    You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. The focus of the book then covers two essential areas - heat transfer and fluid mechanics: topics with different finite element formulations. The heat transfer applications begin with the classical one-dimensional thin-rod problem, followed by a discussion of the two-dimensional heat transfer problem including a variety of boundary conditions.

    Downloadable (with restrictions)! In the paper the results of an experimental investigation developed on a small turbocharger turbine for automotive application are presented, including the effect of the waste-gate valve opening. The study was focused on the evaluation of turbine efficiency, especially under unsteady flow conditions typically occurring in automotive turbocharged engines. Experimental and Numerical Study of Return Channel Flow Influence on Surge Margin of a Multi-Stage Centrifugal Compressor An Evaluation of Vaneless Diffuser Modelling Methods as a Means of Improving the Off-Design Performance Prediction of Centrifugal Compressors Aerodynamic and Heat Transfer Optimization of One Stage Air-Cooled Turbine.

The numerical simulation and experimental work presented in this paper concentrates on the potential gain in turbine expansion ratio and eventual power output as well as the corresponding effects on efficiency as a result of operating the turbocharger in its active Cited by: 8.

The objective of this program was the design and fabrication of a air-cooled high-temperature radial turbine (HTRT) intended for experimental evaluation in a warm turbine test facility at the LeRC.

For small-scale cycles, radial inflow turbines (RIT) are the prevailing choice and one of the key components. A mean line design procedure for sCO 2 RIT is developed and design space exploration conducted for a kW-class turbine for a low-temperature waste-heat utilization sCO 2 Brayton cycle.

The purpose is to raise the efficiency of the compression system. The report describes the analytical, experimental, and developmental efforts that were conducted to design, fabricate, test, and evaluate turbine-rotor blade to rotor disk (blade/disk) attachment methods for an air-cooled turbine rotor in a small gas turbine engine.

There are two types of radial-inflow turbines: the cantilever radial-inflow turbine and the mixed-flow radial-inflow turbine. The cantilever-type radial-inflow turbine is infrequently used because of its low efficiency, production difficulties, and rotor blade flutter problems. On the other hand, the mixed-flow radial-inflow turbine is a widely.

Abstract. Organic Rankine cycle (ORC) development started in the s and followed the development of steam engines. In spite of Carnot's foresight of using other fluids than water, it took until the middle of the 20th century to benefit from the thermodynamics analysis to take advantage of the inherent flexibility of the ORC, to optimize the use of low-quality heat sources.

Centrifugal compressors, sometimes called radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. They achieve a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or kinetic energy is then converted to an increase in potential energy/static pressure by slowing the flow through a diffuser.
