“…The results showed the average absolute deviation of the correlation in the inspection database 4.4%. The correlation has a wide application range and can be applied to various channel sizes and different fluids [17][18][19]. Kim and Mudawar constructed a new correlation by superimposing the effects of nucleate boiling and convective heat transfer.…”

Subcooled boiling is the most effective form of heat exchange in the water jacket of the cylinder head. Chen's model is the most widely used correlation for predicting boiling heat transfer, but the selection of the correlation for the nucleate boiling is controversial. The work of this paper is to simulate the heat transfer process in the water jacket of the cylinder head with a horizontal rectangular channel that is heated on one side. Using the coolant flow velocity, inlet temperature and system pressure as variables, the heat flux and heat transfer coefficient were obtained. The results show that the increase of the coolant flow velocity can effectively promote the convection heat transfer, and the change of inlet temperature and system pressure will affect the occurrence of nucleate boiling. However, the Chen?s model predictions doesn?t fit well with the experimental data. Four nucleate boiling correlations were selected to replace Chen's model nucleate boiling correlation. The correlation proposed by Pioro coincides best with the experimental data. The mean error after correction is 18.2%.

“…These data were collected by the same authors in a small diameter tube (1.1 mm) at relatively high saturation temperatures (31°C and 41°C). Finally, the model by Fang et al [26] was included. This equation is fitted on a very large database, including R600a data of Yang et al [4] and the R152a data of Hamdar et al [7].…”

“…This equation is fitted on a very large database, including R600a data of Yang et al [4] and the R152a data of Hamdar et al [7]. Fang and his group, in their review [1] tested several models and found that the Fang et al [26] equation used for R134a, R600a and R152a outperformed any other equation considered by them. It is worth to underline that they included, among others, all the models considered in the present paper with the only exceptions of Sempertegui Tapia and Ribatski [6] and Oh and Son [25] models.…”

R134a was recognized as probably one of the most important refrigerants of the two past decades. Among the proposed alternative fluids, there are certainly isobutane (R600a) and R152a. This article presents about 200 new heat transfer coefficient and pressure drop data obtained during flow boiling of R152a and R600a inside a smooth copper tube having an internal diameter of 4 mm. Three saturation temperatures were considered for each refrigerant, from 5 °C to 20 °C. Furthermore, for each temperature studied, the heat flux was varied between 15 and 30 kW m−2 and the refrigerant mass flux from 100 to 400 kg m−2 s−1. After presenting the new data, a critical comparison was proposed between the performance of these refrigerants and R134a. Finally, some classic correlations available in the literature have been implemented. The deviations between the calculated and experimental values were reported and commented.

“…It is mainly composed of boiling in mini-and micro-scale (or other compact heat exchangers) (Saisorn and Wongwises, 2012;Cheng, 2016), critical heat flux (Ong and Thome, 2011;Fang et al, 2015;Konishi and Mudawar, 2015), microgravity (Kattan et al, 1998b;Zhang et al, 2016e) and nuclear phenomena (Santini et al, 2016;Gou et al, 2017). Since the work of Steiner and Taborek (1992), only recent heat transfer correlations that are deduced for water flow boiling in conventional diameter tubes and channels (hydraulic diameters larger than 3 mm Kandlikar and Grande (2003) are proposed by Shen et al (2016), Fang et al (2017), andShah (2017).…”

“…Moreover, the Shen et al (2016) correlation is only valid for vertical tubes and for a narrow data range. Although, the Fang et al (2017) and the Shah (2017) correlations claim to cover water flow boiling heat transfer in conventional size tubes and channels, none of the three correlations have been experimentally validated for saturated flow boiling heat transfer of water in smooth tubes.…”
