Abstract
This paper investigates the effect of cavity width on effectiveness Θ and total pressure losses ζ of pre-swirl systems. Computations are performed for the flow parameter 0.375 <λТ < 0.75 , rotational Reynolds number1.69⋅107 < ReФ < 2.33⋅107, throughflow Reynolds number or non-dimensional mass flow rate 2.79 ⋅105 < Cw < 5.73 ⋅105 and swirl ratio 0.548 < β < 2.5 . No influence on Θ and ζ is found by changing the cavity width.
