Labyrinth seals (LSs) in turbomachinery are used to minimize leaks. This study presents an experimental setup designed to test and validate LS designs. The test bench (TB) described in this paper can evaluate different LS designs obtained through various methods to find better solutions to mitigate greenhouse gas (GHG) emissions. Prototypes with co...
The incompressibility hypothesis is successfully applied in a broad range of engineering problems simulated via computational fluid dynamics (CFD) codes. However, depending on the Mach number, the effects of compressibility are no longer negligible. Recently, the first papers about topology optimization considering compressible flows were published...
The present work aimed at numerical simulation of a two-dimensional, incompressible and steady-state airflow over a NACA0015 airfoil with flap and Gurney flap using the standard turbulence models k-epsilon, k-omega and versions of these models with modified constants. All meshes used were structured. Comparison of the results of the turbulence mode...
A quasi-one-dimensional (1D) mathematical model coupled with Computational Fluid Dynamics (CFD) simulations of a water ejector is presented. Using data from CFD simulations, the mathematical model was used to calculate the friction loss coefficients of the ejector components, to predict its maximum efficiency point and to delimit its envelope of op...
Ressumo. Neste artigo propoe-se um modelo físico-matemático para o escoamento viscoso e paralelo ao redor de um corpo rombudo arbitrário. A partir da formulação estacionaria para as equações de Navier-Stokes, função de corrente-vorticidade no plano, calcula-se uma solução exacta para o escoamento paralelo que depende do número de Reynolds e de um p...
