The availability of tools to control mosquito (Diptera:Culicidae) vectors that transmit disease is often limited by a variety of economic, environmental and social issues. In emergency conditions (epidemics, hurricanes, floods etc.), the application of pesticides as space sprays (either by ground or air) is the common method of choice in order to rapidly limit adult local mosquito production in...

The coupling through both drag force and volume fraction (of gas) of a kinetic equation Vlasov type system Euler or Navier–Stokes (in which the explicity appears) leads to so-called thick sprays equations. Those equations are used describe (droplets dust specks in surrounding disperse phase is non negligible. As for other multiphase flows systems, issues related linear stability around homogene...

Schlieren image velocimetry (SIV) is based on light deflection through flow heterogeneities and cross-correlations. This a low-cost relatively low complexity technique that allows measurement of the droplet velocity field in large region spray. A Z-type Toepler schlieren system with high-speed camera was used to determine mean vertical horizontal velocities, as well cone angles sprays produced ...
