FY17 GRC: Tuna-Inspired Heat Pipe for High OPR Gas Turbines

Metadata Updated: February 28, 2019

This project aims to explore[HTML_REMOVED]high OPR ([HTML_REMOVED]60) Turbofan engines and HGEP (Hybrid Gas-Electric Propulsion) using counter-flow heat-pipe airfoils (including oscillating heat pipes) with nanofluids as the working fluid instead of alkali metals and by using fuel and the bypass stream as heat sinks. This is a novel concept with strong industry interest. Industry studies have shown that conventional turbofan engine architecture is not capable of improvement beyond a compressor overall pressure ratio (OPR) of 60 due to lack of cooling margins for the turbine and high temperatures in the aft compressor stages. For hybrid gas electric propulsion (HGEP) thermal management for MW-size motors is a major barrier. The goal of this project was to evaluate the feasibility (considering safety, sfc, heat capacity and weight) of heat pipe cooling for jet engines using organic nanofluids as the working fluid to alleviate concerns related to liquid metal heat pipes.
