... box truck lift drag vortex wake flow separation Abstract The aerodynamic performance of medium-duty box trucks significantly impacts fuel economy and environmental sustainability. However, research on their aerodynamics has been limited compared to heavier trucks. This study uses...

... boxy car lift drag vortex wake flow separation Abstract This study investigates the aerodynamic qualities of a sub-compact car with a boxy shape using a two-dimensional (2D) model. The research examines the flow over the vehicle and the lift and drag forces that can affect fuel...

... of the models can predict the general flow behavior while exhibiting their advantages. A better agreement with the experimental data is obtained when the turbulent Schmidt number is gradually decreased. However, examining the critical characteristics like upstream flow separation, bow shock prediction, and mass...

... the simulation techniques which will be used for future jet simulations, in which shock wave locations and orientations are important, such as jet impingement on a flat plate and particle-shock interactions. Keywords: CFD, High Reynolds number jets, Flow visualization, Flow separation, Cold spray, Supersonic...

.... The computational model for the study utilizes finest hexahedral grids. A commercial CFD package ANSYS® CFX 11.0 was used with standard k -ω turbulence model for the simulations. CFD results were well validated with experiments. The following observations were made: At higher stagger angles, flow separates from...

... Micro-mixing Dean vortices Flow separation Chaotic advection μPIV Mixing characteristics in a 2D serpentine micro-channel were studied experimentally to understand the role of Dean vortices in enhancing mixing. Mixing plane deformation was visualized at Reynolds numbers ranging from 1...
