Evaluation Of Velocity Variation In A Chute As A Function Of Roughness. Abstract: The present paper establishes numerical simulations with CFD packages for analyze the velocity variation as a function of roughness in a chute, and to determine the use of OpenFOAM® CFD package for this phenomenon. Experimental data was obtained from a physical hydraulic model with a smooth bottom and was compared with the results of numerical simulations from the CFD packages: ANSYS®, FLOW-3D® and OpenFOAM®. Subsequently, the roughness at the channel bottom was increased and new simulations were carried out for define the new velocity values. Increases in the resistance coefficient resulted in a significant reduction in velocity and the results of free open source OpenFOAM® are similar to those obtained in physical modeling as well as commercial software
