Radiation Calculator

Welcome to the Engine Coating Radiation Calculator

This web application implements a coating/substrate two-flux heat transfer model described in the publication:

Koutsakis, G., & Clarke, D. R. (2024). Optical absorption effects in thermal radiation barrier coating materials. Surface & Coatings Technology, 487, 130974. https://doi.org/10.1016/j.surfcoat.2024.130974

This tool simulates the effects of optical absorption and scattering properties on the thermal performance of barrier coatings in high-temperature environments, such as gas turbine engines. It allows users to explore how variations in material properties influence temperature distributions and heat fluxes, aiding in the design and analysis of advanced thermal barrier coating systems.

Instructions:

Input the required material properties, gas boundary conditions, and model parameters as prompted.
Run the calculator to obtain temperature distributions and radiative heat flux results.
(Wait about a minute) and review the output to analyze the thermal performance of the coating materials.

For any issues, questions, or requests for further development, please contact: Dr. Georgios Koutsakis at koutsakis@unm.edu
