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, three-dimensional liquid-metal magnetohydrodynamic flows in a rectangular hairpin duct with parallel inflow and outflow channels, placed under uniform magnetic fields, are analyzed based on a computational fluid dynamics method. Detailed information on flow velocity, pressure, current, and electric potential in magnetohydrodynamic duct flows is predicted. In the side layers of the inflow and outflow channels, higher velocities are observed, and M-shaped velocity profiles are presented. In the turning segment, the velocity distribution is very complex, yielding complicated induced current therein. The electromagnetic characteristics of the complicated liquid-metal flows are examined in terms of the electromotive and electric-field components of the current. The pressure almost linearly decreases along the main flow direction, except for in the turning segment. Cases with different Hartmann numbers are examined, and the larger the Hartmann number is, the larger the pressure drop is. However, the nondimensional pressure gradient is smaller in cases of larger Hartmann numbers.
