Opis:: Based on basic equation and boundary layer theory of pneumodynamics, the thesis conducts numerical modeling and theoretical analysis on the last stage of turbine characteristics at a small volume flow by using FLUENT, gives an emphasized analysis on the position of first occurrence of backflow and its expansion direction and comes up with flow structure of the turbine flow field at last stage in the small volume flow condition. In connection with specific experiments, it puts forward the flow model of backflow occurring in the last stage field and the solution to the model. The flow field at last stage for a 100MW turbine in the small volume flow condition that is calculated by using the model is basically in conformity to the actual result.

Opis:: This paper presents results of application of a viscid fluid model to calculate flow around a finite-span hydrofoil. The presented calculations were performed with the use of SOLAGA software developed by this author. The used theoretical model of viscid liquid motion was described, consisted of averaged liquid motion equations and Spalart-Allmaras one-equation model of turbulence. Also, a numerical model based on the finite volume method was shortly presented. Calculation results were shown in the form of distribution diagrams of pressures, longitudinal component of velocity and longitudinal component of rotation velocity. Additionally, the presented characteristics of the lifting force coefficient and drag force coefficient were compared with experimental data.

Tematy:: finite volume

overlapping mesh
fluid-structure interaction
Opis:: A Finite Volume (FV) algorithm is presented to investigate two-dimensional hydrodynamic problems including viscous free surface flow interaction with free rigid bodies in the case of large and/or relative motions. Two-phase flow with complex deformations at the interface is simulated using a fractional stepvolume of fluid algorithm while it is also capable of representing a high quality wave tank, according to implemented temporal discretisation. Rigid body motions are also captured using two overset meshes. Flow variables are transferred using a simple fully implicit non-conservative interpolation scheme which maintains the second-order accuracy of implemented spatial discretisation. A code is developed and an appropriate set of problems are investigated. Results show a good potential to develop a virtual hydrodynamics laboratory.
