Thermal Distribution on Gas Turbine
Blade Using Thermal Paint
P. L. Rupesh and Arulprakasajothi
Abstract Thermal life of any hot surface depends on its surface temperature
measurement. Turbines and combustors are the main components of a gas turbine
system which are subjected to high thermal stress due to flow of combustible gases.
Higher exposure of these components to the maximum temperature leads to thermal
stress; hence, the measurement of temperature at different locations of these components is necessary. Measurement of temperature through thermal paints is the latest
development in the field of surface temperature detection. The present study deals
with the design, fabrication and surface temperature evaluation of gas turbine blades.
The colour change observed at different locations of blades corresponds to different
temperature. A computational analysis of these blades has been performed. The
observed experimental results hold in good agreement with the computational results.

1 Introduction
Gas turbine is a power plant, which creates a lot of vitality for its size and weight. The
gas turbine has discovered expanding administration in the previous 40 years in the
power production. Its smallness, low weight and numerous fuel applications make
it a characteristic power plant for seaward stages [1]. Today, there are gas turbines,
which run on petroleum gas, diesel fuel, naphtha, methane and biomass gas. Gas
turbine motor progressed as a fundamental part and the most capable driving force
unit for aircrafts. It is directly used in for all intents and purposes the whole of the
voyager flying machines worldwide with different assortments [2].
