Multiscale transport phenomena appear in many fields, such as fluid flows associated with nano/micro-fluidics, re-entry vehicles and vacuum techniques, and heat transfer processes in nano-scale and composite materials. It is a challenging problem for modeling and simulating such process-es due to the large spans of temporal and spatial scales as well as large range of physical scenarios. The Discrete Unified Gas Kinetic Scheme (DUGKS) is a recently developed numerical method for modeling multiscale transport process based on kinetic theory, which has the asymptotic persevering properties and is self-adaptive with the inclusion of transport physics from both continuum (diffu-sive) and free-molecular (ballistic) regimes in its algorithm development. In this talk we will report basic feature and recent progress of the DUGKS for some typical multiscale flows and heat transfer problems.
