\chapter{Introduction}

The aim of this thesis work is to understand how High-Pressure Supersonic Turbines react to the unsteady and unstationary flow conditions when they operate with Rotating Detonation Engines. 

In recent years this problem has been investigated by several authors. Sun and et al[1] has investigated the effects of the diverging nozzle downstream of Rotating Detonation Engines. They have found out that the integrating diverging nozzle to Rotating Detonation Engines reduces the total pressure and temperature load downstream of Rotating Detonation Engines. Liu and Panigua[2] has also tried to intregrate this type of combustor with turbines by changing endwall shape of the first stage of the turbines. A modified endwall design has prevented the unstarting of the stator passage and enabled significant gain in performance. Paniagua and et al[3] has investigated also bladeless turbine configuration for the supersonic inlet flow. This has been done through a wavy hub surface which enables shocks and expansion fans and generates torque. Sousa[4] has also studied the designing of Supersonic Turbine according to the flow conditions downstream of Rotating Detonation Engine.

This master thesis work has the motivation to design a suitable supersonic turbine  to be integrated with pressure gain combustors.
