Multiwavelength observations of SNR 1987A show that its morphology is rapidly changing at X-ray, radio, and optical wavelengths as the blast wave from the explosion expands into the circumstellar equatorial ring. Infrared emission arises from the interaction of dust grains with the hot X-ray emitting gas. We show that the IR emission provides important complementary information on the interacti...

Abstract To reveal the flame propagation and CO/CO2 generation characteristics of coal dust explosion, lignite cloud is studied through experiment numerical simulation in a horizontal pipeline apparatus. The result indicated that within 0.5 s after distance rapidly increases until explosion reaction sufficient. FLUENT used to simulate characteristics. It found error acceptable consistent with e...

Here, we present a numerical model for simulating the formation and evolution of gas dust cloud that forms after detonation high explosive charges in boreholes. This provides possible method converting substance ejected from an explosion funnel into discrete particles (smaller stones) calculating movement these condensed their interaction with air–gas flow; this uses framework equations multiph...
