Bubble dynamics during the non-isothermal degassing of liquids. Exploiting microgravity conditions

Surface water evaporation and energy components analysis during potato deep fat frying

“…After examining several possible conceptual scenarios, we propose the so-called degassing phenomenon as a reasonable physical explanation for the observed behavior. Kostoglou and Karapantsios (2007) and Divinis et al (2006) have shown that gas/vapor bubbles can form even at temperatures lower than the boiling point due to desorption of gases dissolved in potato water. Initial heating renders surface water supersaturated with respect to dissolved gases (being in equilibrium at atmospheric temperature).…”

Steady-state composition of a two-component gas bubble growing in a liquid solution: Self-similar approach

“…[16] , we can write self-similar solutions for diffusion problems, as it was previously done for the one-component case [12,21]. It has to be noted that after the pioneering works by Zener [22] and Frank [23], who used self-similar method for the description of diffusional crystal growth in the supersaturated solution, this method was exploited repeatedly by various authors for droplet growth in supersaturated vapor-gas medium [18,20,24] and for bubble growth in superheated and supersaturated solutions [8][9][10][11][12]21].…”

“…The problem of diffusional bubble growth with single gas in it was first described theoretically in the classical paper by Epstein and Plesset [7] and remains topical till nowadays when treated under different specific conditions [8][9][10][11][12][13][14].…”

“…While the discussion in Refs. [1,2,[5][6][7][8][9][10][11][12][13][14] is limited to bubbles containing only one gas, often there are two or more different gases dissolved in the solution and, therefore, presenting in the bubble. The growth of a multicomponent bubble in glass melts was described theoretically by Ramos [15] and Cable and Frade [16].…”

Effect of Liquid Properties on Heat Transfer from Miniature Heaters at Different Gravity Conditions

“…Divinis et al 2004Divinis et al , 2006Karapantsios et al 2008;Kostoglou and Karapantsios 2007). In particular, we have examined the growth of bubbles from different liquids saturated with dissolved gas when their temperature was locally raised above the saturation value, yet below their boiling temperature.…”
