To investigate the parameters of sucrose dust explosion, minimum ignition energy (MIE) and temperature (MIT) were evaluated. The experiments tested MIE under different conditions quantity, delay time (IDT), powder injection pressure (PIP). MIT particle sizes. results demonstrate that three was an open-up quadratic polynomial. When IDT, PIP 0.5 g (417 g/m3), 90 ms, 150 kPa, respectively, 58.9 mJ...

It is well-known that the calorific value and heat transfer speed of coal are closely related to quality index, affect explosion intensity maximum pressure dust explosion. In this paper, for different indexes studied experimentally, main parameters affecting elucidated by principal component analysis multivariate statistical analysis.

Context. Recent observations of brown dwarf spectroscopic variability in the infrared infer the presence of patchy cloud cover. Aims. This paper proposes a mechanism for producing inhomogeneous cloud coverage due to the depletion of cloud particles through the Coulomb explosion of dust in atmospheric plasma regions. Charged dust grains Coulomb-explode when the electrostatic stress of the grain ...

We present a theoretical model for Type Ib supernova (SN) 2006jc associated with a luminous blue variable (LBV)-like event. We calculate the presupernova evolution of the progenitor star, hydrodynamics and nucleosynthesis of the SN explosion, and the SN bolometric light curve (LC). The observed bolometric LC is constructed by integrating the UV, optical, near-infrared (NIR), and midinfrared (MI...
