Research conducted at Texas A&M AgriLife research facilities may answer the question of how airflow patterns can play a role in the transmission and potential mitigation of the spread of
With global warming putting a strain on resources, the need for developing Arctic shipping routes has increased. However, ice-breaking ships need to function more efficiently. One way to better their design is by improving upon the current algorithms used to study ice resistance, a critical factor for efficient ice breaking. Scientists have now developed a numerical model capable of predicting the ice resistance encountered by icebreakers.
The risk of explosions in coal mines is an important subject that requires a comprehensive understanding of explosion dynamics, mining operations, and mining safety. Recent spontaneous combustion events in New South Wales (NSW) and Queensland have resulted in mine evacuations due to a Trigger Action Response Plan (TARP) being activated at the evacuation level. A sound basis is required for defining the high-risk working zones, mine operational exclusion zones for both emergency activities and mine design considerations, and public exclusion zones during emergency situations. This paper presents a methodology for predicting and defining explosion risk around the coal mine portals developed using Computational Fluid Dynamics (CFD) and experimental results from an advanced blast simulator simulating blast waves exiting a portal entry and propagating over an outside mine site terrain. The methodology can be applied to generate exclusion zones that account for the effects of blast waves ema
