Seismic rehabilitation provides existing buildings with more resistance to seismic activity, ground motion, or geotechnical failure due to earthquakes. Performance-based rehabilitation is a general concept through which the retrofitting criteria are defined regarding to performance objectives when the structural and nonstructural members are subject to different levels of earthquake hazards. In...

    In this study, it was shown that how CO2 and H2S were removed from a natural gas stream, using a nanofluid containing nanoporous graphene in Diehanolamine (DEA). Before running the experiments, the appropriate values were chosen for the nanosheet dosage and the liquid and gas flow rates in the absorption experiments, which were performed in a laboratory scale wetted wall column. In the expe...

An inertial fusion energy (IFE) wetted wall configuration provides the advantage of a renewable armor to accommodate the threat spectra. Key issues are the re-establishment of the thin liquid armor and the state of the chamber environment prior to each shot relative to the requirements imposed by the driver and target thermal and injection control.

Experimental and numerical studies of the fluid dynamics of thin liquid film wall protection systems have been conducted in support of the ARIES-IFE study. Both the porous “wetted wall” concept, involving low-speed injection through a porous wall normal to the surface, and the “forced film” concept, involving high-speed injection through slots tangential to the surface, have been examined. Thes...
