a device to selected hemodynamic conditions, measure its response, and identify design limitations before clinical use. This staged evaluation can improve understanding of relevant fluid dynamics and provide practical information for refining devices intended to function within physiological systems.
A basic arrangement includes a pump, tubing, reservoirs, a test section, adjustable resistance, and pressure and flow sensors. The pump drives fluid through the circuit, the test section holds the device or system under evaluation, and the sensors quantify its response. Changing the resistance and monitored conditions enables structured testing across selected operating states.
Investigators place each device in the test section and run fluid through the same controlled circuit while monitoring pressure and flow. They can apply selected hemodynamic conditions and use the resulting measurements to compare performance across devices. Keeping the circuit and adjustable conditions controlled helps separate device-related differences from changes caused by the testing environment.
Flow loop simulation supports testing of blood pumps, catheters, vascular grafts, and other technologies whose function depends on fluid movement. The method can reveal how each design responds to controlled pressure and flow conditions. These results help identify limitations, compare alternatives, and guide development before a technology reaches clinical evaluation.
Measurements from pressure and flow sensors provide quantitative evidence of device performance under selected conditions. Researchers can use these results to compare designs, detect performance limitations, and examine fluid dynamics relevant to physiological operation. In medicine, the findings may inform development of safer or more suitable flow-dependent technologies before clinical use.
