Bile duct inflammation and scarring, known as cholangiopathies, can disrupt bile flow, leading to liver damage and ...

Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris.

How restrictive are the assumptions governing its use? Here we give some examples. Consider the steady, flow of a constant density fluid in a converging duct, without losses due to friction (figure 14 ...

To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct (that is, the inlet and outlet flows do not vary with time). The inflow and ...

Pinwheels are pretty optimized from a design standpoint, and are so cheap and easy to build that putting a pinwheel to work as an HVAC duct flow meter seems like a great idea. Great in theory ...

Clean ducts allow air to flow more freely, which can reduce strain on your system and lower your energy bills. If you or ...

“If ducts are clean, your heating and air conditioning system run better and allergies can be reduced. A lot of filters don’t get everything or don’t allow air to flow. They are too ...

Steep inter compressor ducts (ICDs) are a promising solution for reducing the ... This allows a realistic inflow to the ICD to be generated. A detailed flow image can be obtained using boundary layer ...
