Boundary Layer Effects in Turbomachines


Book Description

The report is a study organized by the AGARD Propulsion and Energetics Panel with the collaboration of the Fluid Dynamics Panel and contains the papers, discussions and conclusions from the culminating meeting held at ONERA, France, during April 1972. The study provided opportunities for fruitful exchanges between aerodynamicists and engine specialists concerned with turbomachines, from the major aeronautical nations within NATO. The study resulted in clarification of the current states of knowledge within the two specialities relevant to turbomachines and highlighted the interest and importance of past and current research, while the discussions indicated a number of avenues for further work.

Cold-air Performance of Compressor-drive Turbine of Department of Energy Upgraded Automobile Gas Turbine Engine. 1: Volute-manifold and Stator Performance


Book Description

The aerodynamic performance of the inlet manifold and stator assembly of the compressor-drive turbine was experimentally determined with cold air as the working fluid. The investigation included measurements of mass flow and stator-exit fluid torque as well as radial surveys of total pressure and flow angle at the stator inlet and annulus surveys of total pressure and flow angle at the stator exit. The stator-exit aftermixed flow conditions and overall stator efficiency were obtained and compared with their design values and the experimental results from three other stators. In addition, an analysis was made to determine the constituent aerodynamic losses that made up the stator kinetic energy loss. (Author).

Engineering Turbulence Modelling and Experiments - 3


Book Description

This book presents and discussses new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. At present, turbulence is one of the key issues in tackling engineering flow problems. Powerful computers and numerical methods are now available for solving the flow equations, but the simulation of turbulence effects which are nearly always important in practice, is still in an unsatisfactory state and introduces considerable uncertainities in the accuracy of CFD calculations. These and other aspects of turbulence modelling and measurements are dealt with in detail by experts in the field. The resulting book is an up-to-date review of the most recent research in this exciting area.
