CEP: September 2017 Coupling the traditional computational fluid dynamics (CFD) approach to model the fluid phase with the discrete element method (DEM) to model the particles creates a powerful numerical method to study multiphase particulate flows. See how CFD-DEM can be applied to modeling gas-solid multiphase systems. Other topics in this issue include human factors in alarm response, back to basics: boilers, and troubleshooting wastewater treatment. Editorial CEP on the Go Last month I wrote about some of the personal benefits of volunteering — such as better emotional and physical health, a lower risk of cognitive impairment as you age, and a perception of having more time on your hands — as well as the positive impacts volunteering can have on your career. And last month’s Your AIChE Benefits article (Aug. 2017, p. 75) explained the concept of micro-volunteering — i.e., quick, easy tasks that do not require a large investment of time.
