Abstract: This paper has experimentally and numerically studied the windage heating in a shrouded rotorstator disk system with superimposed flow. Temperature rise in the radius direction on the rotating disk is linked to the viscous ...

Abstract: In this article a combined experimental and numerical investigation of the unsteady mixing flow of the ingestion gas and rim sealing air inside a rotating disk cavity was carried out. A new test rig was set up, and the ...

Abstract: This paper experimentally investigated a transpiration cooling performance of doublelaminated and triplelaminated sintered woven wire mesh structures with different porosities and arrangements. Each laminated test piece ...

Abstract: This paper has experimentally studied the windage torque in a rotorstator system with superimposed central inflow and rotormounted protrusions. A novel measurement method has been proposed, and the basic principle is to ...

Abstract: This article presents a further investigation on the mechanism of hot gas ingestion by exploring the ingress with complicated cavity generated by the rotormounted cylinder protrusion. During the experiment, a cavity with ...

Abstract: This paper presents a detailed investigation on the impact of protrusion parameter including both radial position and amount on the efficiency of cavity with protrusion converting additional windage loss for ingress ...
