TL;DR: In this paper, the effect of operating pressure on the WGS reaction rate over an iron-based high-temperature catalyst, and a Co-Mo based sour-shift catalyst, was investigated using simulated coal-derived syngas at 450°C.

TL;DR: In this article, a unit recuperator with offset strip fins was fabricated using furnace-brazing technology in vacuum atmosphere, and experiments were conducted by varying the mass flow rate and inlet temperature of the hot air stream in the range of 1.5−4g/s and 250−500°C, respectively.

TL;DR: In this paper, the multiphoton dissociation of 32SF6 has been studied in the presence of several inert gases and different collisional quenching efficiencies are obtained for the various inert gases.
Abstract: The multiphoton dissociation of 32SF6 has been studied in the presence of several inert gases. The reciprocal dissociation yields increase with increasing total pressure in a nonlinear way for the conditions applied. Different collisional quenching efficiencies are obtained for the various inert gases. From the quenching efficiencies information on the optical pumping process may be obtained.

TL;DR: In this article, an experimental investigation into the effectiveness of vortex generator jets in controlling secondary flows in two-dimensional S-duct diffusers was performed in uniform and distorted inflow conditions and performance evaluation of the diffuser was carried out in terms of static pressure recovery and quality of the exit flow.
Abstract: Results are presented of an experimental investigation into the effectiveness of vortex generator jets in controlling secondary flows in two-dimensional S-duct diffusers. The experiments were performed in uniform and distorted inflow conditions and the performance evaluation of the diffuser was carried out in terms of static pressure recovery and quality of the exit flow. In the case with inflow distortion, tapered fin vortex generators were employed in addition to vortex generator jets to control flow separation that was detected on the wall with inflow distortion. Detailed measurements including total pressure, velocity distribution, surface static pressure, skin friction, and boundary layer measurements were taken at a Reynolds number of 7.8×10 5 . These results are presented in terms of static pressure rise, distortion coefficient, and total pressure loss coefficient at the duct exit

TL;DR: In this article, the three-dimensional pressure field of the Dallas tornado, April 2, 1957, is integrated from a distribution of observed tangential wind speeds, and the effects of the moving pressure field on hypothetical vented and unvented buildings are computed.
Abstract: The three-dimensional pressure field of the Dallas tornado, April 2, 1957, is integrated from a distribution of observed tangential wind speeds. A total pressure drop of 60 mb. is computed at ground level at the axis. Variations in tornado funnel geometry are explained by changes in moisture content of the involved air and system-wide pressure changes. The effects of the moving pressure field on hypothetical vented and unvented buildings are computed. The results indicate that a dwelling, which could lose in 5 seconds about 75 percent of an imposed pressure difference, would most likely not yield due to internal pressure alone, if the imposed pressure difference were like that of the Dallas tornado.
