Multiple classes of heat exchangers exist to fill different needs. Some of the most common types are shell and tube exchangers and plate exchangers1. Shell and tube heat exchangers use a system of tubes through which fluid flows1. One set of tubes contains the liquid to be cooled or heated, while the second...

This video demonstrates separating neutrophils from tracheal secretions using a microfluidic device with spiral channels. The device achieves efficient separation based on cell size by utilizing varying thicknesses and trapezoidal-shaped channels. The interplay between forces results in large neutrophils accumulating near the inner wall while erythrocytes and mucin aggregates remain near the outer wall, ensuring effective neutrophil separation.

This video demonstrates the process for isolating spiral ganglion explants from the inner ear and co-culturing them with the organ of Corti on a multielectrode array. Spiral ganglia are carefully extracted and sectioned into smaller tissue sections or explants. These explants are cultured on the multielectrode array's active area to promote neuronal process outgrowth.

We present a protocol to culture primary murine spiral ganglion neuron explants on multi electrode arrays to study neuronal response profiles and optimize stimulation parameters. Such studies aim to improve the neuron-electrode interface of cochlear implants to benefit hearing in patients as well as the energy consumption of the device.
FAQs
Curved passages affect thermal performance in two related ways. As fluid follows the spiral, the changing direction promotes internal mixing, which supports heat transfer across the separating wall rather than relying only on less disturbed flow. At the same time, the coiled layout places substantial heat-transfer path within a compact device. This combination helps engineers pursue effective thermal management where equipment footprint matters.
Countercurrent operation improves temperature efficiency by sending the two fluids in opposing directions through their passages. That arrangement allows the temperature difference driving heat transfer to remain useful along more of the exchanger’s length, rather than diminishing as rapidly when both streams move together. Engineers therefore consider flow direction, not only exchanger size, when evaluating thermal performance.
Spiral tube heat exchanger performance is shaped by the relationship among channel geometry, fluid behavior, fouling, and available space. Curved channels can enhance mixing, while the enclosed passages keep the streams separated by a wall. The design is especially relevant for viscous fluids or services where fouling control matters, because those constraints can influence the practical value of compact thermal equipment.
Operation begins by directing the two fluids into separate coiled passages, with the wall maintained as the heat-transfer boundary. Engineers can select countercurrent flow when improving temperature efficiency is important, then integrate the exchanger into the surrounding thermal system. The essential design task is to preserve fluid separation while using the spiral path to support mixing and heat exchange.
Engineers may choose this equipment when a process needs thermal exchange in a relatively small footprint, or when viscous fluids and fouling control are important design concerns. Reported application areas include chemical processing, refrigeration, food production, and energy systems. The same compact approach can also support engineered laboratory systems, where space and effective thermal management influence equipment selection.
In engineering practice, the exchanger connects fluid handling with thermal management: two process streams retain separate flow paths while heat passes through the intervening wall. Its compact geometry can reduce equipment size, and its spiral channels can support heat transfer while occupying relatively little space. This makes the design relevant to both industrial installations and laboratory-scale engineered systems.
