description: This paper is devoted to the study of the turbulence models influence on the numerical simulation of flow and heat transfer in a channel with one-sided ribbing. Tasks that were solved during the study: â¢ analyze the sensitivity of the grid on simulation results; â¢ to investigate the effect of the applied turbulence model on the flow and heat exchange in the ribbed channel; â¢ comparison of the numerical simulation with the experimental and simulation literature data; â¢ to evaluate the effect of the rib pitch on the wall heat transfer intensification. The ANSYS Fluent v2021 software package was used for numerical simulation of flow and heat transfer. Modeling were carried out using seven turbulence models for two Reynolds number equal to 13100 and 37200. A parametric study of effect of the distance between the ribs on the flow and heat transfer in the channel was carried out. As a result, it was revealed that the k-Ï BSL model gives the distribution of the Nusselt number closest to experimental data. Reynolds stress models give inaccurate results for 2D formulation. And it was also found that the intensification of heat exchange monotonically increases with an increase in the ribbing pitch.
