ESR13, Abhishek Dubey presented a short paper titled “A Review of Recent Advances in the Combustor and Blade Cooling Methods for Pressure Gain Applications” at the Joint Meeting of International Workshop on Detonation for Propulsion (IWDP) and International Constant Volume and Detonation Combustion Workshop (ICVDCW) held at TU Berlin. Co-authors of the paper are ESR14, Sreenath Purushothaman, A. Sorce and A. Traverso (TPG UNIGE).
This paper presents a review of the recent advances in the gas turbine combustor and blade cooling methods in order to identify the most promising thermal management solutions for pressure gain combustion. Cooling effectiveness for blade cooling are discussed and innovative cooling concepts such as propellant injection cooling, pulse impingement cooling and bladeless turbine are also addressed. Additionally, the development of cooling models for cycle analysis and the cooling-associated performance losses are also investigated.
