(a) Flow field and (b) isotherms inside the squalane droplet with a footprint radius L = 2.6 mm, static contact angle SCA = 41°, and temperature gradient G = 3.12 K/mm for different slip lengths. The red arrows denote the stagnation point at the droplet-air interface. The black and red curves denote the droplet-air interface at t = 0 and t = 2.5 s, respectively.
