文摘

An quasi-dimensional multi-component vaporization model for wall film was developed. The thermal and mass diffusion in the film was described by high-order polynomials. Effect of the thermal and mass diffusion on diesel film vaporization was discussed. The relative error of various vaporization models for wall film was discussed. Computational accuracy and efficiency of models were evaluated in CFD application.
