چکیده
An experimental study focuses on the airborne sound generated during bubble bursting at surface of a liquid bath. It is found that acoustic frequency drifts and increases, consistent with Helmholtz-type resonance cavity being more opened as thin film in air retracts. As an extension, simple model based collection drifting Helmholtz resonators proposed, capturing main features fizzing effervescing beverage.

Effervescence in a glass of champagne: A bubble story
People have long been fascinated by bubbles and foams dynamics, and since the pioneer work of Leonardo da Vinci in the early 16th century, this subject has generated a huge bibliography. However, only very recently, much interest was devoted to bubbles in champagne wines [1]. Small bubbles rising through the liquid, as well as a bubble ring (the so-called collar) at the periphery of a flute pou...
متن کاملDesign of Fast Disintegrating Tablets of Prochlorperazine Maleate by Effervescence Method
In the present work, fast disintegrating tablets of prochlorperazine maleate were designed with a view to enhance patient compliance by effervescent method. In this method, mixtures of sodium bicarbonate and anhydrous citric acid in different ratios along with crospovidone (2-10% w/w), croscarmellose sodium (2-10% w/w) were used as superdisintegrants. Estimation of prochlorperazine maleate in t...
متن کاملNovel levocetirizine HCl tablets with enhanced palatability: synergistic effect of combining taste modifiers and effervescence technique
OBJECTIVES Levocetirizine HCl, a second-generation piperazine derivative and H1-selective antihistaminic agent, possesses few side effects. The first objective of the study was to compare and evaluate the taste-masking effect of different ratios of 2-hydroxypropyl-β-cyclodextrin and mannitol on levocetirizine HCl using an inclusion complex and solid dispersion, respectively. The second objectiv...
