“…Recently, Peyghambarzadeh et al [15] studied pool boiling heat transfer to binary and ternary hydrocarbon mixtures and proved that Schlünder correlation [5] is the most accurate correlation for estimating the nucleate pool boiling heat transfer coefficient of binary mixtures. The Schlünder [5] correlation, which is shown as Eq.…”

“…Alavi Fazel et al [14] have compared the predicting correlations for binary mixtures and have reported the absolute average deviation of each of them without pointing to any particular used thermodynamic model. In this regard, Peyghambarzadeh et al [15] categorized almost all of the correlations for the prediction of pool boiling heat transfer coefficient of binary mixtures and demonstrated that Schlünder [5] correlation in comparison with other existing correlations predicts the heat transfer coefficient more accurately. Sarafraz et al [16] performed an experimental study to measure the pool boiling heat transfer coefficient of binary dilute mixtures of water/glycerol, water/MEG (mono-ethylene glycol) and water/ DEG (di-ethylene glycol) around the horizontal cylinder.…”

“…Most of earlier correlations' bodies are consisted of physical properties [18][19][20][21][22]. To estimate the physical properties, for each property, a large number of accurate correlations with uncertainty lower than 10% were separated from other existed correlations in well-known handbooks [26][27][28].…”

Nucleate pool boiling heat transfer coefficients were measured during pool boiling of the mixtures of Citric acid/water on a horizontal heated Cylinder. The experiment was done at atmospheric pressure and heat fluxes up to 113 kW m -2 and mass fraction range 0.1496-0.613 over all ranges of mass fraction, the heat transfer coefficients of the mixtures are markedly less than those in single component substances and, in particular, are dramatically deteriorated in the vicinity of both single component substances. An applicability of existing correlations to the present experimental data is discussed. As a result, it is difficult for any existing correlation to predict the true values of pool boiling heat transfer coefficients over all ranges of mass fraction in mixtures of citric acid/water. Available correlation results were not exactly adapted to experimental data and for the best estimation, a new modified model based on Stephan-Kroner has been achieved with reasonable accuracy. Also the status of bubble generation showed that nucleation site density is strictly functioning of heat flux.

“…Several works have related this decrease in the mixture HTC to phase-equilibrium parameters such as the boiling range (the difference between the dew-point and bubblepoint temperatures) and the compositions of the vapor and liquid phases [10,12,28,44]. Consequently, most HTC mixture correlations consider at least one of these phase-equilibrium parameters in the calculation.…”

Many correlations to estimate the heat transfer coefficient (HTC) in nucleate boiling with binary, ternary or multicomponent mixtures are available in the literature. These correlations are usually based on phase-equilibrium parameters. Direct calculation of the HTC in mixtures with hundreds of components, such as gasoline, is thus practically impossible, as the phaseequilibrium data for such mixtures cannot be easily obtained or calculated. In research fields such as droplet evaporation and mixture thermodynamics, surrogates are constantly used to replace these multicomponent mixtures in calculations; however, this method has not yet been used in boiling research. Here, gasoline surrogates are proposed to estimate the HTC during nucleate boiling. A Monte Carlo search for the optimal composition is used to find the surrogates, and their applicability to gasoline-ethanol blends is evaluated. Two of the surrogates tested matched the experimental data well: surrogate B (16.4% n-butane + 83.6% isooctane) and surrogate C (26.2% n-butane + 42.1% n-hexane + 31.7% isooctane). Both surrogates allowed the HTC for gasoline (3.6% and 3.5% overall average deviation, respectively) and gasoline-ethanol blends (5.6% and 6.9% deviation at 400 kW/m 2 heat flux, respectively) to be estimated accurately.
