Evaporative Mist Cooling as Heat Dissipation Technique: Experimental Assessment and Modelling

The severity of extreme weather conditions brought on by climate change are conditioning quality of life, economic development, and well-being in today’s cities. Conventional measures have been shown to be insu cient for tackling climate change and must be supplemented with ecofriendly approaches. H...
