1. Range impact of a high velocity aft-propeller on a subsonic aerodynamic body
University essay from Luleå tekniska universitet/RymdteknikAbstract : This master’s thesis is aimed to examine the possible range increase of a ballistically fying body equipped with a propeller working at transonic velocities. To determine whetherthe propeller will provide an improvement in range, results from simulations are compared to corresponding cases of similar bodies fying without a propeller. READ MORE

2. Forced response numerical investigation of a transonic compressor rotor
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

3. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

4. Design of a High Subsonic Nozzle for a Transonic Linear Cascade Operating at Near Stall Conditions
University essay from KTH/EnergiteknikAbstract : This thesis presents the results of computational fluid dynamics (CFD) design calculations of a subsonic nozzle operating at Mach number 0.85 in a transonic linear cascade wind tunnel. The purpose of the nozzle is to accelerate a fluid by decreasing the pressure energy and raising the kinetic one. READ MORE

5. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE
