Acoustic levitation and infrared thermography: a sound approach to studying droplet evaporation

Herein we report a new technique combining acoustic levitation and infrared thermography to directly monitor droplet surface temperatures. Using it, temperature profiles were recorded during the evaporation of deionized water, methanol, n -propanol, and isopropanol. Results support the viability of...

Description
Summary:Herein we report a new technique combining acoustic levitation and infrared thermography to directly monitor droplet surface temperatures. Using it, temperature profiles were recorded during the evaporation of deionized water, methanol, n -propanol, and isopropanol. Results support the viability of this inexpensive and easily-accessed technique for studying chemical and physical changes in droplets. A new low-cost technique combining acoustic levitation and infrared thermography for studying the surface temperature of isolated droplets is outlined.
