抄録

<p>In this paper, the rewritten boiling model is embedded into Fluent in the form of UDF to perform numerical calculation of low-pressure boiling. In order to ensure the correctness of the rewritten boiling model, this paper uses the experimental data of Lee experiment to verify the correctness of the rewritten boiling model. The results show that the rewritten boiling model agrees well with the experiment. In addition, this paper only uses Fluent to carry out the numerical simulation of Lee's experiment, but has never obtained a numerical solution. Therefore, using UDF to rewrite the boiling model can improve the convergence of Fluent when calculating low-pressure boiling.</p>
