“…The main driving mechanism in spray cooling is the thin film, which is created just above the cooled surface (Chen, 2002). In a single pressure atomized spray nozzle the liquid run off which is about 90% of the input is pushed away from the cooled surface via the momentum of the spray (Figure 4.1), the other 10% is evaporated away (Chen 1995).…”

“…The sixteen spray nozzles were distributed evenly so that their spray cones covered a square area of 16.8 cm 2 , this roughly give a cooled area of 1cm 2 for a single nozzle. The selected spray nozzles are were 1/8GG-FullJet 1 from spray systems co and were selected based on their even spray distribution and higher droplet velocities (Chen, 2002).…”

“…In recent years, numerous investigations have been performed on the parameters that influence spray cooling performance. Chen et al [4], [5] experimentally studied the effects of spray parameters (mean droplet size, droplet flux, and droplet velocity) on critical heat flux (CHF) and the heat transfer characteristics. The results showed that the mean droplet velocity (V) had the most dominant effect on CHF and the heat transfer coefficient, followed by the mean droplet flux (N).…”

An experimental investigation was performed to study the effects of the spray coverage area, the film area, and the impact droplet velocity on the thermal performance of a spray cooling system. All experiments were carried out in a closed loop spray cooling system working with deionized water as a cooling medium. A plain copper surface with a diameter of 15 mm was used as a target surface and tested in the single-phase and twophase regimes. The coolant mass flux was 15.5 kg/s.m 2 , and the distance between the nozzle and the heated surface was varied from 10 to16 mm. Due to the change in the nozzle height, the spray coverage area, the film area, and the droplet impact velocity were changed and affected the thermal performance of the spray cooling system. As a sequence of these changes, the experimental results showed that these parameters have a significant effect on the heat transfer characteristics.

“…Several experimental and theoretical studies on liquid jet impingement heat transfer have been reported in the literature (Louahlia & Baonga, 2008, Chen et al, 2002, Lin & Ponnappan, 2004, Liu & Zhu, 2004, Pan & Webb, 1995. Numerous studies are conducted in average heat transfer, but local heat transfer analysis for steady and unsteady states has not been much attention.…”
