Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

An implicit numerical scheme is developed to compute the transient one-dimensional flow of a two-phase mixture described by an unequal phase velocity (nonhomogeneous) model. This method is based on the modified FLASH-4 technique, but it suffers few of the drawbacks of other solution techniques recently used in the RELAP 4 and RETRAN computer codes. Significant advantages of the method are its consistency, stability, and ease of programming for complicated flow networks. The numerical scheme has been incorporated into a computer code and used to calculate three flow situations: a single-phase gas (ideal gas shock tube) a single-phase liquid (subcooled water blowdown) a two-phase blowdown (the Edwards experiment).
