We investigate the droplet size distributions and concentrations produced by an aerosol generator driven by a high velocity air jet delivered in cross flow to an oil tube at Mach numbers of 0.1-1.0, and Weber numbers based on the air flow parameters between 1000 to 40000. Measured Sauter mean droplet diameters (SMD) from 1μm to 3.5μm were determined by an Electronic Low Pressure Impactor over t...

Spreading dynamics of liquid droplets impacting onto powder bed are experimentally studied using high-speed photography. Dimensionless numbers— We , Re the modified * and ∗ corrected by substrate deformation—are used to analyze impact behaviors droplets. The spreading time maximum factor further analyzed. is accurately described a universal scaling law that obtained from dimensionless vs. effec...

O escopo do presente trabalho é investigar as conexões interdisciplinares entre a Neurociência, História da Matemática e Música. Serão discutidos avanços como Lei de Weber-Fechner, sistemas representação valores numéricos, com enfase no (ANS-Approximate Number System) frações seão representações inatas não simbólicas magnitudes analógicas. Com base nesses avanços, serão analisadas quais escalas...
