“…Flashing spray is a process of rapidly injecting a high-pressure working fluid into a low-pressure environment to make the liquid in an overheated state and then explosively atomizing it to produce small droplets . As an efficient cooling method, this technique has been widely applied in many industrial fields, such as water desalination, binary ice production, skin protection during dermatologic laser surgery, and superheated water jets . Besides, the technique also solves the extreme heat dissipation of ultrahigh-power devices. , As the basis of spray, a single droplet is a simple alternative method to study spray.…”

Isobutane alkylation catalyzed by a composite ionic liquid is a new technology for the production of clean gasoline blending components. In this process, efficient effluent cooling plays a crucial role in energy conservation. A new cooling application by effluent (mainly isobutane) evaporation was proposed for this target, in which the effluent was released into a low-pressure environment to enhance and control the evaporation of isobutane. The transient temperature of isobutane droplets was measured by suspending them on the tip of a thermocouple while a high-speed camera recorded the evaporation process. The effects of final pressures, different initial droplet diameters, initial droplet temperatures, and gas concentrations of isobutane on evaporation behavior and droplet temperature were investigated. The results demonstrated that isobutane droplets underwent intense evaporation and stable evaporation phases. The evaporation rate constant (k 0 ) exhibited a linear increase with decreasing final pressure and increasing initial droplet diameter. With the decrease in k 0 , the droplet evaporated in three states: expansion and breaking, only expanding but not disintegrating, and surface evaporation. The evaporation rate constant (k 1 ) during the stable evaporation phase was influenced by the initial droplet diameter and the concentration gradient between the droplet and the environment due to the concentration difference around the droplet. The lower the final pressure, the lower the droplet temperature in the stable evaporation stage, and the droplet diameter and initial temperature did not appear to affect the droplet equilibrium temperature. Adjusting the final pressure allows for precise control of the temperature of the droplets during the stabilization phase of evaporation.

The energy consumption for cooling takes up 50% of all the consumed final energy in Europe, which still highly depends on the utilization of fossil fuels. Thus, it is required to propose and develop new technologies for cooling driven by renewable energy. Also, thermal energy storage is an emerging technology to relocate intermittent low-grade heat source, like solar thermal energy and industrial waste heat as well as to exploit off-peak electricity, for cooling applications. This review aims to summarize the recent advances in thermally driven cooling and cold storage technologies, focusing on the formation and fabrication of adopted composites materials, including sorption materials, phase change materials, and slurries. Herein, first the classifications, selection criteria, and properties for these three types of materials is discussed. Then, the application potentials of all the materials are prospected in terms of economic analysis and sustainability.
