The present study aims to elucidate the relationship between bubble behaviors in the spray sheet and internal bubbly flow of the air-induction nozzle. An experimental work was performed using the visualization technique. Effects of the air inlet position and spray pressure were investigated. The results show that compared with the bubbles inside the air-induction nozzle, bubbles in the spray sheet have smaller volume but larger average diameter. Disturbance propagates in the horizontal air-inlet segment. When the air inlet position shifts toward the nozzle outlet, overall bubble volume inside the nozzle decreases by about 56%, while in the spray sheet, the bubble volume decreases by about 77%. Bubble breakup causes a decrease in overall bubble volume as bubbles travel from the inner flow passage of the nozzle to the environment. The coalescence and compression of bubbles induce the increase in average bubble diameter. When the spray pressure increases from 0.1 to 0.3 MPa, both the total bubble volume and average bubble diameter increase.

This study addresses the significant social value of understanding consumer experiences in the coffee market, which is crucial for enhancing local economic sustainability and consumer satisfaction in the cities of Piura, Trujillo, and Chiclayo in Peru. The objective of this research was to evaluate the coffee consumption experience of 1190 consumers using structural equation modeling. Methodologically, a detailed survey was employed to capture various dimensions of consumer experience. The results revealed a strong positive effect of perceived quality on hedonic value (β = 0.776; p < 0.001), underscoring the importance of high sensory standards. Brand experiences significantly influenced quality beliefs (β = 0.399; p < 0.001) and perceived utility (β = 0.733; p < 0.001), though there was no direct connection with hedonic valuation, indicating the need for further analysis. The findings highlighted that hedonic value, associated with emotional satisfaction, predominates over utilitarian value in driving brand loyalty (β = 0.908 vs. β = 0.076; p < 0.001). This provides strategic insights into incorporating symbolic and experiential benefits in marketing. In conclusion, the study offers quantitative evidence on shaping consumer experiences in the coffee market by focusing on sensory quality and affective brand identity.
