The small groove surface flowing in the direction can effectively reduce the wall friction and reduce the energy consumption of transportation. For the gas pipeline with triangular ribs on the inner surface, the large eddy simulation is used to simulate different flow states, and the flow field velocity vector diagram, root mean square velocity profile line and Reynolds shear stress are analyzed. The simulation results show that the best drag reduction effect is achieved when the dimensionless dimension s+=20.7; the vortex formed by the turbulence is cut by the rib peak when passing through the rib to form a small reverse small vortex in the rib, and the fluid is the sliding friction between the wall surfaces which is converted into rolling friction, which reduces the frictional resistance; the velocity profiles of smooth tube wall, rib peak and valley bottom surface only differ greatly near the wall surface, and tend to be consistent far from the wall surface, and the rib pair the influence of the flow field mainly occurs in the near wall area.

Solid oxide fuel cells (SOFC) can convert the chemical energy of the fuel directly into electricity with high efficiency, low population and wide fuel applicability. Nibased ceramic material was used as the traditional SOFC anode. This anode shows carbon deposition and sulfur poisoning when natural gas was used as fuel for SOFC. Therefore, development of novel SOFC anode materials with good resistance to carbon deposition and sulfur poisoning has attracted considerable interest. This article reviews the recent developments of anode in SOFC with principal emphasis on the material aspects. In addition, the developments of carbon tolerant SOFC anode materials were presented from their properties. The emphasis will be placed on the development of perovskitetype anode material researches. Finally, this review will be concluded with its perspectives on the future research directions of this area.
