Comparison of air filtration efficiency measurements for pleated and flat sheet filtersFiltersMeasurementParticlesAir cleanersCleaningTestsIn the design of pleated air filters, the velocity of the flow at the filter surface is many times approximated as the "effective" velocity computed by assuming that ...

Two models of trachea and main bronchi with different conditions; actual model and simplified were developed for comparison purpose. Different conditions of inspiratory breathing, 5 l/min, 9 l/min, 12 l/min and 15 l/min were imposed at the outlet with different ratio, 55% for right bron...
Comparison of aircraft measurements with high resolution two dimensional simulations of air flow shows that simulations now efficiently and accurately capture wind disturbances (such as gusts and CAT) which develop within layers of vertical shear and waveb ...
The adverse impact of particulate air pollution on human health1,2 has prompted the development of purification systems that filter particulates out of air3,4,5. To maintain performance, the filter units must inevitably be replaced at some point, which requires maintenance, involves costs and gener...

the increase in removal efficiency is at the cost of respiratory resistance since a large surface area also leads to an escalating air viscous force between the fiber and the aerogel flow. Quality factor is an indicator to evaluate the performance of an air filter, which can be calculated as ...
