In the pursuit of sustainable cooling solutions, passive techniques have gained significant attention for their ability to reduce energy consumption in indoor and outdoor applications. Adiabatic cooling efficiently lowers air temperatures through water evaporation. The success of such a technique depends heavily on the ability of the air jet to disperse the droplets in the target volume. To improve droplet dispersion, it is necessary to enhance the entrainment capacity of the carrier air jet. This study investigates for the first-time flow entrainment intensification using lobes as vortex generators into a multi-jet diffuser for adiabatic cooling application. A multi-lobed jet diffuser consists of a tube pierced with a series of lobed orifices each is a daisy shaped orifice on a hemisphere (DOH). Such a geometry is intended to offer promising potential for improving overall performance in cooling applications compared to the convention-al multi-round jet diffuser (ROH). As a first step, before integrating water evaporation, it is essential to understand airflow dynamics under monophasic conditions. Experiments were conducted in a climatic chamber, providing precise control over temperature and airflow conditions to investigate the jet behavior by employing Particle Image Velocimetry and fast visualization techniques. The results indicate that DOH multi-jet flow expands more than traditional ROH multi-jet flow under the tested conditions. Specifically, in the minor plane, the dynamic jet widths Y0.5 and Y0.1 for DOH were 10% and 15% wider, respectively, and in the major plane, they were 12% and 13% wider supporting their superior mixing potential. These results suggest that integrating multi-lobed jets into evaporative cooling applications could enhance droplets dispersion into the target air volume.
