The evaporative cooling system concepts proposed over the past century for engine thermal management in automotive applications are examined and critically reviewed. The purposes of this review are to establish the evident system shortcomings and to identify the remaining research questions that need to be addressed to enable this important technology to be adopted by vehicle manufacturers. Initially, the benefits of the evaporative cooling systems are restated in terms of the improved engine efficiency, the reduced carbon dioxide emissions and the improved fuel economy. This is followed by a historical coverage of the proposed concepts dating back to 1918. Possible evaporative cooling concepts are then classified into four distinct classes and critically reviewed. This culminates in an assessment of the available evidence to establish the reasons why no system has yet been approved for serial production commercially. Then, by systematic examination of the critical areas in evaporative cooling systems for application to automotive engine cooling, the remaining research challenges are identified

“…Currently, spray cooling have been used in a high performance computer (CRAY X-1) and is a promising solution for the thermal management of a high power insulated gate bipolar transistor (Mertens et al, 2007), laser diode laser arrays (Huddel et al, 2000) and microwave source components (Lin et al, 2004). Two examples of such applications are given in Figure 3 developed by Bar-Cohen et al (1995) and Tilton et al (1994).…”

“…The first practical application of spray evaporative cooling was reported in 1994 in an application to a computer processor [22], where miniature atomisers were used to spray a dielectric coolant. Other notable achievements in the development of spray cooling technology were the experimental studies on generating single-phase spray correlations [23][24]; the work on two-phase spray correlations [25][26][27][28]; and the spray parameter correlations (i.e.…”

A novel approach is proposed for precise control of two-phase spray evaporative cooling for thermal management of road vehicle internal combustion engines. A reduced-order plant model is first constructed by combining published spray evaporative cooling correlations with approximate governing heat transfer equations appropriate for IC engine thermal management. Control requirements are specified to allow several objectives to be met simultaneously under different load conditions. A control system is proposed and modelled in abstract form to achieve spray evaporative cooling of a gasoline engine, with simplifying assumptions made about the characteristics of the coolant pump, spray nozzle, and condenser. The system effectiveness is tested by simulation to establish its ability to meet key requirements, particularly concerned with precision control during transients resulting from rapid engine load variation. The results confirm the robustness of the proposed control strategy in accurately tracking a specified temperature profile at various constant load conditions, and also in the presence of realistic transient load variation.
