Nonisothermal desorption of droplets of LiBr salt solution on a heated wall

Nonisothermal desorption and crystallization of droplets of aqueous salts solution of H2O/LiBr were studied experimentally. A droplet was placed on a horizontal heated wall. The initial concentration of salt C-0 varied within 0-53 %. The wall temperature T-w varied within 80 - 235 degrees C and ambient air pressure was 1 bar. It was shown that the desorption time t(1) decreases sharply with increasing T-w and at T-w < 150-160 degrees C. The desorption time t(1) is the time until the onset of crystallization. The desorption time t(1) is quasi-constant at T-w > 160 degrees C and increases with growth in C-0.
