Abstract：Two-dimensional event-driven simulations are employed to gain insight into the granular energy and segregation in granular gases with a Gaussian particle size distribution when exposed to a differential heating mechanism. It is found that the bulk value of the temperature ratio depends on the choice of differential boundary heating, while the segregation behavior is insensitive to the differential heating mechanism. Moreover, by studying the numerical model without spatial degrees of freedom, differential boundary heating is found to affect nonequipartition in the bulk of the system even where heating events are rare compared to collisions.
