Abstract
Venturi-type devices can vary from minor adjustments in their geometry to more complex engineering adaptations, depending on their industrial application: automotive, food, agricultural, oil, among others. Thus, their study still becomes necessary nowadays. And the computational modeling aggregates as an important additional tool for investigation and determination of flow variables as the pressure recovery, that affect stability and performance in the processes that apply the Venturi principle. Therefore, this numerical study aims to analyze the flow pressure recovery in Venturi-type devices. In this analysis, flows turbulent, incompressible, and isothermal were assumed. The governing equations involved are the Reynolds-averaged Navier–Stokes equations. Three types of k–epsilon models were employed to solve the turbulence. One commercial software for computational fluid dynamics, which uses a finite volume method in the discretization of the governing equations, was used to obtain the solutions. The simulations’ results were compared to experimental data for the pressure and showed a satisfactory concordancy, aiming to demonstrate the applicability of the computational model developed.
