Ali BELHOCINE, Mostefa BOUCHETARA

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 2,   Pages 150-159 doi: 10.1007/s11465-013-0266-6

Abstract:

The main purpose of this study is to analyze the thermomechanical behavior of the dry contact between the brake disk and pads during the braking phase. The simulation strategy is based on computer code ANSYS11. The modeling of transient temperature in the disk is actually used to identify the factor of geometric design of the disk to install the ventilation system in vehicles. The thermal-structural analysis is then used with coupling to determine the deformation established and the Von Mises stresses in the disk, the contact pressure distribution in pads. The results are satisfactory compared to those found in the literature.

Integrated energy in Germany–A critical look at the development and state of integrated energies in Germany

Saman AMANPOUR, Daniel HUCK, Mark KUPRAT, Harald SCHWARZ

Frontiers in Energy 2018, Volume 12, Issue 4,   Pages 493-500 doi: 10.1007/s11708-018-0570-2

Abstract: In the face of global warming and a scarcity of resources, future energy systems are urged to undergo a major and radical transformation. The recognition of the need to embrace renewable energy technologies and to move toward decarbonization has led to significant changes in the German energy generation, consumption and infrastructure. Ambitious German national plans to decrease carbon dioxide emissions on one side, and the unpredictable and volatile nature of renewable energy sources on the other side have elevated the importance of integrated energies in recent years. The deployment of integrated technologies as a solution to interlink various infrastructures creates opportunities for increasing the reliability of energy systems, minimizing environmental impacts and maximizing the share of renewable resources. This paper discusses the role of integrated energy systems in supporting of sustainable solutions for future energy transitions. Moreover, the reinforcement of this movement with the help of different technologies will be discussed and the development of integrated energy systems in Germany will be reviewed.
