Centrifugal Fan optimal operating speed

Hi everyone,

Recently I have designed a small centrifugal blower (impeller + volute scroll). I was wondering if there is a sugested approach for finding its optimal rotation speed

using Flow Simulation.

Almost all industrial fan systems, come with a suggested speed RPM operating point. So how can I find what is the optimal speed for my newly designed fan?

I would welcome any thoughts or suggestions

Best Regards
