This Book is describing the way the 2D Fluid Mechanics Solver can be created with use of Object Oriented Programming. In this book You will find practical knowledge about Object Oriented Programming Its advantages and disadvantages and how C++ language can be used for science oriented projects. Moreover there are explained and described source code examples that are responsible for space discretization and solution of Convection-Diffusion and Euler Equations.

Rapid development of urban areas dramatically increases an energy demand. In order to respond to this fact and to ensure a proper diversification of its sources, renewable energy seems to be a reasonable solution. Savonius wind turbine meets all of the above expectations, while having unique features, contributing to its superiority over the commonly used turbines with a horizontal axis of rotation. The aim of this study was to develop a physical representation of the flow in the Savonius wind turbine, allowing to precisely compare alternative projects in terms of parameters of their work....
