”The global population is project to grow from 7 billion today to 9 billion by 2050. The in-crease in population and the accompanying shifting global economic patterns will result ina significant increase in demand for food, energy and protection. Separation technologyplays a key role in ensuring new solutions are environmentally sustainable. Indeed, existingseparation technology has enabled us today to have clean air and water. Nearly every pro-duction process in today’s society requires a separation step. As a result, global market inseparation technology is growing and is over USD 100 billion annually. Exactly how shouldseparation research develop in the next decade and beyond? Nowadays technical solutions areavailable for almost every separation task. However for the future the pressing challenge isto find economical solutions. If the ideal separation technology/process would have been in -vented, our world would face fewer difficulties for food, water, energy and environment… ”

We will measure the solids fraction of the cellulosic support media, then generate the domain of the cellulosic media using polygon simulations of its fiber cross-sections. CFD runs under zero-slip conditions for the cellulosic media will allow us to compare its pressure drop and particle capture combined with the nanofiber web to measured values of the composite media. These simulations will be run for a range of velocities, to test the reliability of the models and CFD calculations at different operating conditions. Conclusions While this study is incomplete, it points to ways to simulate nanofiber additions to filter media, when the nanofibers exist as a single-layer web of interconnected cylindrical elements. We have also developed means to generate fiber cross-sections and size distributions which closely mimic the appearance of SEM images of the cross-sections of actual cellulosic media. CFD runs calculating the pressure drop across the simulated nanofiber web geometry show that the pressure drop across the nanofiber web is a small percentage of the composite media pressure drop.
