The invention relates to a method of determining characteristics of orifices (O, . . . , O) to be made through a plate () positioned in a circuit () across the fluid passage. Said method comprises defining fluid data, the number of orifices, and for each orifice a control segment or area. The fluid flow rate through each orifice of the perforated plate is calculated, and for each orifice, the flow rate density is calculated by dividing said fluid flow rate by the associated control segment length or control area. The optimized or non-optimized nature of the orifice characteristic is determined by comparing said flow rate density with the mean flow rate density. If the difference in absolute value lies within a predetermined range of values, then the orifice characteristics are considered as being optimized. Otherwise at least one characteristic of at least some of the orifices is modified.
