The fine dust particles entering turbine blades are easy to deposit and weaken the heat transfer performance of the internal cooling channels. In order to explore the deposition characteristics of fine dust particles in the cooling channel inside the blade, the effects of fine dust particle diameter and Reynolds number of cooling air on the deposition of fine dust particles were experimentally studied. The experimental results showed that the deposition rate of the internal cooling channel increased firstly and then decreased with the Reynolds number of the cooling air. When the Reynolds number was up to
