Abstract
In this work, a numerical and experimental investigation have been performed about the influence in the tonal noise-pressure level at the blade pass frequency of the additional components that are placed downstream a centrifugal blower in a refrigeration system of an induction cooktop. Four scenarios have been analysed by means of computational fluid dynamic software, evaluating the variation of pressure in time at the volute-tongue area and the results have been compared in a qualitative manner with the experimental acoustic measurements.
