Current Technology Situation and Research Progress of Artificial Snowmaking
Zhileng xuebao, 2021 The principle of snowmaking is simple, however the process is complex and highly dependent on environmental conditions. In recent years, to achieve the goal of "300 million people on ice and snow" and to host the "2022 Beijing Winter Olympic Games" China

Electron microscopy and calorimetry of proteins in supercooled water. [PDF]
Sci Rep, 2022 Some of the best nucleating agents in nature are ice-nucleating proteins, which boost ice growth better than any other material. They can induce immersion freezing of supercooled water only a few degrees below 0 degrees C.

Complexity, Volume 2019, Issue 1, 2019., 2019 Retractable roofs are commonly used in designing large‐span stadiums because of their versatility. However, retractable roofs are subject to sudden changes in shape, and thus, factors in addition to those considered for conventional roofs need to be taken into account.

Assessing the Sustainability of Ski Fields in Southern Japan under Global Warming
Advances in Meteorology, Volume 2018, Issue 1, 2018., 2018 This is the first study in assessing the impact of climate change on Japanese ski fields with ensemble dynamical downscaling simulations. We target three ski fields in Ehime Prefecture, a southern border area for skiing in Japan. Our field survey revealed that a field located above 1200 m altitudes currently operates on natural snow supply, but those ...

Measuring the Elastic Modulus of Snow
Geophysical Research Letters, Volume 44, Issue 21, Page 11,088-11,096, 16 November 2017., 2017 Abstract The elastic modulus is the most fundamental mechanical property of snow. However, literature values scatter by orders of magnitude and hitherto no cross‐validated measurements exists. To this end, we employ P wave propagation experiments under controlled laboratory conditions on decimeter‐sized snow specimen, prepared from artificial snow and ...

Two-Phase Flow Process and Atomization Law of Nucleator Nozzle for an Outdoor Snow Maker
Zhileng xuebaoNucleator nozzles play an important role in promoting the rapid nucleation, crystallization, and snow formation of artificial snow droplets. A visual experimental platform was designed to investigate the gas-liquid two-phase flow process inside the ...
