in order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in isfahan. the experiment was conducted as split plots in a randomized complete blocks design with three replications in isfahan (51° 48' e, 32° 40' n).main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class a and cultiv...

2D solar-driven interfacial evaporation (2D SIE) is a low-cost, environmentally friendly water treatment solution. Studies have improved the performance of single-stage close to its upper bound in controlled environments. However, most critical parameter – rate was only assessed by laboratory-scale measurements and data are typically obtained under specific set conditions. Previous studies did ...

A theoretical investigation of the effect gas velocity oscillations on droplet number density and evaporation rate is presented. Oscillations in cause a wave, i.e. an inhomogeneous, unsteady variation concentration. The as it propagates downstream at mean flow speed, causes modulation local rate, creating vapour wave with corresponding equivalence ratio. present work devises analytical formulat...
