1. 1. CFD validation of a new gas turbinestage design with experimental data

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Claudia Florentina Balan; [2022]
   Keywords : ;

   Abstract : Gas turbines are present in two energy-intensive sectors: aviation and energy production. Improving the efficiency of gas turbines has a huge impact on the reduction of CO2 in the atmosphere, therefore many research groups are studying innovative strategies to improve the performance of these turbines.

3. 2. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Soumen Ghosh; [2022]
   Keywords : Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

   Abstract : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. READ MORE

4. 3. Meta-Modelling Based Design Optimization of Gas Turbine Blade Cooling Channels

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Namita Sharma; [2021]
   Keywords : Machine Learning; Meta Model; Data Science;

   Abstract : The aim of this paper is to investigate the use of Machine Learning to accelerate the processof gas turbine design optimization. Traditionally, the process simulations involved inoptimization are performed using commercial Computational Fluid Dynamics (CFD) softwaretools to find the best combinations of design parameters under specific conditionsand operational constraints.

5. 4. Investigation Of The Influence Of Geometrical Parameters On Heat Transfer In Matrix Cooling : A Computational Fluid Dynamics Approach

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Fabian Maletzke; [2021]
   Keywords : turbine; blade cooling; matrix cooling; latticework cooling; CFD; heat transfer; RANS;

   Abstract : Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. READ MORE

6. 5. Optimization of sprue design for advanced investment casting through FEA analysis

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Kanthee Prathan; [2020]
   Keywords : Design; FEM; FEA; Investment casting; Sprue design;

   Abstract : Investment casting is a complex manufacturing method with many challenges that must be solved before components of the right quality can be produced. TPC is a company that utilizes investment casting to produce a variety of products, lately the company has higher ambition in wanting to cast higher technical demanding component like heat resistant gas turbine blades.
