This paper presents numerical simulations of the laminar flow of lubricating greases in a channel with rectangular cross section. Three greases with different consistencies (NLGI grades 00, 1 and 2 respectively) have been considered in three different configurations comprised by a rectangular channel without restrictions, one rectangular step restriction, and one double lip restriction. The driving pressure drop over the channel spans from 30 kPa to 250 kPa. The grease rheology is described by the Herschel-Bulkley rheology model, and both the numerical code and rheology model have been validated with analytical solutions and flow measurements using micro Particle Image Velocimetry.
