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.

To investigate the clogging of high-efficiency particulate air (HEPA) filters by soot during fire events, the Carman-Kozeny relation, which is an equation of pressure drop for fluid passing through a particle packed layer, has been applied to the pressure drop evaluation of fluid through the soot deposition layer on a HEPA filter. Particular attention has been paid to the characteristics of the soot and the compressibility of the soot deposition layer on the HEPA filter. It has been shown that the pressure drop of fluid through the soot deposition layer depends on the specific resistance and compression coefficient of the soot deposition layer as well as on the amount of soot deposited per unit area of HEPA filter and the filtration air flow velocity.
