What is the cooling rate of a superhydrophobic surface
submitted to rain ?
Heat exchange between a bouncing drop and a superhydrophobic substrate, S. Shiri and J. C. Bird, PNAS, 114, 6930 (2017)
Using scaling arguments, derive the time evolution of
temperature on the substrate after the rebound of the drop
Derive a scaling relation between Q the amount of heat transferred and the radius R of the impacting drop.
The contact time scales as (ρR3/γ)1/2

The vertical flux by dust mode is calculated as the sum of the contributions of each wind bin discretization and then distributed in the three SPLA aerosol modes: fine mode
While this is already a useful technique, the patterning capability becomes even greater as the lines are brought together – due to the fact that the driving force for dewetting
The retrieved time series of partial and total ozone columns are validated with ground-based correlative data (Brewer, Dobson, UV-Vis, ozonesondes, and Lidar). The observed total
This method can not reproduce the organisation of cold clouds as crystals but it allows one to scale the size of large samples with the trapping parameters and the number of

specific heat contains contributions not only from the strongly coupled levels which are observed in phonon scattering experiments but also from more weakly coupled levels..
