Flow Distribution Control Characteristics in Marine Gas Turbine Waste-Heat Recovery Systems. Phase I. Flow Distribution Characteristics and Control in Diffusers.
Abstract
Flow-distribution problems have become increasingly important in the design of modern fluid flow and heat transfer systems. The study of flow-distribution characteristics and control of marine gas turbine exhaust flow is the subject of this report. Major technical problems associated with nonuniform-flow distribution were reviewed and various flow-distribution control methods were evaluated. A two-dimensional, turbulent-flow model was developed for investigating flow-distribution characteristics and diffuser performance. The study was based on actual flow-distribution data from marine gas turbine exhaust flows. Results of this study indicate that a more uniformly distributed flow can be obtained by using flow-guide vanes combined with flow injection, and an improvement of approximately 20 to 36 percentage points in diffuser efficiency can be expected depending on the diffuser geometry considered.
