Improvement of part-load performance of gas turbine by adjusting compressor inlet air temperature and

Frontiers in Energy 2022, Volume 16, Issue 6,   Pages 1000-1016 doi: 10.1007/s11708-021-0746-z

Abstract: A novel adjusting method for improving gas turbine (GT) efficiency and surge margin (SM) under part-loadThe equilibrium running lines calculated through the calculation method involve three part-load conditionsFor the best GT performance of a given load, the IGV could be adjusted according to inlet air temperatureIn addition, inlet air heating has a considerable potential for the improvement of part-load performanceThe IGV can be left unadjusted, even when the load is as low as 50%.

Residual stresses in coating-based systems, part I: Mechanisms and analytical modeling

ZHANG Xiancheng, WU Yixiong, XU Binshi, WANG Haidou

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 1,   Pages 1-12 doi: 10.1007/s11465-007-0001-2

Abstract: Thin films and multi-layered coatings comprised of different classes of materials are often used for various functional devices. The thermo-mechanical integrity of these systems is becoming a major concern and is strongly related to the residual stresses because of the fabrication processes. In this paper, the sources of the residual stresses in the coating-based systems and the concept of misfit strain were briefly reviewed. Analytical models were developed to predict the residual stresses in multi-layered film structures or coating-based systems using the force and moment balances. In addition, the residual stress distributions in the func tionally and compositionally graded coatings were also analyzed.

Taking Warning from the Eastern Part Elegant Landscape Maturing Slowly——On Landscape Architectural Developmentin the Western Part of China

Meng Zhaozhen

Strategic Study of CAE 2000, Volume 2, Issue 10,   Pages 56-58

Abstract:

First of all, it is necessary carried out comprehensive national land planning and individual design from the high plane of harmonious sustainable development between man's production and natural environment.

The essence of cities at present should be an environment for human settlement and living. The relation between urbanization process and natural environment is neither to diametrically oppose nor to damage each other. The image of the city is not only buildings and streets but also a mix of cities, architecture and natural environment, i.e.an artificial beauty merging into nature. Man's bright future will be to put cities and buildings into green environment.

The most important thing for construction of scenic and historical places and city parks and gardens is now to protect the natural resources of the site. It is wrong to follow limelight from others. Each city should creates its own feature from local natural environment and cultural tradition.

Elegant landscape will mature slowly. Great thing always gets a late prosperous termination of an affair.

Abstract:

The reliability-based design optimization, the reliability sensitivity analysis and robust design method are employed to present a practical and effective approach for reliability-based robust design optimization of vehicle components. A procedure for reliability-based robust design optimization of vehicle components is proposed. Application of the method is illustrated by reliability-based robust design optimization of axle and spring. Numerical results have shown that the proposed method can be trusted to perform reliability-based robust design optimization of vehicle components.
