A comprehensive study on the influence of resolving an injector orifice and the influence of creating stripped off droplets on spray formation using the VSB2 spray model
Journal article, 2020

With respect to simulating fuel sprays applied to direct injection engines, few
studies in literature have investigated resolving the injector orifice and how this
may influence spray predictions for high pressure and temperature diesel engine
like conditions. In this work, we used the Stochastic Blob and Bubble (VSB2)
spray model to conduct simulations in which fuel is injected into a constant
volume combustion vessel. The injector orifice is resolved into 9 cells. The
boundary conditions were the same as the Engine Combustion Network (ECN)
non-combusting case for n-dodecane (ECN, 2020).
