Suspended Sediments in Environmental Flows: Interpretation of Concentration Profiles Shapes

open access: yesHydrology, 2022
In environmental flows, field and laboratory measurements of suspended sediments show two kinds of concentration profiles. For coarse sediments, a near-bed upward convex profile is observed beneath the main upward concave profile.

Thermal-electrical analogy and inertia for thermal performance of building envelops [PDF]

open access: yesMATEC Web of Conferences, 2020
For transient thermal performance of building envelops adequate parameters are needed to capture the time lag and decrement factor. It is surprising that, in the formal electrical analogy, "inertia" is not represented by same components in fluid ...

The ice-nucleating ability of quartz immersed in water and its atmospheric importance compared to K-feldspar

open access: yesAtmospheric Chemistry and Physics, 2019
. Mineral dust particles are thought to be an important type of ice-nucleating particle (INP) in the mixed-phase cloud regime around the globe. While K-rich feldspar (K-feldspar) has been identified as being a particularly important component of mineral ...
