The data Fig_1 are the heat flux values of boiling heat transfer where qexp means the results obtained from the experiment of the present authors [13, 14], while qcalcO - the results obtained through calculations according to the original model [12] and qcalcM - the results obtained through calculations according to the modifed model. The data Fig_2 are the heat flux values of boiling heat transfer where qexp means the results obtained from the experiment as given in [11], while qcalcM - the results obtained through calculations according to the modifed model. The data Fig_3 are the heat flux values of boiling heat transfer where qexp means the results obtained from the experiment [15], while qcalcM - the results obtained through calculations according to the modified model and qcalcMP - the results obtained through calculations according to the modified model and taking into account reduced porosity
