Target geometry of our study is a head-to-head droplets formed between coaxial cylindrical rods. They never coalesce even though one pushes the droplets against each other if there exists a certain temperature gradient over the free surface under the condition of the non-zero temperature coefficient of the surface tension. We focus upon unique behavior of the particles suspended in the non-coalescence head-to-head droplets. Several kinds of patterns emerged in the hotter droplet will be introduced. Spatio-temporal particle behaviors are reconstructed by applying three dimensional particle tracking velocimetry (3-D PTV). This phenomenon is a potential way for the mixing in the liquid droplet without any mechanical components such as motors.
