USING SUSPENDED MOISTURE FOR COOLING HIGH-TEMPERATURE GAS TURBINES,
Abstract
The study discusses cooling of high temperature turbines by introducing suspended water vapor. The cooling considered to date can be divided into four different methods. In methods I and II, the suspended water vapor is fed directly into the gas flow channel. In method I, water is injected directly into the gas flow. The water diffusion process can be mechanical or pneumatic. In method II, only a portion of the moistened cooling flow is injected into the dynamic section of the turbine. In method III, the suspended water vapor is used for cooling the blade radiator by employing a double flow cooling system. In Method IV, the blades are cooled by a single flow saturated with suspended water vapor. Recently, systematic experimental studies were conducted on cascade heat exchangers and cylindrical rods over a wide range of dimensions and gas dynamic characteristics of two-phase flows. Finned cascade heat exchangers were also investigated. The plotted data are shown. (Author)
