Abstract
Purpose
This paper aims to validate an axial turbine modified nozzle design, looking for a reduction of the nozzle erosion process during operation in power plants.
Design/methodology/approach
The approach taken is numerical simulation using the computational fluid dynamics (CFD) tool, comparing original and proposed/modified nozzle designs.
Findings
The paper provides information about how to achieve a solution of the turbine operational problem (abrasive wear) by an analysis of flow patterns under a variety of conditions.
Research limitations/implications
It does not give a detailed interpretation of flow behaviour due to the lack of validation data.
Practical implications
A very useful flow simulation methodology that can be used in industry is provided.
Originality/value
The proposed design modification of an axial turbine nozzle with the aid of CFD simulation has not been performed yet. This paper investigates the possibility of nozzle erosion reduction by modifying local flow patterns.
