Vented Hair Brush

Vented Hair Brush


Looking for a vented hair brush that won’t leave your hair a tangled mess? Look no further than our selection of vented hair brushes! We’ve got a brush for every hair type, so you’re sure to find the perfect one for you. Our vented hair brushes are easy on the hair, and easy to clean with our super strong bristles. Plus, they’re super lightweight and comfortable to hold in your hand as you brush away. Our vented hair brushes come with a nylon brush or an attachment brush, so you won’t find a brush that has both a nylon and a plastic comb in the same size! If you’re not exactly sure what features you want in a hair brush, or your looking for something a bit more specific, be sure to browse our selection of hair brushes in a larger variety of sizes and styles. So if you’ve always wanted to give your strands a little treat but didn’t know where to start, just give our vented hair brushes a try!Numerical investigation into the flow of aqueous solutions around and through the tip of a flexible, compliant microneedle array.
A microneedle (MN) is generally designed as a micrometer-scale sharp conical shape to deliver molecules into the skin of a patient via the stratum corneum. MNs can be used for numerous medical applications, including drug delivery and biosensors. MN-treating liquids, including saline, can be administered to the patient using the MN either while the MN is held within the patient or when the MN is retracted within the stratum corneum afterwards. In the former method, the flow of the liquid, which contains pharmaceuticals or biosensors, through the MN is not trivial because it can change the concentration of the liquid and its contact with the skin, resulting in inaccurate measurements of the liquid. This makes it challenging to accurately monitor and/or dose pharmaceuticals and biosensors. In this study, we present results from numerical simulations of an MN system composed of an array of 30 micron-scale needles joined by flexible polyimide rods. The effects of fluid velocity and needle tip flexibility are investigated by solving the Navier-Stokes equation in two- and three-dimensional domains. Our results show that the maximum velocity at the exit plane of the MN is significantly less than the jet velocity because of the large surface area facing the free stream. On the other hand, the increase in nozzle size does not produce corresponding drops of liquid because the surface area facing free stream becomes small. Lastly, the influence of the flexibility of the rods on the liquid jet is investigated by varying their Young’s modulus or surface roughness.Trying to Find the
