From: One step fabrication of aligned carbon nanotubes using gas rectifier

(a) Simulated steam lines of the gas (upper) and temperature profile (lower) near the gas rectifier. The gas flow is set from left to right. (b) The z-velocity profiles plotted along the x direction at position i–v. (c) Profiles of calculated shear stress at the position i–v of the reactor. The CFD simulation was performed with the OpenFOAM software (https://www.openfoam.com/).
