Byung Ho Choi, Kyeong Ok Kim, Jin-Hee Yuk, Han Soo Lee

Ocean Dynamics > 2018 > 68 > 12 > 1759-1777

The 1953 North Sea floods, the Big Flood, was one of the worst natural disasters in Europe in modern times and is probably one of the most studied severe coastal floods. Several factors led to the devastating storm surge along the southern North Sea coast in combination of strong and sustained northerly winds, invert barometric effect, high spring tide, and an accumulation of the large surge in the...

Young Hwan Kim, Jae Won Lee, Han Soo Lee, Geun Il Park, more

Energy Procedia > 2013 > 39 > Complete > 311-318

A voloxidizer for hot cell demonstrations that handles spent fuel of high radiation virulence in a limited space should have a small size and not scatter in its outlet. This study predicts the terminal velocity of U3O8 by using the terminal velocity of SiO2, which would determine the optimum air flux. We obtained a theory terminal velocity of SiO2 and conducted an experiment for verification. In a...
