Abstract The article presents the results of a multi-factorial experiment to justify parameters rotating sprayer. Optimization pneumatic disk atomizer shows that with correct choice specific liquid flow rate (q i ), radius (r) and number radial channels ( η r ) at constant air rate, it leads obtaining required median-mass droplet diameter. Therefore, when justifying diameter sprayed drops, is n...

An olfactory display is a device to present smells. Temporal characteristics of three types displays such as one based upon high-speed switching solenoid valves, desktop-type on SAW atomizer and wearable-type were evaluated using odorants with different volatilities. The sensory test revealed that the had presentation speeds faster than valves switching. Especially, wearable an excellent tempor...
