1. 1. Establishing a methodology to investigate factors that affect Tip Leakage Loss : In a small scale Organic Rankine Cycle (ORC) turbine

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Anand Ashok Kaushik; [2022]
   Keywords : Ansys CFX; CFD; ORC; Turbines; Tip leakage; Internal flow; Loss; Entropy; Correlations;

   Abstract : With growing awareness and necessity for the world to move towards more sustainable (energy saving) forms of power generation, focus on the commercial use of Organic Rankine Cycle (ORC) turbine systems has subsequently increased in turn. ORC systems with their modular design can thus help in recovering heat, obtained as a byproduct from a variety of industrial processes, and thereby increase their overall system efficiency.

3. 2. Numerical Analysis Of 2D And 3D losses In Organic Rankine Cycle Turbine

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Pranav Rane; [2021]
   Keywords : Computaional Fluid Dynamics; CFD; Turbine loss; Profile loss; Tip leakage loss; 2D loss; 3D loss; ANSYS CFX; ANSYS Fluent; Organic Rankine Cycle Turbine; Parametric Study;

   Abstract : World resources are becoming more and more scarce due to the increasing demand. Hence, the industry is moving towards sustainable development in order to suffice the needs of the future generations. Electricity is one such resources that account for 90% of the daily utility. In Sweden alone 378 TWh of electricity is consumed over a year. READ MORE

4. 3. Evolution of Cavity Tip Vortices in High-Pressure Turbines

   University essay from Uppsala universitet/Elektricitetslära

   Author : Albin Berglund; [2017]
   Keywords : CFD; turbomachinery; tip gap; fluid dynamics; cavity; rotor blade;

   Abstract : This degree project in applied physics studies the tip gap flows over the rotor blades of a high-pressure turbine. The rotor blade used in the study has an improved design that utilizes both a cavity tip and an uneven profiling to reduce turbine loss. READ MORE

5. 4. BWR In-Core Instrumentation Sensitivity to Material and Geometrical Distortions

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mikael Nivala Fernberg; [2016]
   Keywords : ;

   Abstract : Several BWR utilities are adopting practices for determining the state of control rods based on the neutron sensitive LPRM and gamma sensitive TIP measurement systems of the nuclear reactor core. This method is in this study evaluated by quantitatively analyzing the detector sensitivity to several material and geometrical distortions in the detector vicinity, using the Los Alamos National Laboratory stochastic Monte Carlo code MCNP5 and the Westinghouse 3D core simulator POLCA7.

6. 5. Method development for investigation of real effects on flow around vanes

   University essay from Mekanisk värmeteori och strömningslära

   Author : Jonathan Mårtensson; [2010]
   Keywords : Master s Thesis; Method Development; Real effects; Turbomachinery; Turbine Flow; Secondary Flow; ICEM; Block Mesh Topology; Tip Gap;

   Abstract : In the development of turbo machinery components it's desirable to not spend more time than necessary when setting up aero-thermal calculations to investigate uncertainties in the design. This report aims to describe general thoughts used in the development of an ICEM-mesh script and the possible configurations in the script file which enables the user to build mesh-grids with/without clearance gap at the hub and/or shroud for different blade geometries.
