Modelling mushy regions

open access: yesMathematical and Computer Modelling, 1987
Abstract Two phase or mushy regions in which the phase boundary has a complicated morphology can exist in both pure and impure materials. In the former case, a macroscopic mathematical description can be given for the particular problem of melting by volumetric heating; no such procedure seems available for impure materials and this paper describes ...

Modelling of a strong dust event in the complex terrain of the Dead Sea valley during the passage of a gust front

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2016
The area of the Dead Sea valley and the adjacent regions are often affected by mineral dust. This study focuses on an extreme dust episode occurring on 22 March 2013, where near-surface dust concentrations of up to 7000 µg m−3 were encountered in the ...
