Abstract
The review article emphasizes a single technique: Spray cooling, which
is essential in diverse fields from laser treatments to humidifiers.
Thus, proving its significance in modern-day research by proving it to
be a perfect alternate solution as a cooling technique. The article
thoroughly details single and multi-phase cooling with detailed insight
into its architectural aspect, classification, and design. The article
further emphasizes modeling heat transfer dynamics with a few attempts
from simulations. It highlights the general mechanism of heat exchange
involving arguments from the droplet level, impacted by successive
generations of droplets, and the evolving thermal footprint of a hot
surface to visualize cooling. Furthermore, an attempt to list out the
factors involved in spray cooling, such as the nozzle characteristics,
surface texture, flow rate, and spraying combinations have been
discussed in detail. The later parts of the paper deal with the
fundamental challenges related to the conduction of electricity, power
consumption, efficient packing, corrosion, flooding, and suitable
suggestions to overcome the mentioned problems. In the final part, a new
enhancement has been suggested by the authors, which could, in theory,
be the subsequent developmental work in spray cooling. The paper also
includes summary tables relevant to the heading concepts to enhance,
deepen, and help in the thorough understanding of the concepts.
