Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

In this study, the mixing of temperature-stratified liquid metal free-surface flow by a delta-wing obstacle installed on the channel bottom has been experimentally and numerically investigated in the presence of a transverse magnetic field. The surface temperature distribution of the channel was measured by using 25 thermocouples (TCs) embedded in the channel bottom, downstream of the obstacle, which was located upstream of the heater installed at the free-surface. The experiments were conducted for the turbulent flow region where Re = 12,000 and in the range of N = 0–5.02 in the presence of the transverse magnetic field. As for the laminar flow region, it is difficult to carry out the experiment, so the numerical simulations were conducted using Re = 2,300 and in the range of N = 0–10. According to the comparison of numerical results with and without the delta-wing obstacle in laminar flow region, the entire temperature distribution with the obstacle was warmer than that without the obstacle. This was consistent with the expectation that a delta-wing obstacle would increase thermal mixing.
