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

Nonisothermal desorption and crystallization of droplets of aqueous salts solution of H 2 O/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 °C and ambient a...

Summary:Nonisothermal desorption and crystallization of droplets of aqueous salts solution of H 2 O/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 °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 °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 °C and increases with growth in C 0 .
