Context. Dust grain dynamics in molecular clouds is regulated by its interplay with supersonic turbulent gas motions. The conditions under which interstellar dust grains …
This paper reports the findings from a three-dimensional direct numerical simulation conducted to investigate the turbulent flame behaviors of premixed high-hydrogen content …
A series of direct numerical simulations (DNSs) of forced compressible isothermal turbulence in a periodic box are conducted by using an eighth-order compact finite …

It has recently been shown that turbulence in the interstellar medium can significantly accelerate the growth of dust grains by accretion of molecules, but the turbulent gas density …
We study the linear growth and non-linear saturation of the 'acoustic Resonant Drag Instability'(RDI) when the dust grains, which drive the instability, have a wide, continuous …
