Numerical analysis of bladeless ceiling fan: An effective alternative to conventional ceiling fan
2022, Journal of Wind Engineering and Industrial AerodynamicsCitation Excerpt :The surrounding air upstream of the fan rushes towards the low-pressure zone, thus forming the part of bladeless fan flow. The phenomena of inducement and entrainment are not new and are being actively used in a variety of applications such as ejector pumps, nebulization, aerospace, flow control, and jets (Rusly et al., 2005; Collis et al., 1990; Quackenbush et al., 1996; Englar et al., 1994; Ho and Gutmark., 1987). Bladeless desktop fan patented by Dyson™ has brought a revolution in the fan industry.

2011, TuberculosisCitation Excerpt :Likewise, forceful deep inhalations that are recommended while inhaling aerosol, may be difficult for elderly and severely ill patients. Nebulization also needs to be carefully optimized to the breathing patterns because in the presence of nebulizer flow-peak flow mismatch, the nebulizer output is diluted by the phenomenon of air-entrainment leading to dose miscalculation.7 Air entrainment is negligible in infants, who by the virtue of their lower tidal volumes and lower flows are able to inhale pure nebulizer output.7
Inhaled medication and inhalation devices for lung disease in patients with cystic fibrosis: A European consensus
2009, Journal of Cystic FibrosisCitation Excerpt :DPIs require one or several inhalation manoeuvres which generally take about 1 min to 2 min, just as pMDIs. Using a constant output jet nebuliser, a substantial part of a nominal drug dose may be lost because of aerosols, generated during the non-inspiratory part of the respiratory cycle [140,179]. Since the introduction of the Venturi-nebulisers/breath-enhanced and breath-actuated nebulisers, drug delivery has improved considerably [141,142,168,178,193,208,209].
