Specific heat ratio effects of compressible Rayleigh—Taylor instability studied by discrete Boltzmann method [PDF]
Frontiers of Physics, 2021 Rayleigh-Taylor (RT) instability widely exists in nature and engineering fields. How to better understand the physical mechanism of RT instability is of great theoretical significance and practical value. At present, abundant results of RT instability have been obtained by traditional macroscopic methods.

Maximum heat ratio: bi-directional method for fast and slow sap flow measurements [PDF]
Plant and Soil, 2021 AbstractBackgroundAs sap flow research expands, new challenges such as fast sap flows or flows co-occurring with freeze/thaw cycles appear, which are not easily addressed with existing methods. In order to address these new challenges, sap flow methods capable of measuring bidirectional, high and slow sap flux densities (Fd, cm3cm−2 h−1), thermal ...
