Early assessment of thermal analysis rotating detonation engine.

Abstract

Rotating Detonation Engine (RDE) has been proven for its high thermal efficiency and performance but with limited time operation because of the heat issues. This paper deals with early assessment of wall heat loads for thermal analysis of RDE. Initial experimental result will be shown for the uncooled rotating detonation engine, this RDE has successfully achieved detonation at various equivalence ratio reactant but with limited time operation because of the heat issues, the temperature produced to the wall of RDE is near to maximum critical temperatures of the mild steel wall of RDE. The wall temperature was observed to be in the range of 1100 °C. From the uncooled result, it will be redesigned to include active cooling system to tackle the heating issue with several parameters such as the mass flow rate of coolant and appropriate volume tank of coolant to be taken into consideration. Thus, the aim of this study is to determine the maximum duration of uncooled and cooled RDE to run at stable detonation condition.
