FLOW SIMULATIONS ON ALL SPEED REGIMES USING MULTIBLOCK GRIDS
(SIMULAÇÕES DE ESCOAMENTO EM QUALQUER REGIME DE VELOCIDADE UTILIZANDO MALHAS MULTIBLOCO)

Summary :
|
|
THE SOLUTION OF INTERNAL FLOWS IN GEOMETRICALLY COMPLEX CONFIGURATIONS IS ADDRESSED IN THE CONTEXT OF STRUCTURED MULTIBLOCK GRIDS USING A MODIFIED VERSION OF THE BEAM AND WARMING ALGORITHM TOGETHER WITH A CONVERGENCE ACCELERATION METHOD. THE FLOWFIELDS OF INTEREST WERE ASSUMED TO BE ADEQUATELY MODELED BY THE 2-D EULER EQUATIONS. THE WORK PRESENTS FLOW SIMULATIONS OVER SIMPLE CONFIGURATIONS WHICH SERVE THE PURPOSE OF VALIDATING THE PROPOSED METHODOLOGY. RESULTS ARE COMPARED TO DATA FROM THE LITERATURE AND DEMONSTRATE THAT THE CAPABILITY IS READY TO HANDLE TRULY COMPLEX CONFIGURATIONS.
KEYWORDS: MULTIBLOCK ALGORITHMS, COMPUTATIONAL AERODYNAMICS, APPLIED NUMERICAL METHODS, FLUID MECHANICS, COMPLEX CONFIGURATIONS.
