Abstract: An evaporative spray cooling (ESC) cell was received from Rini Technologies of Oviedo, Fl. The cell was tested over the period of August-October 2009. At this time, there is no closed form expression to describe the spray cooling technique used, and it seems each individual application must be analyzed by its individual characteristics. Much was learned during the testing process, and many subsequent modifications were made to our test system. Data are presented to show this evolution, and results that were achieved at Rini Technologies are presented for comparison. Many improvements were made to our ESC test chamber, and this study will be used as a base line for comparing various cooling techniques in the future.
