2. Summary

 

This study analyses big data of hollow fiber direct contact membrane distillation (HFDCMD) for simulation-based empirical analysis. The self-organizing map(SOM) and multiple linear regression(MLR) methods are used to statistically analyze the big data such as physical and dimensionless data. In the SOM analysis, the mass and heat fluxes are represented as the membrane Peclet and Nusselt numbers, dimensionless numbers, respectively.

And in the MLR analysis, macroscopic parameters such as temperature and radii of lumen and shell sides mostly controlled the MD performance. Also, reduced shell temperature and effective porosity have the highest beta value for mass and hear fluxes, respectively.

Through this study, the authors want to say there are fundamental revisions to include not only fluid- and thermo-dynamic effects but also temperature-dependent fluid properties.

 

 

3. Originality & Creativity 

This study used the big data analysis such as SOM and MLR to find correlation between physical and dimensionless data and performance of MD.
