Gas‐liquid direct‐contact evaporators are characterized by the bubbling of a superheated
gas through the solution to be concentrated. In other words, they are nonisothermal bubble …

Slug flow is a dynamically complex two-phase flow pattern. A wide variety of industrial gas-
liquid systems operate under slug flow conditions for not only flow transportation purposes …

Until recently, generating clouds of microbubbles was a relatively expensive proposition,
with the smallest bubbles requiring high energy density from either the saturation …

Experimental bubble size distributions and bubble mean diameters were obtained by means
of a photographic technique for a direct-contact evaporator operating in the quasi-steady …

An experimental study concerning the influence of liquid temperature on bubble
coalescence is presented. Bubble collisions in two different liquids (water and ethanol) were …

The submerged combustion evaporation process, which is extensively utilized in the
treatment of high salinity wastewater, inevitably confronts the challenge of particle …

A computational model of a single gas microbubble immersed in a liquid of ethanol–water
mixture is developed and solved numerically. This complements earlier binary distillation …

Using the air–water system, transient experimental measurements of liquid temperature,
bubbling height, evaporation rate, gas hold-up and bubble size distributions in a direct …

The purpose of this study is to analytically assess the local heat transfer coefficients by using
the local bubble properties, which include the local gas holdup, bubble pass frequency …

Heat transfer continues to be a major field of interest to engineering and scientific
researchers, as well as designers, developers, and manufacturers. The wealth of …
