Numerical study of internal flow field and flow passage improvement of an inlet particle separator

Florian PAOLI, Tong WANG

Frontiers in Energy 2011, Volume 5, Issue 4, Pages 386-397 doi: 10.1007/s11708-011-0156-8

Abstract: passage of an inlet particle separator.No particle has been included in the gas flow for a -epsilon turbulence model.Therefore, the profile of streamlines along the original passage has been considered.Then the flow passage improvement method has focused on the separation area.As a result, the numerical calculations demonstrate that the flow passage improvement method applied

Oil and gas strategy passage construction and management innovation of CNPCI

Huang Weihe

Strategic Study of CAE 2012, Volume 14, Issue 12, Pages 19-24

Abstract:

The oil and gas pipeline system is the artery of energy for the national economy development. With China’s increasing dependence on foreign oil and gas, accessibility of oil and gas strategic passages and availability of safe and stable energy supply are the urgent affairs. In the construction process of the onshore oil and gas strategic channels, by the independent innovation based on the “1+ N” cooperative model, the pipeline design, construction, equipment localization and high-pour-point and viscous crude oil transportation and other key technologies have been formed, and the large oil and gas pipeline networks with the scale of a total length of 6×104 km, transport capacity of 1.7×108 t of oil, transmission capacity of 1.4×1011 m³ of natural gas have been built. During the operation and management of the large pipeline networks, through the establishment of e-SAME security consistency systems, the operation and management organization, asset integrity management, market guarantee and emergency maintenance and other subsystems have been developed, and the enterprise security goals have been ensured.

Management System and Education Model in Developed Countries for Engineering Management Major Education Improvement

Jian-ya Jiang,Yang-wei Rao

Frontiers of Engineering Management 2014, Volume 1, Issue 4, Pages 406-409 doi: 10.15302/J-FEM-2014049

Abstract: Different developed countries have differences in regulations for engineering management systems. The related education modes and their curriculum arrangement in universities in the US, UK, and Germany show their specializations. Through comparative research into engineering management systems and professional education modes between China and these developed countries, the paper proposes suggestions for improving the education of engineering management majors in China, which could speed up development of Chinese engineering general contracting enterprises and engineering project management enterprises.

Equal Stress Should Be Laid on Bridge and Tunnel in the Trans-Yangtze Traffic Project

Qian Qihu,He Yishou

Strategic Study of CAE 2001, Volume 3, Issue 5, Pages 32-34

Abstract:

The trans-Yangtze traffic project plays an important role in the steady development of China´s economy in the 21st Century. In making choice of the transriver project scheme it is not wise to take bridge scheme as the only way out. Instead,equal stress should be laid on bridge and tunnel,so that both bridge and submerged tunnel can give full play to their own strong points in light of local condition.
