We determine a constitutive equation for developed three-dimensional granular flows based on series of discrete element method simulations. In order to capture non-local phenomena, normal stress differences, and secondary flows, we extend previously proposed temperature-sensitive rheological model by considering Rivlin-Ericksen tensors up second order. Three parameters are calibrated with the i...

turbulent fluxes in the atmospheric boundary layer are calculated using different models. one of the most popular and operational models in this groundwork is the second order turbulent model of mellor and yamada that has been widely used to simulate the planetary boundary layer (pbl). despite its popularity, it has been shown that this model has several weeknesses that affect its accuracy. the...
