Interface Stability between Two Gas Streams of Different Density in a Curved Flow
Abstract
More severe temperature conditions require novel cooling methods for small turbines. A concept applicable to small turbines is described. It involves co-flowing streams within the turbine blade passage: one cold and one hot. This concept, referred to as the Radiax Turbine, provides for strong blade cooling even in very small turbines where traditional cooling approaches cannot be used. However, fundamental studies of turbulent flow in curved channels of two streams of different total pressure and temperature are required to provide the basic information needed in understanding this co-flowing streams in a curved channel. This report covers the design of an experimental apparatus that will be used for investigating the interface stability between two gas streams of different densities in a curved flow and reports on flow visualization studies performed with the apparatus. Several types of instability are possible in these curved mixing layers and they are discussed in the report.
